Today, the condition of wastewater treatment equipment in cities leaves much to be desired. Many systems require reconstruction and modernization, as they are outdated and inefficient. All of this negatively affects the quality of water supplied to consumers through the water supply system.
Mainline filtration devices for technical softening used in everyday life are often purchased by households to protect certain household appliances that constantly use water from the tap from scale deposits on the walls, all kinds of precipitation and contamination. This type of filter usually includes water softening units for washing machines, water heating boilers, dishwashers, …
Many of us ask the question, whether it is necessary to defend the tap water and how much this method helps to purify water. If we take cold artesian water from lime beds as an example, it is very hard and contains a lot of calcium. In the process of settling at room temperature, the …
Home water treatment should include deferrization if the concentration of iron exceeds the standard 0.3 mg/l. Deferrization of water Well and well water is often full of iron. It is not safe for your health and can promote blood diseases and cause allergic reactions. Laundry washed in water with a high concentration of iron stains, …
The reverse osmosis unit requires regular maintenance to maintain system reliability and water purification quality.
Many people have probably seen in foreign movies how a certain hero simply pours himself a glass of tap water to quench his thirst. Can I use tap water at home and as drinking water? To find out the quality of such water and require a chemical analysis. Sometimes after you take a shower your …
Reverse osmosis is a process in which water (solvent) passes under pressure through a semi-permeable membrane, becoming less concentrated and losing dissolved substances in itself. The reverse osmosis process has been in use since the 1970s. Originally it was used for seawater desalination, but today it is used for various purposes: preparation of feed water …
Hard water is water with a high content of dissolved minerals, namely calcium and magnesium (although iron, aluminum, and manganese can also be found in certain areas). The chemical nature of hard water is due to the content of cations with a +2 charge, especially Ca 2+ and Mg 2+. These ions are not a …
Iron in water can exist in different states, namely : Divalent iron – this can be any compounds involving iron in divalent form. For example, in open sources it can be humic acid iron compounds, organic-mineral complexes, iron sulfate FeSO4, iron sulfide FeS, suspensions of iron hydroxide Fe(OH)2. In underground springs, iron bicarbonate Fe(HCO3)2. Trivalent …
The reverse osmosis water purification system is a complex of filters and membranes. Passing through the system, the water gradually gets rid of organic and mechanical impurities, chemical compounds. Reverse osmosis without boiling frees water from pathogenic microflora, lime sediment, flavors and odors. The output is drinking water that is comparable to distilled water. What …
