Abstract :
Pulp and paper mills consider as a major wastewater producer industries in order to cellulosic pollution and also consuming high amount of water during the process.The wastewater treatment process is complicated because these kinds of effluents contain suspended & colloidal impurities and color & odor; so using chemical coagulants via the Jar test can be an appropriate alternative to remove the contaminants. In this research, different concentrations of Alum, PAC and FeCl3 coagulants were tested to reduce the contamination load of the effluent from three important major parts of fiber wastewater producers; that, according to the results FeCl3 was reported as the best chemical coagulants which removed 61%, 74/05 % and 58% of the COD from the three mentioned parts effluent. Therefore, chemical treatment by using of an appropriate coagulant with the optimum concentration can perform an important role in reducing the effluent contamination load.
