ENVIOLET the State-of-the-Art Technology for “Electroless Nickel” Wastewater Treatment

Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal electric current source and, therefore, named “electroless” process. Complexing agents in the electrolytes guarantee a high metal concentration during a simultaneously high metal depletion at the diffusion layer of the plated piece.
