Advance Hydro Treat Electro coagulation (EC) is a well established technology for the treatment of industrial waste water without the need for process chemicals such as Ferric, PAC or polymers. It serves industries such as dairy, cheese making, metal plating, oil & gas, food processing, mining, truck & car wash, cooling water, ground remediation and potable water treatment.
A wide range of pollutants can be efficiently removed up to 98% including heavy metals, COD, BOD, suspended and colloidal solids, FOGs, bacteria, viruses, hydrocarbons, pesticides and herbicides. EC will not remove dissolved solids such as salts.
EC is a good pre treatment to membrane technologies where high quality water re-use is required.
Typical Contaminant Removal Performance using EC Technology
The removal rates for the contaminants listed below are typical and are intended to provide a guide. Most waste waters are complex products and it may only a single contaminant that needs removal to meet discharge or re-use standards. The EC technology can remove multiple contaminants from waste water or target specific elements and this is done by selection of electrode material, residence time and current density applied. It every case, it is advisable to run trials to determine the most efficient operation procedure to maximise removal rate to minimise operational costs.
The Electro Coagulation Process
Electro Coagulation is the process of applying a direct current voltage to the waste water to be treated using submerged electrodes which act as the anode and cathode. Typically, these electrodes are made from mild steel and aluminium. The current passes between the electrodes due to the conductivity of the water. The electrical current acts on the suspended particles in the water, neutralising their charges and allowing the very fine solids to precipitate and settle. The electrical current also makes the electrodes sacrificial and in doing so, they give up their metal ions into solution in water. These ions act as chemical coagulants used in DAF systems. Suspensions and emulsions are destabilised, solids coagulate and separate out and and hydrocarbons coalesce. The EC reaction time is typically between 20 and 120 seconds depending upon the contaminants being treated. The consumables are electricity and the sacrificial electrodes. Both these directly effect the EC operational cost. Energy consumption is typically 1.0 kWhr per cubic meter (1000 litres) treated with a metal electrode consumption of around 20 grammes per cubic meter treated. Sludge production in chemically treated waste water treatment carries a very significant expense in terms of the volume produced and the cost of further chemicals in its dewatering. This is because chemicals are added, often in large quantities. By comparison, EC produces significantly less sludge with much lower sludge handling costs. Unlike chemically produced sludges, EC produces a broadly neutral pH, easy to dewater and non-leaching, oxide sludge. Handling and disposal costs are much reduced.
