NITRITES AND THEIR IMPACT ON EFFLUENT CHLORINATION

Thus, a nitrite concentration of only 10 mg/L will exert a chlorine demand of about 50 mg/L. It has been shown, however, that when chlorine is added to effluents with nitrites and with a high concentration of ammonium ion (>20 mg/L), the chlorine reacts preferentially with the ammonium ion forming chloramines (Phoenix 1995).

chlorine as disinfectant for water - Lenntech

Which chlorine concentration is applied? Chlorine gas can be obtained as fluid gas in 10 bar pressure vessels. It is highly water soluble (3 L chlorine/ 1 L water). To kill bacteria little chlorine is required; about 0,2-0,4 mg/L. the concentrations of chlorine added to the water are usually higher, because of the chlorine enquiry of the water.
