Abstract

Background & objectives: The most important organic materials are humic acid, lignins, tannins, hydrocarbons, amino acids, phenolics and fatty acids. The presence of organic compounds in water which is an important resource for the formation of trihalomethanes (THMs) and mutagenic substances and also can be used by microorganisms as carbon source call for the need to develop new systems for removing organic compounds.Materials and Methods: The water samples including raw water, the effluent after accelerator and the effluent after filtration were taken from Jalaliyeh WATER TREATMENT PLANT during 6 months; in this fashion that, 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 could 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. The accelerator had an acceptable efficiency for the elimination of TOC.Conclusions: The samples taken after raining days showed an increased amount of input organic matter, especially TOC, into the treatment plant compared to the days without rainfall.
