A Prototype of Industrial Waste Water Treatment Using Electrocoagulation

Abstract

This paper proposes a construct of electrocoagulation waste water treatment system. The system consists of reactor tank, skimmer, cyclone tank and sediment tank. Waste water is feed into reactor tank. The electrochemical reaction is made emulsification to waste water. The contaminants are removed from waste water and can be divided to two kinds: light weight suspensions be floating up and another be sediment. The flocculants are skim out and the sediments are pumped out to sludge container. An electrical power which feed to electro-coagulation procedure is controlled by microcontroller. The user can be adjusted for suitable with waste water loaded. The input of waste water and output of sediments are controlled by PLC. The results, when operate with industrial waste water, can be treat by 30 m3/day rates and the controlled parameter value: pH, BOD, Oil & Grease, COD, SS, TDS, and Ni are not exceed than the standard limit. The advantages of this system are consume small area and low power consumption.
