Treatment of Electroplating Wastewater by Adsorption Technique
Treatment of Electroplating Wastewater by Adsorption Technique

The wastewater in the equalization cum storage tank contains CN-, which is firstly made alkaline with Sodium hydroxide and then Sodium hypochlorite is added for cyanide destruction. As a result, cyanide is converted to cyanate and finally to CO2 and N2, when pH is raised to above 7.5. The primary treated wastewater from both the tanks is mixed
