Abstract

This research investigated the design of a conventional drinking water treatment plant for a surface water source to serve urban area in Homs city. The treated water comes from a surface water; Orontes River with values of pH, electrical conductivity, temperature and hardness that meet the Syrian Standards No. 25. The average total suspended solids were 330 mg/L, the turbidity was between 20 and 200 Nephalometric Turbidity Unite (NTU), and the color was 50º. Therefore, the water had to undergo chemical treatment. The design flow was approximately 0.6 m3/h. The treatment steps were recommended based on the water properties as follows: A mechanical rapid mixer for coagulation, aluminum sulfate was used; the dose was determined by jar test, a flocculation tank, a rectangular sedimentation tank, followed by rapid sand filters, the final stage is disinfection using chlorine.
