Designed for use in new and existing TRU TEMP® low-temperature black oxide finishing lines, NEAR-ZERO™ Water Recycler allows user to recycle and re-use process rinse water by filtering out free and emulsified oil and detergent residues, reducing rinse water consumption up to 99%. System maintains rinse water pH at near neutral level for continual reuse. After about 1 month, filter media is changed, all 3 rinse tanks are changed and refilled with clean water, and cycle starts over.
