Title: Water Recovery and Reuse in Electrocoat Paint Process


Water and Waste treatment costs in the Electrocoat paint process continues to rise as the cost of city water increase and water scarcity becomes more of an issue.  This presentation will provide options of Membrane Distillation and Spiral Tangential Flow membranes to recover and reuse RO Reject water and post rinse water therefore reducing overall city water usage and waste treatment.

Type: Learning Station I: Water and Paint Solids Conservation


Minimizing Water and Waste Water treatment are opportunities to reduce operational cost while at the same time being more environmentally responsible. This presentation will describe two filtration solutions to reduce the water and waste treatment costs.  The first solution will discuss the results of a pilot system used in an automotive assembly plant that resulted in the recovery of up to 90% of the waste water from body rinsing to be reused as feed to their current Reverse Osmosis (RO) system. It will highlight the potential water and operational savings while producing a water for reuse that is of higher quality than the city water currently being use to feed the RO system.  The second solution will discuss the use of Membrane Distillation and waste heat from the curing ovens to recycle and reuse RO reject water via evaporation.  It will focus on the results of a pilot study done treating RO Reject Water providing insight on the quality of the distillate water and the recovery efficiency using a Duel Tangential Flow Spiral element with an ePTFE membrane.
