[Information] Water treatment methods for nitrogen components (ammonium) and zinc in plating wastewater.

Ammonia stripping + coagulation treatment + discontinuous point chlorine treatment using hypochlorous acid

This document presents case studies on the water treatment methods for nitrogen components (ammonium) and zinc, which are present in high concentrations in plating wastewater. Since ammonium and zinc are found in high concentrations in plating wastewater, an effective method is to reduce ammonia using ammonia stripping, which volatilizes it as ammonia gas and then treats zinc through coagulation and sedimentation. In cases where ammonia is at a significantly high concentration, it is anticipated that ammonia may remain even after ammonia stripping treatment. Therefore, a combined method is employed, which includes discontinuous point chlorine treatment using hypochlorous acid after the coagulation treatment, achieving treatment to a level suitable for river discharge. The PDF document provides detailed information on the treatment flow. *For more details, please refer to the PDF document or feel free to contact us.*
