How to restore a cartridge with ion exchange resin. Aquaphor crystal water filter - “don’t be lazy to measure the water hardness before buying this “miracle”. Is it easy to regenerate the anti-scale cartridge? my experience". Filter restoration process

Filtration devices are present in many houses and apartments, providing their owners with clean, safe water. In household filters for water softening, special modules with ion exchange resin, which usually exhaust their resource 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:

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.
While pressing and holding the button on the filter cover, disconnect the module by unscrewing it counterclockwise.
Firmly insert the adapter into the KN module.
Screw the cut bottle to the adapter.
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.
Pour the solution through the module, being careful not to allow any sediment to get into it.
After spilling saline solution You need to pass about another 2.5 liters of clean boiled water through the module.
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.

Regeneration of Aquaphor KN cartridge

The softening cartridge will have to be regenerated quite often. Here is a table of the restoration frequency of the replaceable KN module from the instructions from the Aquaphor company.

The hardness of tap water in Sevastopol averages 4.5 meq/l, according to data published by Sevgorvodokanal.

Therefore, cartridge regeneration must be done every 200-250 liters.

How to regenerate an Aquaphor KN cartridge with a solution of table salt:

Turn off the water in front of the water purifier and open the clean water tap to relieve pressure.
Pressing all the way and holding the locking button on the water purifier cover, unscrew the used module counterclockwise.
Assemble and connect the adapter for regeneration to the KH module
Firmly insert the adapter into the KN module
Screw a standard plastic bottle with the bottom cut off (in the form of a funnel) to the adapter.
Prepare 2-2.5 liters of table salt solution (approximately 300 g/l non-iodized salt) using boiled water.
Install the module with plastic bottle vertically (for example, in a jar). Direct the plastic conductor tube into the sink.
Pour the solution through the module. Make sure that no sediment left when the salt dissolves gets into the module.
After saline solution pour 2.5 liters of boiled water through the module.
Return the module to the water purifier.

A drinking water filter is no longer a rarity today. 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, a standard strong-acid ion-exchange gel-type cation exchange resin is most often used. 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 of the 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 cartridge with activated carbon. 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 baking 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!

At a depth of 2.5 kilometers, scientists discovered water that is 2.6 billion years old. Thanks to deep isolation, the underground source has remained completely intact. But experts do not recommend drinking from this amazing reservoir: it is clean and transparent in appearance, ancient water may contain hazardous substances and bacteria.

Polypropylene module or as we all used to call it EFG. These modules are designed to filter water from mechanical impurities. Most buyers doubt its need, much less use it as a stand-alone module. Let's try to figure it out. Is this module needed or not?

Water (H2O) is hydrogen oxide, widely distributed in nature. It is well known that water is the source of life. Without it, no living organism can exist. For normal life, each person needs about 3 liters of water per day, which he consumes in the form of drinking and food. Well-being and health depend on the quality of this water.

Pathogens infectious diseases enter water sources with the excrement of sick people through sewers, with the drains of infectious diseases hospitals, veterinary hospitals, and the corpses of sick animals. These are diseases such as intestinal infections, cholera, typhoid, hepatitis, dysentery, leptospirosis, brucellosis, tularemia, helminthiases (worms) and many others. Blue-green algae, which release hepato- and neurotoxins into the water, are also dangerous. Children, the sick and the elderly are at greatest risk of infection. For them, even so-called opportunistic microbes (usually not causing diseases) are extremely dangerous.

Important aspects of water quality are total salinity and hardness. These indicators affect the organoleptic properties of drinking water and, in the case of high hardness, the suitability of water for use for domestic purposes.
Total Soluble Solids.
Total salt content includes inorganic salts(mainly calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and small amounts of organic substances that dissolve in water. OSRTV in drinking water may be due to natural sources, wastewater, urban stormwater runoff or discharge, and industrial wastewater.

In fact, water does not obey any laws of physics. She has her own laws, created by nature only for her. When water is cooled below +4 °C, it does not compress, but expands.

1. Do not use the first 10 - 13 liters of water for food (stationary systems, "Modern" educational institution), 3 - 5 liters (jugs), immediately after installing the water purifier cartridges.
2. If the water purifier is not used for long periods of time, drain the first few liters of water. If the water purifier (stationary) will not be used for a long time (more than two days), turn off the water supply to it.
3. To ensure High Quality filtered water, change filter cartridges promptly.
4. Do not use for filtering hot water water purifiers, if they are not intended for this purpose. In case of accidental contact with hot water, drain 3 - 5 liters cold water(do not use as food).
5. If the source water has high hardness (more than 7 meq/l), then after softening it may have a slightly salty taste. This occurs due to the exchange of calcium ions for sodium ions, is not a malfunction of the water purifier and does not harm your health.
6. Purified water cannot be stored for long periods of time. Fresh, filtered water should be used throughout the day.
7. The replaceable module in the filter jug from Aquaphor does not require constant contact with water during use (unlike cartridges from Barrier, Brita, Anna, Geyser), i.e. It can be kept with or without water.
If you need a break in using the filter for a long period of up to two weeks, then a replacement module from Aquaphor (B100 - 5, 100 - 6, 100 - 7, 100 - 8, 100 - 3, 100 - 4, B 300, etc. ) can be removed from the jug and wrapped in plastic bag and put it in the refrigerator, in the compartment for storing vegetables for this time, then, when necessary, insert it into the jug, drain the first two funnels of filtered water and continue using it.
8. The shelf life of Aquaphor cartridges before use is 3 years at temperatures from + 5 to + 40 ° C without breaking the packaging.
Do not allow the water purifier to be knocked or dropped.
Do not place near heating devices.
Avoid freezing. Keep the water purifier away from direct sunlight.
