Electro-coagulation of Bio-treated Pharmaceutical Wastewater for RO Pretreatment

Background: The advanced wastewater and water treatment by Reverse Osmosis (RO) system have almost become a common option in industries. However, achieving consistent RO feed quality the rigor of pre-treatment pose big challenge for specialists. Due to critical limiting parameters (Silica, Turbidity, BOD, Total hardness) inadequate consideration recycling plant design, Plant likely fails due scaling membrane poor productivity. This calls judicious an appropriate technology line with quality.
 Objective: objective work was study electro-coagulation pharmaceutical reference parameters.
 Materials Methods: In this paper, Electro-coagulation (EC) Bio-treated explored as Pre-treatment system. EC reactor 1m3 working volume, bipolar sacrificial Iron electrodes were used, Critical examined post treatment.
 Results: Among 14 that investigated, five namely Aluminium Al, Fe, Zinc Zn, Silica SiO2 registered reduction range 80 96 %, after electro-coagulation. Four other like Manganese Mn, Phosphate P, Magnesium Mg shown 50 80%.
 enables be operated at higher efficiency increased recovery. test before subjected regression analysis found statistical significance one P<0.01.
 Conclusion: is applicable all types (Disc & plate, conventional wound) membranes enhances life reducing fouling, maintenance, chemical cleaning, overall cost.
