Ozonation of Urban Waste Water in Tourist Zone

摘要

Ozone dose is adjusted as a function of the treated flow so that the residual ozone is maintained between 0.2 and 0.6 g/m3. Total coliform count is then reduced from 107to 103/ml. In the treated effluent, entero-viruses have not been found in 20 liters volume samples. Color and chemical oxygen demand are also reduced.
