VERFAHREN UND VORRICHTUNG ZUR AUFBEREITUNG UND DESINFEKTION VON SCHWIMM- UND BADEBECKENWASSER UNTER VERWENDUNG VON CHLOR UND OZON

摘要

Ozone treatment of the bathing water removed from the pool (1) is conventionally effected with the very high ozone quantities of 0.5 - 1.5 g/h of ozone in 45 - 50 l/h of (pre-treated) air per 1 m3/h of raw water, and requires a specific and aerated ozonization reactor for contact times of up to 1.5 minute and a downstream ozone eliminator for reducing the ozone content of the water to below 0.02 g ozone/m3 of raw water before the latter is chlorinated and returned to the pool. This conventional ozone treatment necessitates huge investment and expenditure energy. In contrast, it is sufficient to use a proposed ozone quantity of 1% by using 1 - 1.2 g/h of ozone in 700 l/h of (untreated) air from a handy ozoniser (7) having this capacity per 100 m3 of raw water. Ozone treatment is effected without an ozone reactor and eliminator directly and under pressure in the pipe (2) of the raw water flow (Q). For this, the ozone-containing air is swirled together with a partial flow (q) of the raw water in a flow spiral (9) into an aerosol-like blended state and injected into the main flow of the raw water. The high interphases thus obtaind provide rapid ozone treatment with a quantitative ozone consumption. The uncomplicated conversion of baths having an originally purely chlorination-type operation to the ozone/chlorine treatment method of the invention enables the expenditure on chemicals to be reduced by up to 70%, while offering at the same time a significant improvement in the quality of the water.
