Wastewater Reduction & Dragout Recovery

The EVAPORATIVE TANK™, patented by Poly Products is the ideal solution for wastewater reduction. It is free of complicated machinery and chemistry and was originally developed as a cost-saving means of recovering valuable dragout but is now the go-to solution for many wastewater reduction projects. Our plating customers have doubled their benefits by using the EVAPORATIVE TANK™ for E.P.A. compliance and discovering dramatic savings in their waste treatment costs. The EVAPORATIVE TANK™ has also found new uses in the anodizing, painting, photographic, machining, chemical and other fields. This proven, simple and inexpensive system of recovery and reduction can pay for itself in as little as 30 days.


Evaporative Tank™

Simple and cost effective way to recover/concentrate valuable solution from rinse waters, or to minimize waste water haul off volume and lower costs:
"Why pay to HAUL WATER?"


Recover the distilled water in the Evaporator Exhaust air stream.
This will eliminate the need for make-up air, and air exhaust perming.

Heated Tank Systems

User friendly system complete with heated feed tank, pump, temperature and level control... Just add water.
