—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
