A novel design Digital Baffle Electro Catalytic Batch Oxidation Reactor (DBECB) has been conceived to upsurge the specifications of refinery wastewater (RWW), through the removal of organic pollutants by electro catalytic oxidation treatment. The modern design that eliminates organic from RWW with improving its qualities has drawn a lot of attention. These days, one of the things that the world needs are the production of clean water with strict limitations on dangerous compounds. The degree of chemical oxidation that has been used to purify this wastewater is reflected in the electro- catalytic oxidation (ECO) process .The experimentations were intended by a Response surface method experimental design comprising the consequence of the time (10-40) min, magnetite Nano particles (0.1–0.5) gm, temperature (25-60) oC, and pH (3-9) under 0.5 Amps and 200 rpm then examining the results by Minitab software of response surface method with Box Behnken design (BBD) to find the best values of these conditions (40 min,0.5 gm s of nano particle 3 pH, and 60 oC of temperature ). The organic elimination efficiency of electro catalytic oxidation was 98.2%. The electro catalytic process was suitable for organic compounds removal from refinery wastewater.
