Evaluation of Van Muradiye wastewater treatment plant using response surface method

Water demand is increasing and water resources are rapidly depleting because of reasons such as population growth, technological development, rising living standards, and industrial development. For this reason, wastewater production has increased in the world and in our country. The uncontrolled discharge of these wastewaters into nature causes environmental problems. Treatment of wastewater is an important factor for the protection of water resources, and physical, chemical, biological and advanced biological treatment methods are widely applied today. In this study, wastewater samples will be taken from different points determined in the wastewater treatment plant located in Muradiye district of Van; parameters such as pH, dissolved oxygen, conductivity, Suspended Solids (SSM), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), nitrogen and phosphorus will be measured and the performance of the wastewater treatment plant will be evaluated in the light of these data. By looking at the parameter values, it will be determined whether it complies with the discharge standards of the Water Pollution Control Regulation (WCR). In addition, the performance of the wastewater treatment plant will be evaluated using CCD (Central Composite Design) and the optimization of pollution parameters will be done. In the evaluation of the performance of the treatment plant, the parameters such as mixed liquid suspended solids (MLSS), mixed liquid volatile suspended solids (MLVSS), sludge volume index (SVI), oxidation reduction potential (ORP) will be evaluated by drawing time-dependent graphs in the samples taken from the aeration tank. Thanks to the process optimization carried out in this study, it will be possible to solve the operational problems of Van Muradiye Domestic Wastewater Treatment Plant operated by Vaski General Directorate.
