Suitability of chemical and electrocoagulation process on sugar industry wastewater treatment

摘要

Socio-economics development of any nation depends on Industrialization. With increase in number of industries needs, water is an essential requirement and added extra burden in terms of fresh water and wastewater. Among all the industries, sugar-processing industry is one of them. To fulfill the demand, appropriate technology will require otherwise with limited resources low quality of water can be used for operation. The aim of this research work is to treat the wastewater generated from sugarcane-processing industry using chemical coagulation and electrocoagulation. The aluminium salt suitability of both treatments was carried out for iron and metal electrode. A result shows 82% chemical oxygen demand and 84% color removal with iron electrode was attended at 156 A~(-2) current density, optimum pH 6 and 120 min of treatment time. Finally, settling, filtrations, X-ray diffraction and scanning electron micrograph study also conform that iron electrode is more suitable to treat sugar industry wastewater. To treat 1 m3 of wastewater, 2.0 USD will be required including all expenses.
