Water is the basis of life, one cannot but agree with this. But what if the water does not meet sanitary and hygienic standards? We present to your attention modern home water purification systems.

Choosing a filter

Cleaning methods

Mechanical filtration is the easiest way to clean. Water passes through a kind of sieve that traps insoluble impurities, sand, rust. The smaller the size of the holes, the higher the degree of cleaning, but the lower the productivity and resource. Modern ultra-filters are able to detain even bacteria. Ion exchange replaces harmful particles with useful ones. “Unworthy” ions are removed from the water and remain in the filter material. Excess calcium and magnesium are perfectly removed - reducing water hardness. The main advantage of this method is the possibility of repeated use of the filter medium. Sorption is the removal of harmful substances by absorption. Well removes chlorine, improves the taste of water, partially kills bacteria. However, the resource of the sorbent is limited. All organic substances, heavy metal ions are removed from the water by the electrochemical method, all viruses, bacteria and microorganisms die. The advantage of the method is environmental friendliness, the absence of replaceable cartridges, the productivity is 50-70 liters per hour. You can disinfect water with the help of chemicals - antiseptics. But after their application, it is necessary to purify the water already from chemistry. Water undergoes deep purification by passing through a semi-permeable membrane. To increase the life of the membrane in domestic systems, mechanical and carbon filters are installed. Good filters use a combination of methods. The shortcomings of some are offset by the virtues of others.

Filter types

Pressure filters are mounted on a faucet or cut into a pipe. Purifying from undissolved impurities - sand, silt, rust, they protect household appliances and plumbing. Substances dissolved in water pass freely through a mechanical filter, which means that additional purification of water to drinking quality is required. Filters that are attached to the faucet for the duration of filtration, or stationary ones that are built into the water supply, help. The stationary filter is very convenient - it is hidden under the sink, and a separate tap appears on the sink - only for clean water: for drinking and cooking. And tap water is also suitable for washing dishes. Such filters have the largest resource (4000-12000 liters of water) and the highest filtration rate (1.5-3 liters per minute). The disadvantage of such installations is a rather high price. In non-pressure jug-type filters, water is filtered by gravity. This is the most familiar and easy-to-use type of filter, which is useful both at home and in the country. Manufacturers of pitcher filters produce several types of cartridges for them with different filtering properties - for soft, hard water, there are bactericidal cartridges. The performance of filter jars is from 20 g to 500 g per minute. Pitchers differ in volume (from 1-2 liters to 4-5 liters), they have a different resource of replaceable cartridges (from 100 to 500 liters). Lovers of outdoor recreation can choose bactericidal filters for water purification in field conditions. These are handy and compact devices.
