In this project, a treatment plant with a capacity of 4 cubic meters per second is designed to reduce water turbidity. In this proposed process, direct filtration is used. The treated water is collected in 4 concrete tanks with a volume of 87500 cubic meters each and finally pumped from there to the special petrochemical economic zone. The project includes a catchment tank, clarifier, sand filter, chemical and executive preparation buildings, pumping station, workshop, substation and control room.
