EFFECT OF SPACING OF DIFFERENT TYPES OF ELECTRODES IN THE ELECTROCOAGULATION PROCESS

Abstract

: Electrocoagulation technology is an executive method of using electrical power to rebound and flocculate pollutants without needing to add coagulations. This treatment process can remove small particles since the direct current is applied, and set them into motion. Also, electrocoagulation could decrease the remainder of waste production. This research concentrates on the use of electrocoagulation depending on a scaled open channel physical model using installed different types of electrodes such as Stainless Steel, Steel, and Aluminum to reduce the contaminants. The used electrodes have been installed parallel to the water flow direction in the stream, with a variation of four values of volts used in the experiment with the different spacing between electrodes 1cm, 2cm. The selected inflow water is Q=10 l/hr for the physical model has quality indicators limits such as COD, BOD, Total Coliform, and Fecal Coliform. The outcomes of the paper present that the best removal efficiencies depend on electro-coagulation by using Stainless Steel sheets and the spacing between these sheets equal 2cm, this distance reduces the current density Which leads to reducing the cost, also the water produced is suitable for agricultural and industrial use.
