Local treatment of dye-finishing works wastewater

Summary

The high efficiency of using galvanochemical method for local treatment of dyeing and finishing works wastewater is presented. The comparative analysis of galvanic coagulation and traditional coagulation with ferric salts used for azo dyes waste treatment allowed to define that the treatment efficiency in terms of the iron dosage introduced is higher in the process of galvanic coagulation than in the process of chemical coagulation. It is caused by the different mechanisms of chemical and electrochemical coagulation. The process flow chart was developed and offered for local treatment of wastewater of woolskin dyeing with direct and acid dyes.

Key words

wastewater , fur production , dyeing and finishing works , acid dye , local treatment , galvanic coagulation
