The results of many studies in laboratory conditions show that the quality of tap water does not meet established standards. To prevent the development of diseases and extend the life of household appliances and plumbing, it is recommended to clean and soften the liquid. Often a high concentration of metals and salts is detected in tap water, which adversely affects the human body. To solve the problem, it is recommended to install ion-exchange filters in private houses or apartments.
Purpose and scope of ion-exchange filters for water treatment
The most popular and affordable way to purify and soften tap water is the use of ion-exchange filters. The method allows not only to extract, but also to retain harmful impurities.
Used in everyday life and on an industrial scale. Without the participation of ion exchange, production in the food industry, thermal and nuclear energy, non-ferrous metallurgy, wastewater treatment and in the electronic industry will be suspended. Over the past 5 years, work has been ongoing that will allow us to extract valuable components from the deep ocean.
Regular examinations allow you to identify problems or prevent their formation. In emergency situations, it is necessary to shut off the valves before and after the filter equipment, and also turn off the power supply. If you can’t fix the breakdown yourself, it is best to contact a service center.
Device and principle of operation
Ionic filters for households consist of a housing, a cartridge impregnated with ion exchange resin, switchgears, pipelines and a tank for purified water. By production, high quality materials are used, for example, steel or durable food-grade plastic.
The central part of the housing is equipped with a filtration unit, which is made of ion-exchange fiber. Behind it is a strainer that traps harmful impurities in tap water, and an ion exchanger. The task of the last working unit is to replace the ions of salts, potassium and iron with hydrogen or sodium. The housing has special outlet openings for discharging dissolved gases into the liquid to the outside.
There are different modifications of filters with different performance and power, which directly depend on the direction of movement of the regenerating stream and the filter load. Dimensions of models also depend on operating conditions and destination.
It is recommended that ion-exchange filters be installed if the mineralization of tap water reaches 100 mg of salts / 1 liter.
The most effective are considered devices with hydrogen resins. Passing through such a filter, radioactive substances and heavy metals are captured and converted into safe hydrogen. As a result of such a process, the acid-base balance of the water is changed.
Resins are substances of inorganic origin that contain a large number of pores. Available in the form of granules.
Features of operation and maintenance
To extend the life of the cleaning filter, you need to not only install it and configure it correctly, but also regularly carry out preventive measures. An integral component of the service is the timely and regular replenishment of reserves of regeneration salts, resins.With a deficiency of the active component, the entire cleaning system will not be able to work properly, and the resins will quickly become worthless.
Ion-exchange filters are often installed in country houses and cottages with an autonomous water supply system, where there is no centralized disinfection. To prevent water infection by pathogens, you need to use high-quality disinfectant chemicals.
It is also important to remember the correct disposal of waste.
Advantages and disadvantages
Ion-exchange water purification filters, like other analogues, have not only advantageous features, but also disadvantages. More about the advantages:
- Easy to install, use and maintain.
- High quality purification of tap water and its softening.
- The composition reduces the amount of salts and other harmful impurities.
Among the disadvantages are the following:
- Low rates of hydrophilicity of the resin.
- The tangible financial cost of chemical reagent recovery.
All the shortcomings in modern models are almost imperceptible, since the consumption of valuable resins is slow, and special catalysts make the process of cleaning and softening as efficient as possible.
