An Electrocoagulation with Membrane Bioreactor (EC-MBR) was created in order to treat municipal wastewater and prevent membrane fouling. Experiments were carried out in a few stages to validate the new design. A laboratory-scale (EC-MBR) treating municipal wastewater operates to investigate the structure and distribution of the organic matter removal using the membrane. The study's objectives were to evaluate the organic matter (biological oxygen demand (BOD) and chemical oxygen demand (COD)) removal efficiency of Al-Hawraa wastewater, as well as its connections with statistical indicators. It was decided to sample and analyze effluent from municipal wastewater utilizing biological and chemical treatment techniques using EC-MBR with operating temperature (25 Co), pH (7-8), DO (4-6) mg/L, initial and final concentrations of BOD (184-6 mg/L) and COD (489-20 mg/L). The organic matter removal efficiency might be estimated using MLR model, according to the findings. Furthermore, the results revealed an overall reactor achieved excellent BOD and COD maximum removal efficiencies of (96.7 and 95.9 %) respectively. Finally, based on the coefficient of correlation, the MLR model by its (R2 of 98.5 %) was efficient.
