System of cleaning of the pool

Within many decades the technology of water purification in pools essentially did not change. As a rule, for pools it is everywhere used systems which consist of the sandy filter with manual or automatic washing and the dosing systems for introduction of chemical reagents (chlorine the containing disinfectants, coagulants, regulators rn, algitsida, cleaners etc.) . The majority of these reagents are far unsafe for the person. The wrong application or technological failures at control and dispensing of these reagents can bear direct health hazard of the person. At the same time quality of water of pools leaves much to be desired. External signs of the bad pool is the turbidity of water and a pungent smell of chlorine. Reddening of eyes and dryness of skin are the reason of excessive dispensing of reagents and first of all chlorine which is added for water disinfecting. If for a water filtration in the pool the sandy filter is installed, then chlorine and chlorine-containing disinfecting substances should be added in large numbers as sandy filters are not effective for water purification from bacteria at all. Moreover, sandy filling often grows and is an additional source of various bacteria. Fear of infectious infection or fungal disease is the main reason for refusal of a large number of people of visit of swimming pools. Besides unpleasant impact on the person, chlorine in excess quantities interacts with various organic substances that leads to education in water of highly toxic, cancerogenic hlorogranichesky connections (chlormethanes, the polychlorinated diphenyls etc.).
