Use of Electro-Chemical Process for Waste Sludge Generated from Moving Bed Bioreactor

Shohreh Azizi and Nomathamsaqa P. Sithebe
Abstract—The rapid population growth in South Africa has increased the requirement of waste water treatment facilities. This study was conducted to assess the moving bed bio reactor receiving from Mafikeng sewage treatment plant. The experiment was undertaken on a continue laboratory scale and analytical data was collected before and after treatment. The reduction of 83.21 COD, 87.64BOD was achieved in optimum Hydraulic retention time. The efforts also made an attention into potential technology for waste sludge reduction. The study was undertaken the use of electrochemical process as pre-treatment for waste sludge. It is observed 60% of digestion period was decreased through the Electro-chemical treatment.
Basic data obtained through the experimental research are demonstrated that the MBBR may be used in an extremely compact high-rate process (<3h total HRT) for secondary treatment process and the combination of electrochemical and aerobic digestion system is proposed to overcome all the disadvantages of aerobic and anaerobic digestion system. The complete system offers a most advance and improved sewage treatment plant.

Index Terms—Moving bed bioreactor, digestion time, electrochemical, aerobic digestion.
