Biological treatment in treatment of domestic wastewater of business problems investigation of Van province

Many different processes and technologies are used for the treatment of domestic wastewater. As the domestic wastewater characteristics differ, it is important to optimize the existing processes or determine the appropriate treatment technology for that area. The problems in wastewater treatment plants generally arise from mechanical, electrical, construction and project faults as well as poor feasibility studies and type project applications. Due to the mistakes made during the design, construction and operation phases of the treatment plants, the desired effluent quality cannot be obtained or the operating costs are high. In this study, biological treatment methods applied in wastewater treatment plants are examined and their application areas are mentioned. In addition, treatment plants; construction problems, biological treatment characteristics, populations they serve and their general characteristics such as their capacities and operational problems and solutions are evaluated. Wastewater treatment plants with different processes, Scaffold biological wastewater treatment plant (classical activated sludge), Edremit, Gevaş, Başkale, Çelebibağ and Gölağzı advanced biological wastewater treatment plants (long aerated activated sludge) based on treatment efficiency, operating conditions and receiving environment characteristics The aim of this study is to determine the process appropriate for the receiving environment, climate conditions and geographical location of Van province.
