Hatco systems provides classical physico-chemical treatment processes that are used for the wastewater treatment is filtration, air stripping, ion-exchange, chemical precipitation, chemical oxidation, carbon adsorption, ultrafiltration, reverse osmosis, electrodialysis, volatilization and gas stripping. One of the advanced electrochemical technology based technique is the electrocoagulation process.
Electrocoagulation (EC), the passing of electric current through water, has proven very effective in the removal of contaminants from water. Electrocoagulation systems have been in existence for many years (Dietrich, patented, 1906) using a variety of anode and cathode geometries, including plates, balls, fluidized bed spheres, wire mesh, rods and tubes.
In the past few decades it has been used for the treatment for the water containing foodstuff wastes, oil wastes, dyes, suspended particles, chemical and mechanical polishing waste, organic matter from landfill leachates, defluorination of water, synthetic detergent effluents, mine wastes and heavy metal-containing solution.
Electrocoagulation has become one of the affordable wastewater treatment processes around the world by reducing electricity consumption and miniaturization of the needed power supplies.
Electrocoagulation offers an alternative to the use of metal salts or polymers and polyelectrolyte addition for breaking stable emulsions and suspensions. EC removes metals, colloidal solids and particles and soluble inorganic pollutants from aqueous media by introducing highly charged polymeric metal hydroxide species.
Electrocoagulation uses a proprietary treatment chamber and electricity to treat a wide range of differing waste streams containing heavy metals, virus, bacteria, pesticides, arsenic, MTBE, cyanide, Biochemical oxygen demand (BOD), Total dissolved solids (TDS), and Total suspended solids (TSS). It is used to treat municipal, industrial and commercial wastewater.
Electrocoagulation reactor is made up of an electrolytic cell with one anode and one cathode. EC system essentially consists of pairs of conductive metal plates in parallel, which act as monopolar electrodes.
