Features of water filters

Pure water is the key to good health and beautiful appearance. Nowadays, a truly pure liquid is becoming a big shortage. There are a lot of harmful substances in tap liquids, which give the water an unpleasant taste and smell. In addition, tap water contains a large amount of harmful impurities that adversely affect human health. Harmful impurities contribute to the development of various diseases, cause exacerbation of chronic diseases, negatively affect the entire state of the body. Today, water purification filters help to completely purify water at home.

When choosing a filter for cleaning, it is necessary to determine, first of all, the level of pollution of tap water. Today there is a wide variety of different models - these are simple, inexpensive jugs, as well as reverse osmosis systems that are able to completely remove harmful substances, and household filters for purifying water in an apartment, mobile and compact. One of the simplest and most convenient types is filter jugs. Flow models are reliable and efficient systems. Such models are able to purify liquid of any degree of pollution and make such a liquid tasty and healthy. When the liquid passes through them, passing through several degrees of purification, the water becomes absolutely pure, tasty and healthy. This filter system can be conveniently installed under the sink. It is completely invisible and does not take up space in the kitchen. The visible presence of this filter in the kitchen is a small faucet in the area of ​​the sink, the shape of which can be chosen depending on the interior. The shape of the faucet can be of various configurations, ranging from classic shapes to the most modern shapes. Such a system is capable of passing any amount of water.

As a rule, the water passing through the filter goes through several stages of purification, which determine the replaceable cartridges. Cartridges are made of a specific material and have a specific function. The polypropylene cartridge is used to trap mechanical impurities such as grease, sand, rust, etc. that get into the liquid after passing through the water pipes. The ion-exchange cartridge contained in the filter is able to soften the liquid using special resins. The flow filters also contain a carbon cartridge that retains heavy metals, organic and inorganic compounds such as chlorine, ozone and phenol.

The reverse osmosis system that exists in stationary filter systems occupies a special place among the models for cleaning. The filter element in such filters is a semi-permeable membrane. Reverse osmosis systems have been used in submarine water treatment systems since the 1970s. These water purification systems were used to produce fresh water from sea water in submarines. Over time, they began to produce household models. Today, reverse osmosis filters are considered the best in this field.

In the process of passing through the filter of the reverse osmosis system, the water is initially subjected to preliminary purification, which occurs with the help of cartridges. Then, passing through the membrane, the water is divided into two parts. The first part of the water, which has been purified, accumulates in a special tank, through which it then flows in purified form for use. The other, contaminated part of the water, consisting of filtered compounds, is discharged into the sewer. In this filter, water purification occurs at the molecular level. The membrane built into the filter is capable of passing only water, oxygen and trace elements safe for health. When purifying water, this filter is able to remove up to 98% of all substances contained in the water.
