This industries in terms of water and, accordingly wastewater production considered as pollutant effluent due to having various kinds of organic and mineral materials. Therefore, in order to pump it to environment or reuse it, electro coagulation method was used to remove various compounds from effluent produced in paper recycling industry. The objective of this paper is to study the possibility of produced effluent treatment in paper recycling industry using electro coagulation in order to reach necessary standards and easy implementation of wastewater treatment procedures. At first, raw effluent was analyzed after a sedimentation phase in which solid suspended substances such as fibers were separated from liquid phase. Then they were transferred to electro coagulation phase and removal efficiency of measured parameters such as COD, BOD, TSS, TDS, Conductivity, Turbidity levels were studied in electric potential range of 6-12 volt during 10, 20, and 30 minutes in three different pH (pH=7, 5.5 ,8.5 ). The results showed that increased electric potential and reaction time rise electro coagulation efficiency in that the maximum The maximum contaminant removal efficiency measures of pollutant indicators happened at potential difference of 12 volt, reaction time of 30 minutes, and pH=8.5 for COD, BOD, TSS, Turbidity, TDS and Conductivity which are reported 51.04%, 51.8%, 95.6%, 83.7%, 1.34%, and 2.69%, respectively. It is inferred that electro coagulation process enjoys appropriate efficiency to remove pollutants in paper mill effluent industry.
