发明名称 METHOD OF PROCESSING WATER, IN PARTICULAR BATH WATER
摘要 Described is a method of processing water passed round in a closed cycle, in particular bath water. The water is treated with ozone (11), filtered (9) and reacted with a flocculent (8) and an ozone-reducing halogen. In order to maintain the quality of the recycled water at an acceptable level and, in particular, to keep the thihalomethane (THM) content below 0.01 mg/l, the incor- poration of additives is controlled as a function of the redox pot- ential (6) of the untreated water. The ratio of the quantity of floc- culent to that of halogen is preferably constant, this being most simply achieved by mixing these substance beforehand. Particu- larly suitable is a mixture of one part of sodium bromide (NaBr) and five to twenty parts of a commercially available polyalumini- um chloride (PAC) flocculent with an alumina (Al2O3) content of about 10 %.
