Synthesis of PAN/GO membrane for shrimp pond wastewater treatment in a bioreactor via Persian Gulf microalgae Dunaliella salina

In this work, a membrane bioreactor with hollow fiber PAN/GO nanocomposite was studied for the treatment of Persian Gulf shrimp pond wastewater. Dunaliella salina has been used for better treatment and the formation of sludge mass in a shorter period of treatment in the MBR system. Additionally, GO nanoparticles were used in order to improve the hydrophilicity of the membranes. To evaluate the treated wastewater, TP, TN, TSS, NTU, BOD, COD, EC were assessed. The addition of GO nanoparticles caused to decrease the contact angle. Also, the removal percentage of COD and BOD was over ۹۰% for membranes with graphene oxide nanoparticles. It can be concluded that the use of Dunaliella salina microalgae and membrane with polymer PAN/GO in the MBR in process is a suitable method for wastewater treatment.
