The device in order to maintain the water of swimming pools chlorinated for reduce the emissions of nitrogen trichloride and chlorohalogenes in the air of the swimming pool and reduce the formation of an organometallic - chlorine in the water of swimming pools

摘要

A method for chlorinating swimming pool water while reducing release of nitrogen trichloride and chloro-halogenated gases into the atmosphere and the formation of organochlorine compounds in the pool water comprises injecting CO2 gas under pressure upstream of the filter, installing UV irradiation chambers downstream of the filter and injecting chlorine into the recirculating water. A method for maintaining the quality of the water in swimming pools and baths treated by chlorination to reduce the emission of nitrogen trichloride and chloro-halogenated gases into the atmosphere of the pool and to reduce the formation of organochlorine compounds in the pool water, comprises injecting CO2 gas under pressure into the water upstream of the filter(s); interposing one or more chambers for irradiation of the water with bactericidal UV with a wavelength of 253.7 nm downstream of the filter(s); and injecting chlorine into the water to be returned to the pool downstream from the irradiation chamber(s).
