<p>The electrochemical sewage treatment system comprises a filter screen, macerator/cutter pump (3), electrochemical reactors (5, 7 & 9) connected to settling tanks (6, 8 & 10) at their outlet, booster pump (11) to feed treated water to filtration unit and sludge pump/dewatering pump (12) to feed the filter press/sludge drying beds (13). The electrochemical reactors comprises cell housing (5-4, 7-4 & 9-4) with inlet (5-9, 7-9 & 9-9), outlet (5-10, 7-10 & 9-10) and drain (5-6, 7-6 & 9-6) nozzles. The electrochemical reactors also consists of anodes (5-8, 7-8 & 9-8) and cathodes (5-9, 7-9 & 9-9) in bipolar/monopolar arrangement, connected in series or parallel to a DC power source to produc predetermined quality and quantity of coagulants/oxidant radicals for treating the sewage. The system is designed to work efficiently with temperature range of 8°C to 40°C, salinity of above 350 ppm, and pollutant load of upto 3000 ppm.</p> |
