IGADEN CO.LTD. Wastewater Treatment FAQ

Even when the electrodes are contaminated, electrolysis is performed to forcibly remove the contamination by using special electronic signal based on the patented technology. For high-viscosity materials such as dairy wastewater and clay, the solid materials such as soil need to be dissolved into water to dilute it to lower the viscosity.
