Restoration of carbon cartridge for water. How to clean the Barrier water filter? Resin regeneration technology - how the ion exchange resin in the filter is restored

Filtration devices are present in many houses and apartments, providing their owners with clean, safe water. Household filters for water softening most often use special modules with ion exchange resin, which usually exhaust their service life before other cartridges included in the filtration system. In this case, there are two options - replacing the module or regenerating it.

Why and how regeneration is carried out

Opportunity to independently living conditions, performing repeated regeneration of the softening module significantly reduces the cost of operating the filter, especially since this procedure is simple and inexpensive.

The ion exchange resin in the water filter replaces calcium and magnesium ions, which are responsible for water hardness, with sodium ions. Filtered water becomes soft, which ensures that there is no scale inside household appliances. A concentrated solution of table salt restores the supply of sodium ions in the ion exchange resin and it can soften water again.

After each regeneration, the ion exchange resource of the module decreases, so the total number of possible regenerations is limited and sooner or later it will still have to be replaced.

The process of restoring an Aquaphor KN filter with a solution of table salt

Before starting the regeneration process, you will need to make simple preparations:

• Assemble a regeneration adapter, which may be included with the filter or sold separately. Insert the sealing gasket into the union nut and screw the nut tightly to the adapter. Place the tube onto the adapter fitting.
• Cut off the bottom of a regular plastic bottle.
• Prepare a saturated saline solution - take table salt for 2-2.5 liters of boiled water at the rate of 300 g per liter of water.

Now you can proceed directly to the regeneration of the Aquaphor KN filter:

1. Before starting work, you must relieve the pressure in the filter. To do this, close the water supply tap to the filter, and open the filter tap to clean water.
2. While pressing and holding the button on the filter cover, disconnect the module by unscrewing it counterclockwise.
3. Firmly insert the adapter into the KN module.
4. Screw the cut bottle to the adapter.
5. Place the module with a screwed bottle in vertical position, for example, in a jar. Lower the plastic tube of the adapter into the sink; the solution passed through the module will drain through it.
6. Pour the solution through the module, being careful not to allow any sediment to get into it.
7. After spilling saline solution You need to pass about another 2.5 liters of clean boiled water through the module.
8. Insert the regenerated module into the manifold block until it stops. Using light pressure, turn it clockwise until it clicks into place.

Once the filter is assembled, run water through it for about 10 minutes. Then close the clean water filter tap to ensure all connections are tight. Regeneration is complete and the filter can be used again.

Filter for drinking water Today it is far from uncommon. This useful device regularly provides its owners with clean drinking water. But, like any equipment, a water filter needs regular maintenance. One of the most labor-intensive operations is the regeneration of cartridges with ion-exchange resin. How to carry out regeneration quickly and correctly?

A high degree of purification in a household drinking water filter consists of three components. Firstly, it is the correct choice of filter type. Choosing the wrong type of filter will result in you being extremely dissatisfied with its performance, or you will spend too much money on filter maintenance. Secondly, this right choice filter model suitable for your water. Errors in choosing a model can result in insufficient purification of water from contaminants or rapid exhaustion of the filter cartridge resource. And finally, thirdly, effective work filter depends on correct and timely maintenance.

Maintenance of water filters largely depends on the design of the filter. Jug filters, faucet filters, single-stage tabletop filters do not cause any particular problems - as the resource is exhausted, the cartridge is simply replaced with a new one. Many filters have special devices that help you not miss the next cartridge replacement date.

Problems arise with the most common three-stage filters. Typically, such a filter includes a cartridge mechanical cleaning, cartridge for water softening based on ion exchange resin and cartridge post-treatment from activated carbon.

The total resource of household filter cartridges reaches 5000-7000 liters, which is quite enough to change them once a year. With the only exception - the resource of the cartridge with ion exchange resin depends on the hardness of the water entering it and is ensured only when regular regeneration.

What is ion exchange resin?

Ion exchange resins have been widely used in water filtration systems since the 1960s. It was then that developed countries paid attention not only to purifying water from mechanical impurities and pathogens, but also to limiting the content of dissolved salts in water (mainly calcium and magnesium salts).

Natural water can contain either a very small amount of such salts (melt “soft” water) or an excessive amount of them (“hard” water from some wells and artesian wells). It is impossible to get soap suds in hard water; when boiled, it produces strong scale in teapots and saucepans, and simply such water is not useful for the human body.

Ion exchange resin in the form of small amber-colored balls, it has the ability to capture calcium and magnesium ions from water, replacing them with sodium ions. As a result of this exchange, the water hardness is brought to a normal value.

In household filters, standard strong acid filters are most often used. ion exchange resin-gel-type cation exchanger. An example is resin Dowex HCR-S/S based on sulfonated styrene copolymer divinylbenzene. Despite the scary “chemical” name, this substance is absolutely stable and does not release any harmful impurities into the filtered water.

The main characteristic of an ion exchange resin is its volumetric ion exchange capacity. This capacity is measured in gram equivalents and shows the amount of salts dissolved in water that one liter of resin can absorb. For resin in household filters, the usual ion exchange capacity ranges from 1.5-2.1 g-equivalent per liter. Approximately about a liter of resin is usually contained in a standard filter cartridge type 10 SL.

Knowing the hardness of the water entering the filter, you can calculate the approximate resource ion exchange cartridge. Water hardness is determined by the salt content and is usually expressed in mEq/liter. By dividing the ion exchange capacity of the cartridge by the water hardness, you can find out the resource.

For example, if the water hardness is 4 mEq/liter and the ion exchange capacity of the cartridge is 2 gEq, the cartridge resource is 2 gEq/0.004 gEq/liter = 500 liters. An increase in water hardness leads to a decrease in cartridge life.

Fortunately, the process of absorption of calcium and magnesium ions is reversible. If there is an excess of sodium ions in the solution surrounding the resin, the process will go in the opposite direction - sodium ions will be absorbed, and calcium and magnesium ions will be released into the solution. This process is called regeneration of ion exchange resin. As a regenerating solution, you can use the cheapest substance containing sodium - table salt (sodium chloride).

Regeneration of the ion exchange resin can be carried out many times. Purely theoretically, the number of cycles is not limited. But the ion exchange resin is gradually poisoned by various impurities contained in the water (iron, chlorine) and loses its ion exchange capacity. This resin should be replaced. For a household filter, it is easier to buy a new cartridge.

How to maintain the water filter and regenerate the ion exchange resin?

The need to service a water filter is determined by a decrease in water flow through the filter or the appearance of scale in the kettle. To service a conventional three-stage filter, you must:

• Shut off the water supply to the filter by closing the inlet tap.
• Relieve the pressure in the filter housings by opening the clean water tap.
• Using the wrench included in the filter kit, unscrew the first housing along the water flow and remove the mechanical cleaning cartridge.
• Thoroughly clean the surface of the cartridge from dirt by rinsing it under running water with a brush. Rinse the filter flask.
• Install the mechanical cleaning cartridge and tighten the housing.
• Unscrew the middle housing using the wrench included in the filter kit and remove the ion exchange cartridge.
• Cartridges different manufacturers may have different structures, so the technology for regenerating ion exchange cartridges varies. Simple cartridges contain a homogeneous backfill of ion exchange resin. The resin from such a cartridge can be poured out and regenerated in a separate container. This will make the regeneration process more efficient. Cartridges from other manufacturers may have more complex structure and contain several layers. Such cartridges are regenerated without removing the resin.
• For resin regeneration without cartridge you will need about 2 liters of a 10% solution of non-iodized table salt. Iodized salt will poison the ion exchange resin. For a 10% solution you will need 100 grams of salt per 1 liter of water. The ion exchange resin is poured into a jar, filled with saline solution and left for 6-8 hours. The resin in the solution can be gently stirred periodically. Then the resin is washed 2-3 times with clean (filtered - prepare in advance!) water to remove excess salt and transferred back to the cartridge.
• For resin regeneration in cartridge you will need at least 5 liters of a 10% solution of non-iodized table salt. The cartridge is opened top cover(the amber resin should be visible, and not any other layers!) and carefully pour 2 liters of saline solution through the resin. It is necessary to pour carefully so that the flow of liquid does not carry resin granules over the top. After this, the cartridge is placed in a washed filter flask and filled with saline solution (it will take about 0.5 liters). The cartridge is left in this state for 8-10 hours. Then the solution is drained and 2 liters of saline solution are poured through the cartridge again. After this, it is advisable to pour 2 liters of clean (filtered - prepare in advance!) water through the cartridge to eliminate excess salt.
• After regeneration, replace the cartridge with ion exchange resin and screw on the housing.
• Using the wrench included in the filter kit, unscrew the last housing and remove the activated carbon cartridge. Rinse the cartridge and filter flask, replace and tighten the housing.
• Open the water supply tap to the filter and close the clean water tap. Check the tightness of the filter housings.
• Open the clean water tap and pour water through the filter for 2-3 minutes until the taste of salt in the water disappears.

Special cartridges (for example, cartridges for water deferrization) are regenerated differently - with solutions citric acid and drinking soda. For details of this procedure, refer to the operating instructions for the filter and cartridge. Some types of cartridges, when their resource is exhausted, are not restored or regenerated; they are replaced with new ones.

Timely replacement and regeneration of filter cartridges will always allow you to have the cleanest and highest quality drinking water.

And if you find yourself in a place where there is no filter, you can make one yourself. All the details are in the video!

Before entering the water supply, the water undergoes thorough purification. Debris, organic and insoluble mineral contaminants are removed, antibacterial treatment is carried out - in short, this is a serious and lengthy process. However, the quality of the liquid flowing from the tap sometimes leaves much to be desired, which is the reason for the growing popularity of household filters. They must be kept in order. From our article you will learn how to disassemble and clean the filter (water, carbon) for Barrier water, as well as washing it and softening it, and some others.

What kind of filter do you have at home?

In apartments and private houses, three types of filters are most often used:

• systems reverse osmosis;
• flow-through;
• jugs.

Reverse osmosis

The first type includes Geyser filters. They are good if you have to purify significant volumes of water - for example, for big family. Install such a system in a carafe, in the kitchen or bathroom.

Important! It itself is quite large, however, it does not spoil the interior at all. It is almost invisible from the outside; all large parts are put away under the sink. This is the only type of cleaning in which scale does not form on the walls of the kettle.

Its main advantage is maximum cleaning. There are, of course, disadvantages:

• high price;
• professional installation required;
• installation takes time;
• such a filter does not protect household appliances from scale;
• There is a metallic taste in the water.

Flow filters

Such a device is cheaper than a reverse osmosis system. There is no need to boil the water either. The flow filter is smaller and easy to transport. They are different sizes, and some also take a long time to install.

The most popular flow device is Aquaphor. If we talk about the disadvantages, the main one is that the body is made of transparent plastic, which quickly becomes cloudy. However, it is quite easy to find a unit of this class on sale, the installation of which will not take much time.

Jug filters

Strictly speaking, these are also flow-through ones, just because of the shape of the body they began to be classified as a separate class. These are the most popular water purification units. The device itself looks quite simple, it has two main parts:

• jug;
• replaceable cartridge.

The popularity of such devices is due to their undoubted advantages:

• do not require installation;
• You can start filtering water immediately after purchase;
• if the cartridge gets dirty, you can simply replace it;
• This filter costs much less than others;
• Design solutions are very diverse, so you can choose a jug to suit the interior of any kitchen.

The undisputed leader on the market is the Barrier water filter. In great demand Aquaphor jugs are also used. The disadvantages of these models include:

• fragile cartridge body;
• the water has a slight “swampy” smell;
• the filter does not protect against scale;
• the filter periodically becomes dirty and the water quality becomes worse;
• Over time, a coating forms on the walls of the jug itself, which not everyone can get rid of immediately.

The question of how to clean a water jug ​​from deposits so as not to damage the entire unit is at one point faced by both the owners of the Aquaphor filters and those who chose the Barrier.

What is the difference?

Household water filters differ not only in their shape and installation system, but also in what substances are used to make the cartridges:

• “Aquaphors” use a special “Aqualen” system. The cartridge is made of special fibers, which provide high-quality cleaning.
• In Barriers, the filter itself is made of ion exchange resins and activated carbon, which is a very good sorbent. In addition, during the manufacturing process Activated carbon treated with silver, which prevents the proliferation of bacteria, even if they enter this environment.

How to clean a Barrier water jug?

How can you tell if a cartridge is clogged? Very simple. The filter device begins to pass water more and more slowly. You can do it in two ways:

• replace;
• clear.

Important! Buying new elements will not be difficult - they are available in the same store where you bought the jug itself, as well as in large hypermarkets. They are inexpensive, and changing them will be much easier and faster than cleaning the Barrier water filter.

Cleaning products

But situations may arise when replacement is impossible and you have to solve the problem using the means at hand. You will need:

• baking soda;
• salt;
• soft brush;
• sharp knife.

Preparing the solution

To tidy up the pitcher filter, you need to prepare a concentrated solution of table salt. It's better if you have at home:

• pharmacy scales;
• measuring utensils.

You can do without measuring utensils, knowing approximately the volume of cans and glasses:

1. Pour 100 ml of water into a bowl.
2. Add 5 g of salt there.
3. Wait until the salt dissolves completely.

Important! The solution can be more concentrated.

Cartridge

Let's start with the cartridge. At the same time, you can process the jug itself:

1. Disconnect the cartridge from the body.
2. Wash the jug itself with baking soda - this should be done every two weeks.
3. Cut off the cap of the cartridge - you will see a mesh.
4. Rinse the mesh hot water(preferably boiled).
5. Put the cartridge in place - now it is without a cap.
6. Pass a solution of table salt through it.
7. Flush the system clean water until the salty taste disappears.

Important! After the cap is cut off, the cartridge is left without protection, so you need to pour water carefully and not allow it to directly enter the mesh.

The Barrier cartridge consists of a special resin that should not dry out. That is, there must always be water in it, otherwise the cation exchanger will lose its properties and stop purifying the water from salts. A filter with a cut off cap can be used for quite a long time.

Important! The water you use to rinse the mesh should not be too hot. It is enough if its temperature is 65-70°C.

How to clean a water jug ​​from deposits?

Despite the fact that the main element of a water purification jug is the cartridge, there is much less hassle with it than with the body. Nasty white coating It is not possible to wash it with any detergents. And there are objects and substances that should be discarded immediately:

• abrasive pastes;
• hard and melamine sponges.

Abrasive paste is absolutely useless in such a situation. Scratches will appear on the body, but the plaque will still not go away. The same applies to hard steel wool.

With melamine sponges things are a little more interesting. In principle, they wash away the plaque. But melamine itself is not at all beneficial to the body. If it enters the stomach, it causes poisoning.

Important! It is almost impossible to wash the pitcher filter so that there is no melamine left on it - there are always pores in the housing in which the smallest particles of this substance get stuck. So it's not worth the risk.

What's on hand?

When wondering how to clean a plastic jug from deposits, look at what you have at home. Even if your cabinet for household and kitchen utensils is completely empty, you will find everything you need in nearby stores and pharmacies, and at extremely low prices.

You need:

• vinegar;
• ammonia;
• lemon acid;
• formic acid.

Vinegar is irreplaceable

It's always a good idea to have a bottle of vinegar on hand. This most common substance will help out in many situations, including helping if you are thinking about how to clean a plastic water jug.

Option 1

To prepare the solution you need water and 9% vinegar:

1. Dilute water and vinegar in a 1:1 ratio.
2. Place the spout of the jug into the container with the solution.
3. Leave for 15 minutes.
4. Rinse the filter with running water.

Option 2

To prepare the solution, you can also use vinegar essence:

1. Dilute the essence in water in a ratio of 1:5.
2. Place the product in a small spray bottle.
3. Spray it along the sides of the jug.
4. Wait 15-20 minutes.
5. Wash the jug with clean water.

Important! It is better to work with the essence with gloves.

Lemon acid

It will help to get out of a difficult situation if you need to clean the Aquaphor jug ​​from limescale and citric acid. Of course, you can also use natural lemon juice, but it will cost a little more. Citric acid powder can be used either dry or dissolved in water.

Option 1:

1. Dissolve 20 g of citric acid in a glass of warm water.
2. Pour the solution into the jug so that it gets onto the contaminated areas.
3. Wait 15-20 minutes.
4. Rinse the jug thoroughly.

Option 2

For this method, the water must first be boiled and cooled slightly:

1. Pour boiled water into a jug.
2. Add a packet of citric acid there.
3. Leave it all for half an hour.
4. Drain the solution and rinse the jug.

Option 3

1. Pour dry citric acid into a jug.
2. Wet the sponge.
3. Wipe down the sides of the jug.
4. If necessary, repeat the procedure.

Ammonia

Ammonia is a wonderful remedy that can do a lot. It works wonders on calcium carbonate. True, it has a very strong and pungent smell, so it is better to use it in a ventilated area.

How to clean a water filter with this product:

1. Add 10-20 drops of ammonia to warm water.
2. Pour it all into a jug.
3. Let stand for ten minutes.
4. Pour out the solution and rinse the vessel thoroughly.

A few words about store products

The formation of limescale on the filter walls is not only your problem. Many people encounter it, so the demand for detergents that can remove such plaque is constantly growing. Manufacturers of gels and dishwashing liquids have already taken into account this need of their customers, so you can find such products on the shelves.

Important! The ingredients they use are the same vinegar, citric acid or ammonia, which can be bought separately, and much cheaper. The result will be exactly the same. True, in stores detergents fragrances are also used, and this is what often attracts buyers.

When should you clean your jug?

How long does it take to form limescale? IN different regions this happens with at different speeds. It all depends on how hard water gets into the water supply or well. A clean and sparkling jug gradually loses its transparency. It is important to catch this moment in time.

The best option is to clean the vessel about once every two weeks, unless the water is particularly hard. It's okay if you haven't noticed much change yet. Citric acid and vinegar do not harm such devices, and the procedure can take much less time than when nothing is visible through the walls.

Water filters have become a mandatory cleaning element in apartments and country houses, as well as in enterprises.

They, like any other equipment, need maintenance; in particular, the procedure for regenerating cartridges with ion exchange resin deserves special attention.

And if in single-stage devices, as well as filter attachments and jugs, the used cartridge is simply replaced with a new one, with three-stage devices everything is more complicated.

They consist of a mechanical cleaning cartridge, coal post-purification and an ion exchange resin cartridge. Due to the long service life of the device, they need to be serviced or replaced once a year.

The filter will function normally, under one condition - if regular regeneration is carried out, that is, the properties of the ion exchange resin are restored.

Resin regeneration technology - how the ion exchange resin in the filter is restored

The ion exchange resin is small balls amber, which convert magnesium and calcium ions into sodium ions. Thus, the water becomes less hard, household appliances no scale is formed.

Knowing the water hardness indicators, you can predict the approximate life of the resin cartridge. To do this, the capacity indicator is divided by the water hardness indicators, expressed in mEq/liter.

The absorption of magnesium and calcium ions is a reversible process. If there is an excess content of sodium ions, the situation will be the opposite, that is, the release of magnesium and calcium ions and the absorption of sodium ions will occur.

To avoid this, they resort to so-called regeneration, that is, restoring the functions of the ion exchange resin so that it can serve your filter for some more time.

Regular table salt will help start the regeneration process, since its effectiveness regeneration of filters with salt has long been proven in practice.

The regeneration process can be carried out many times, but the resin still gradually begins to lose its properties due to the enrichment of water with impurities, and sooner or later the ion exchange resin will have to be changed.

In general, the procedure for regeneration is as follows:

• shut off the water flow,
• turn on the tap to relieve pressure,
• remove the mechanical cleaning cartridge, wash it, as well as the flask, put it in place,

To regenerate a system without a cartridge:

• remove the ion exchange cartridge and pour the contents into a pan or other container,
• pour the resin with saline solution and leave for 6-8 hours, stirring occasionally,
• rinse the resin several times with clean water,

To regenerate a system with a cartridge, the solution is poured inside and left for 8 hours, then it is drained and the procedure is repeated;

• after which the resin must be washed with boiled water,
• install the cartridge in place,
• remove the charcoal cartridge, rinse it, put it back in place,
• Turn on the water and let it sit for a few minutes until the salty taste disappears from the water.

Baking soda and even citric acid can also be used instead of salt.

The Geyser company is one of the leaders in domestic market filters. Let's look at how to perform regeneration in three-stage models from this manufacturer.

1. Shut off the water entering the device.
2. Release the pressure by opening the tap.
3. Execute mechanical cleaning filter.
4. Prepare a 10% solution of table salt. It is better to take a larger container, as the foaming process will begin.
5. Hold the device over the sink and fill with 2 liters saline solution so that the resin does not spill out.
6. Place the cartridge back into the housing and fill 0.5 liters of solution to the top, leave for 8-10 hours.
7. Remove the device and allow the solution to drain, then refill with 2 liters of saline solution.
8. After the solution has drained, install the cartridge back into the housing.
9. Assemble the filter.
10. Turn on the water for a few minutes until the salty taste disappears from the water.

Regeneration allows you to restore the properties of B510-04 and KH cartridges.

Replacement module KH for Crystal systems

1. Turn off the water and release the pressure.
2. Remove KH by pressing the button on the device cover.
3. Assemble the included adapter for regeneration or purchase it separately.
4. Cut off the bottom of the plastic bottle and attach it to the adapter.
5. Make a solution of 2-2.5 liters of table salt.
6. Place the device with the bottle and adapter in a saucepan, and lead the adapter tube into the sink.
7. Pass the saline solution through the resin, and then 2 liters of clean water.
8. Reinstall the device.

Module B510-04 for Trio systems

1. Turn off the water supply and relieve the pressure.
2. Remove the cartridge.
3. Pour the contents into a plastic or metal container.
4. Prepare a liter salt solution and pour the contents of the cartridge, leave for 6 hours, stirring occasionally.
5. Drain the solution and rinse with boiled water. Repeat the procedure twice.
6. Place the contents back into the cartridge and replace it.
7. Don’t forget about washing the mechanical cartridge.
8. Turn on the filter for 10 minutes, after which it can be used again.

Instructions for regenerating the Aragon filter cartridge

1. Turn off the water and release the pressure.
2. Prepare a solution of 40 g of citric acid and two tablespoons of soda per liter of water. Since foaming occurs, the container for the solution should have a capacity of 1.5-2 liters. Water must be poured gradually.
3. Place the Aragon cartridge in the housing and fill it with 0.6 liters of solution. Leave for 12 hours, then remove the cartridge and drain the solution.
4. Next you will need additional processing the remaining solution. It is better to do this over the sink. The liquid is poured through the neck and left until it drains completely.
5. Then you need to rinse the device. To do this, first use 3 liters of clean water, which is poured through the neck. Then it is fixed with film and the bottom plug is removed. Holding the cartridge vertically, pour in another 3 liters of water, after which the film is removed and the plug is put in place. All you have to do is put the cartridge in its place in the filter and turn on the device for a few minutes to rinse.
