Removal of organic load and suspended solids from water by electrocoagulation metho
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
Electrocoagulation (EC) is an electrochemical technique involving in-situ generation of coagulation agents from sacrificial anodes by type of aluminium and iron. In the present study EC has been evaluated as a treatment technology for organic load and suspended solids removal from a real wastewater proceeded from pulp and paper industry, which was characterized by high content of organic load and suspended solids. The efficiency of the electrocoagulation process was assessed by monitoring Chemical Oxygen Demand (COD) and suspended solids (s.s.) parameters. Laboratory- scale experiments were conducted with aluminum anode to assess its efficiency under galvanostatic regime. To establish the optimum operational parameter selected as current density, the electrolysis was carried out at 50, 100 and 200 Am-2. The electrocoagulation process performance was assessed based on the efficiencies of COD and s.s. removal correlated with the specific electrical energy consumption. Applying EC processallowed to achieve the COD removal efficiencies ranged between 83.80 and 94.00 % and s.s. removal efficiencies between 87.77 and 95.47 %
