Abstract |
This installation consists of a holding tank that feeds rinse tank effluent to a stacked membrane filter, the control system and the filter itself. The filter concentrates and removes metal salts, returning them directly to the plating tank, while effluent contaminated with a low concentration of nickel, brighteners and other plating chemicals goes to wastewater treatment. The second technology consists of an electrolytic recovery unit followed by a fluidized bed ion exchange unit. Nickel recovered by the two units is sent to a refiner for recovery. A third nickel management technology has been installed in a shop in North Carolina that is the largest manufacturer of nickel plated keys in the country. Again, work volume is similar to the preceeding shops. In this technology, a spray rinse over the plating bath followed by two still rinses that are returned to the plating bath create a closed loop nickel plating system. The water level and nickel concentration in the plating bath are maintained by an evaporator, while a carbon filter removes any contaminants. |
