The MicroCel zero discharge system is an automatic, on-board, closed-loop, fully integrated waste water treatment system.  When using solvents that separate from water, the zero discharge system automatically removes the solvents from the used rinse water and returns the wash solvent to the wash reservoir for reuse.  The used rinse water is then processed through the four-stage purification process, including microbial control, 5-micron filtration, carbon adsorption, and mixed bed deionizing resin to restore the rinse water to is original purity level.
