Development of Leachate Treatment System Prototype Integrating Electrocoagulation and Membrane Bioreactor

Abstract

Membrane bioreactor (MBR) is a technology that combines biological- activated sludge process and advanced membrane filtration. Electrocoagulation (EC) is an electrochemical technique that is extensively applied to treat landfill leachate. EC can be as a pre-treatment unit prior to the MBR in a waste water treatment process that greatly improved the treatment efficiency. In this study, the goal is to develop a leachate treatment system prototype integrating electrocoagulation and membrane bioreactor. The inlet leachate characteristics such as BOD, COD, TSS, NH3–N concentration along with the color of the leachate were fixed as the inlet of the treatment system prototype. The design parameters are used to calculate the dimensions and design of every unit of the system in order to achieve the desired treatment efficiency. The requirements of the systems are defined in details and the detailed drawings of each of the treatment units of the treatment system are portrayed. A labelled drawing of the whole system is also created to visualize the prototype in great details.
