Comparative Study of the Degradation of Real Dyestuff Effluents by Three Kinds of Electrolysis Methods

Abstract:

A comparative study of three kinds of electrolysis methods: indirect electro-oxidation, electro-flocculation and electro-Fenton, as pre-treatment processes for a real dyestuff wastewater with high salinity and unbiodegradable organics were investigated. The efficiency of each method was evaluated according to the reduction levels of COD and toxicity, as well as biodegradability improvement. The results indicate electro-Fenton process as the most efficient pre-treatment method for improving biodegradability, reducing toxicity, and removing organic pollutants from dyestuff wastewater.
