Wastewaters ozonization decolorization

The main estimation results are values of ratio mineralization extent/process operating costs (ME/POC). Besides costs estimation on the basis of mineralized organic content, the cost for decolorization below visibility limit, <1 mgL that corresponds to decolorization below 1.25 % in our case, are also showed. From the point of view of the most suitable processes for decolorization of RB137 model wastewater below visibility limit, it can be seen that processes combining ozone and UV irradiation, UV/O3 and UV/O3/H2O2, are double cheaper than...
