Merit Partnership Case Studies: Chapter 04: Reducing Rinse Water Use with Conductivity Control Systems
Chapter Abstract: This is clip 4 of 5 for this video. Electroplating is historically a water intensive industry. Artistic Plating and Metal Finishing of Anaheim, California was selected as the implementation site for the conductivity control systems pollution prevention project. Dirty rinse water from their process lines is sent to an onsite water treatment system before being discharged into the sewer. Metal salts in the rinse water caused by Dragout increases the conductivity of the water. The rinse tanks had originally been designed as continuous flow through rinses. With a conductivity control system in place, water only flows through the rinse tanks when it is needed to maintain water quality. When the conductivity of the water reaches a set point, clean rinse water is allowed to flow into the tank. When the conductivity lowers to acceptable levels, the flow of water is stopped.
