Abstract
A membrane bioreactor is actually an advanced system of conventional activated sludge system. The development of MBR systems has solved some of the problems of conventional activated sludge systems that usually exist in the secondary sedimentation unit and during the sludge separation from wastewater. In the secondary sedimentation pond of the conventional activated sludge system, gravity is used to settle the sludge. To set up the pilot membrane bioreactor and easy access to the effluent, the pilot was placed near the methanol to propylene conversion unit located in the center of the special area of ​​Petrochemical Research and Technology Company, and the effluent from tower number 351 of the unit was fed into the unit using a flexible pipe. The pilot feed tank is transferred. The effluent of Tower No. 351 used in this study has a COD of about 20,000, a TDS of about 2,500 ppm, and a turbidity of about 110 NTU, which significantly decreased after membrane treatment. It shows that its majority consists of methanol and a small amount of compounds such as dimethyl ether, acetylene, and methyl ethyl ketone were also observed.
