Hardness
Scale on heating elements of household appliances, boilers and water heaters break down prematurely, soap does not foam, washing is uncomfortable. Tea and coffee prepared with hard water lose their taste and look unappetizing, especially tea.
Manganese
Black, hard-to-remove plaque on plumbing, dangerous to the human body
Permanganate oxidizability
Shows the presence of organic impurities, the water has an unpleasant color from light yellow to how did this evolve into and is a good environment for the growth and reproduction of microorganisms.
Turbidity
Shows the presence of particles in the water, such as iron or other mechanical impurities (fine sand, clay), which increases the risk of damage to equipment and faucets.
A summer resident usually faces a whole package of impurities. For example, in the Leningrad Region, the most parcoursup french post-secondary education are hardness, dissolved and/or colloidal iron, manganese, humic acids (“peat water”) and hydrogen sulfide.

“Diseases” and features of water in the country can be treated with proper analysis. Make sure clean email important indicators are measured before choosing filters.
– Replaceable (cartridge) or flushable (regenerable)
Cartridge systems restore functionality by replacing the filter element. They have a low starting price, but immediately “go off the rails” in operating costs. With significant water consumption, cartridges are changed very often. Their use is justified in rare cases: with minor water pollution, space shortage and low water consumption.
In cottage water treatment, filters are often used that can be restored by reagent or non-reagent flushing. Consider this when choosing pumping equipment and a septic tank. Systems of this type are more expensive, but much more economical to operate.
– Membrane or backfill pressure filters
Membrane systems include relatively new micro and ultrafiltration water purifiers on this market, which allow very effective treatment of a number of pollutants: colloidal iron, turbidity, microorganisms and viruses. However, the systems do not remove dissolved impurities and are still more expensive than standard solutions.
