Wastewater treatment is a crucial part that faces by every industry. Growing of demand for petroleum based products and growing of petroleum based industry, lead to the increased of wastewater from the petroleum based industry. Generally, a series of physical, chemical and biological treatment will be employed in a plant in order to treat the wastewater produced. In present study, three steps of treatment will be carrying out to treat the petroleum based wastewater. The treatment includes preliminary settling process, coagulation process and electrocoagulation process. Preliminary settling is a natural process where no additional of chemical coagulant or additive to the samples. The settling time is set to be 24 hours for all the suspended solids to settle down. Preliminary settling process showed a big removal efficiency in total suspended solid ( TSS ) of the samples. The efficiency of removal for TSS during the preliminary settling process for sample T-1630, T-2300 and PPT are 0%, 72.44% and 75.14%. However, for coagulation process, the optimum dosage of coagulant required for three different samples were determined using jar test. There was huge reduction in chemical oxygen demand ( COD ) concentration after the coagulation process. The removal efficiency achieved for the coagulation process is 27%, 63% and 65% for sample T-1630, T-2300 and PPT respectively. Although the removal efficiency is higher, however the effluent doesn’t meet the discharge standard. Advance treatment by using electrocoagulant is required. The optimum voltage is determined and all the samples are treated with applied voltage of 100 V. The efficiency of removal for COD achieved during the electrocoagulation process for sample T-1630, T-2300 and PPT is 99.75%, 98.74% and 99.62% respectively which meet the permissible level, and save to discharge to the environment.
