The used data recorded during 2008, with the contents of pollutants out of the water treatment plant. Chemical laboratory to determine which are the following: acidity; alkalinity; pH-number; oxidation-reduction potential (rH values <15 we are dealing with a corresponding reduction state of anaerobic fermentation and for rH> 25 we are dealing with aerobic oxidation state corresponding reduction) chlorides and sulphides; nitrates (RNO 2) and nitrites (RNO 3); dissolved oxygen (which show the overall degree of water pollution with organic substances); biochemical oxygen demand BOD (mg/dm 3); COD (Chemical Oxygen Demand in mg/dm 3); TOC (Total Organic Carbon); CTO (total oxygen consumption); nitrogen as free ammonia (15 ÷ 50mg/dm 3) in the form of organic nitrogen, nitrite and nitrate.
