DECOMPOSITION OF DYES IN THE WASTE-WATER BY ELECTROLYTIC METHOD

Extensive use of dyes in various fields has led to water pollution pro blem when these are discharged into waste waters. The physico-chemical and biological methods alone cannot remove dyes in a satisfactory man ner and in certain cases the combination of the approaches also is not feasible. It is, however, possible to reduce the dye content of the w ater by electrolytic decomposition. Accordingly an electrolytic cell w as designed and used for the treatment of the waste water containing d yes. The dye content of the waste water was reduced appreciably.
