Abstract

The effect of ultrasound (US) and electrode material on electrochemical treatment of industrial wastewater was studied. Sam-ples were taken from three industries i.e. battery, ghee and tannery. Treatment efficiency was monitored by comparing the results of elec-trochemical and sonoelectrochemical processes in terms of metals and chemical oxygen demand COD removal. Experiments were per-formed in ultrasonic bath. In sonoelectrochemical process concentration of Pb decreased from 11.5 to 0.6 ppm at 80 kHz form battery industry. Similarly about 95 % removal of Cr (III) was observed from tannery wastewater using lead cathode. Titanium anode was found best counter electrode in metals removing. High COD removal was obtained by using steel anode at 80 kHz. Use of ultrasound is very ef-fective in removing heavy metals and organic pollutants from industrial wastewater.
