Abstract

Considering the surface water resource as one of the main potable water supplies and the application of chlorine as one of the main disinfectant drinking water has increased the rate of Disinfection by products (DBPS) formationthat One of the main group of DBPS are THMS compounds that are carcinogen compounds. Objective of this survey the determination of THMS concentration in Sanandaj water treatment and ralation between THMS formation with free residual chlorine and organic matter. Sampling was done on ten steps, at various stages of Sanandaj water treatment during the year, and 50 samples were analyzed and results.THMS were measured with gas chromatography. The THMS concentration in input raw water (less than15μg/l) and output (20μg/l) that was lower than the international standard .This study showed that a positive relation is between THMS formation with free residual chlorine and organic matter. After coagulation, flocculation unit is the lowest THMS. Which represents the performance of this unit focuses on eliminating THMS. THMS is the highest level of the final chlorination..
