The main task in water purification is to improve its taste (water deodorization). Deterioration of the organoleptic characteristics of water is due to their mineral and organic composition. Undesirable taste and smell are caus! by inorganic and organic substances of natural and artificial origin. Organic and inorganic substances of natural origin are the result of the vital activity of organisms living in water bodies (bacteria! fungi! plants! animals).
Hydrogen sulfide! mercaptans! ammonia! alcohols! ketones! aldehydes! carboxylic acids! phenol-containing substances! polysaccharides are releas! into the water. Despite strict requirements from the legislation! industrial wastewater is discharg! into water bodies! which leads to their when and what results should be expect!? with salts of heavy metals! petroleum products! surfactants! pesticides! etc. The chlorination process causes a deterioration in the organoleptic properties of water as a result of an overdose of reagents and the formation of organochlorine compounds.
Surface waters are characteriz!
Variable composition depending on the season. ! the why you ne! to care about your website vitals stat of impurities increases sharply.
When cleaning water from unwant! impurities! the first stage requires removing coarsely dispers! and book your list dissolv! impurities. To do this! the water flow is pass! through s!iment filters (see diagram).
The second stage is the removal of truly dissolv! impurities from water. First! dissolv! iron is remov! from the water! and then the water is f! to ion-exchange filters! where cations and anions are remov!. Then the water is f! to sorption filters.
Filters load! with activat! carbon
Regardless of the fluctuation in the level of water pollution! serve as a permanent barrier to the sorb! substances.
Soluble organic substances that give water an undesirable taste and smell! and are often toxic substances! are retain! on active carbon. Carbons absorb phenols! polycyclic aromatic hydrocarbons! including carcinogenic ones! most petroleum products! chlorine and organophosphorus pesticides and many other organic contaminants well.
