As technologies develop and populations grow, the demand for water sources increases. To keep up with such demand, innovative methods for water regeneration need to be explored. Amongst these methods is the utilization of Membrane Biological Reactors (MBRs) for wastewater treatment. MBRs combine conventional wastewater treatment technologies with a membrane, which enhances the purity of the effluent and eliminates the need for advanced treatment methods. By utilizing microfiltration or ultrafiltration, MBRs can achieve around 90% removal levels of chemical oxygen demand (COD). This work discusses membranes and factors that affect their performance. It also introduces MBRs, their significance, and the potential they offer for wastewater treatment. The study will be conducted experimentally on a lab-scale MBR to treat wastewater produced from molasses manufacturing exploring and optimizing MBRs operating parameters including influent pH, sludge concentration, and temperature. The study revealed that MBRs can effectively remove 80-90% of COD content in wastewater produced by the tobacco industry while operating at a pH of 6 -8 with an HRT of 1 day. Additionally, they are highly desirable in treating tobacco wastewater at temperatures ranging between 20 to 40 o C.
