Catalytic Passivation ®

Catalytic Passivation (CP) is a process that temporarily deadens the ionic charge on metal ions dissolved in rinse waters.

CEC discovered this quite inadvertently (like the inventor of Post-It Notes) while testing a combination of media meant to change the valence of hexavalent chrome to trivalent.  That didn’t work, but we noticed that the hexavalent chrome was a lot LESS interested in plating out after being exposed to the media we were testing.

More details on this once the ND document is signed by CEC and your company officers.

Our Clients...

“CleanEarth is unique in its approach to water/wastewater in the surface finishing industry.  Their methods have worked for us for more than 14 years in one of our plants and this year we are implementing their new MCRS method in another plant.  We have seen first-hand how they can reclaim up to 80% of our water for re-use and keep our discharge numbers well in compliance.   Jim Edwards is a true partner of ours and has gone the extra mile many times serving our needs.”
