This study describes an experiment in which aeration and granular activated carbon (GAC) have been used for removal of dissolved organic matter, bacteria from river water. River water samples were collected from "Sorkheh Hesar Canal" east Tehran, Iran and subjected to aeration process then to granular carbon activated. The aeration process has been continuously effective during 24 hours followed by granular carbon activated filter during the treatment process. The sample treated water was taken to determine of chemical oxygen demand (COD), total organic carbon and coliform, fecal coliform tests. the spectrophotometer has been used in the laboratory experience for measure COD, total organic carbon analyzer for measure TOC and method total coliform bacteria (TC) for measure coliform, fecal coliform. The efficiency of this experiment has been investigated in the removal COD, TOC and coliform, fecal coliform significantly decreased as it reached to 77.5, 76.6, 56.7, 56.7% respectively.
