Abstract

Background: The organic compounds presence in water is considered as a key resource for the formation of trihalomethanes (THMs) and mutagenic substances. Objectives: The chief motivation behind the present investigation was to examine the efficiency of Jalaliyeh water treatment plant in removal of total organic carbon (TOC). Method: The water samples including raw water, the effluent after accelerator and the effluent after filtration were taken during 6 months. Two days from each week were selected in each, of which three samples were taken from the three points mentioned above. In other words, 24 samples in each month and totally 144 samples were collected during the whole study period. The measurement of TOC was performed by means of spectrophotometer at a wavelength of 555 nm. Results: When the input TOC was at its maximum value, TOC removal efficiency was about 80% which can be increased by augmentation of the amount of coagulant substance or use of coagulant aid. The removal efficiency was declined by decreasing the concentration of TOC input. Conclusion: The accelerator had an acceptable efficiency for the elimination of TOC. The samples taken after rainy days showed an increased amount of input organic matter, especially TOC, into the treatment plant compared to the days without rainfall.
