Electro Coagulation Process
ELECTRO COAGULATION (EC) TECHNOLOGY FOR TREATMENT OF DOMESTIC & INDUSTRIAL SEWAGE & EFFLUENT
Demineralised water (also known as Deionised water), is water that has had its mineral ions removed. As majority of water impurities are dissolved salts, deionization produces high purity water that is generally similar to distilled water, and this process is quick and without scale build up. De-mineralization technology is the proven process for treatment of water. A DM plant produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. Demineralised Water System finds wide application in the field of steam, power, process, and cooling.
COAGULATION
As previously defined, the electrical current and trace dissolved metals from the electrolytic cell plates cause the suspended matter to come together, forming larger particles.
FLOATATION
During the reaction in the cell housing, oxygen bubbles are formed and attached to the coagulated matter, causing it to rise to the surface in the separation tank where it is removed and transferred to the sludge holding tank. The air bubble separates from the separated contaminant allowing it to sink to the bottom of the sludge holding tank where it stays until it is properly disposed of by the customer.

PROCESS FLOW
Lifting of raw sewage from equalization tank / collection tank through Pump & Send it to Electro Coagulation (EC) reaction chamber.
Aluminium Cell base EC reactor applied control electrical field in to the raw sewage water & current is applied to the electrolytic cell plates causing trace amounts of the plate material to be dissolved into the water. Electrical current and trace dissolved metals from the electrolytic cell plates, cause suspended matter to come together, forming larger particles.
After EC reactor process , water along with suspended matter will go to ozonation tank where adequate quantity of ozone will be deposing in to the Ozone tank for the purposes of disinfection (primary use) and also decontamination or remediation. Ozone is a very strong oxidant and virucide. Ozone is more effective than chlorine in destroying viruses and bacteria. The ozonation process utilizes a short contact time (approximately 10 to 30 minutes). There are no harmful residuals that need to be removed after ozonation because ozone decomposes rapidly. After ozonation, there is no re-growth of microorganisms, except for those protected by the particulates in the wastewater stream. Ozonation elevates the dissolved oxygen (DO) concentration of the effluent. The increase in DO can eliminate the need for re-aeration and also raise the level of DO in the receiving stream. Not Require any aeration. Remove heavy bacteria load in water. Remove contamination in water.
After the ozonation process , water will be transferred to Sludge separation tank/tube settler. The air bubble separates from the separated contaminant allowing it to sink to the bottom of the sludge holding tank where it stays until it is properly disposed of through sludge filter/bag filter.
After separation of sludge , treated water send to IMT (Inter Mediate Tank ) where treated water will have vey negligible amount TSS, will be lifted through pump & send it to Carbon filter for final polishing of water.
After Carbon Filter, treated water will be collected to collection tank for further line of action.
