|Electrolysis Systems for Wastewater Treatment and Preservation of Water
Igaden Co., Ltd. has developed an electrolysis system called the Micro Water System which is capable of performing efficient.
water and wastewater treatment by passing a special type of AC current through the water.
The passage of electrical current in the water allows the reactions necessary for the removal of pollutants in the water without the addition of chemicals and other process input.
These reactions are the oxidation of organic matter (BOD, COD, etc),nutrient (nitrogen and phosphorus) removal, suspended solids removal by flocculation/sedimentation or, flocculation/flotation, and even destruction of pathogenic microorganisms (sterilization).
The system can adapted to a broad scope of applications, including water quality improvement of cooling tower water, industrial plant and food processing wastewater, sterilization for the recycling of hot spring water, for automobile washing wastewater recycling and for the purification of lakes and river water.
An electrolysis tank is usually installed in an existing facility such as water storage tanks and settling tanks.
The installation cost of the system (which includes the Micro Water system and electrolysis tank) will run up to roughly \2,500,000.
The maintenance time and cost will depend on water quality, but the maintenance requirement will generally be once in 3 months to one year. Changing of electrodes once a year is sufficient.
Thus, the maintenance cost will be comparatively low.
