Application of hybrid oxidative processes based on cavitation for the treatment of commercial dye industry effluents

Abstract

Highlights • Critical analysis of the hybrid processes involving ultrasound, Fenton and ozone.• Guidelines for optimum operating conditions provided for maximum benefits.• Original study on treatment of two real industrial effluents.• US-Fenton approach followed by lime treatment established as the best approach.• Use of ozone does not add much benefits to US-Fenton treatment process.
