Pesticides Removal from wastewater by Electrocoagulation Technique Using Stainless Steel (Ss-Ss) Plate Electrodes.

Today hazardous waste management has become one of the most challenging tasks to this technological world because tons of organic pollutants including various carcinogens are being exposed without the sufficient treatment. Electrocoagulation (EC) due to some advantages over chemical coagulation is becoming a popular process to be used for treatment of organic pollutants especially when pollutants are toxic. The aim of this work is to investigate the effect of  current density, reaction time, initial concentration, addition of sodium chloride and magnetic field intensity oriented in two different directions on both removal efficiency of methomyl and the energy consumption. Current density 20 mA/cm2 was recommended from economic point of view as well as 3.5 g/L NaCl concentration. Magnetic field in parallel direction effects positive in contrary of perpendicular direction where the removal efficiency reached to 100% in 45 min when 0.041T was applied in a parallel direction.
