  • Less expensive than traditional ceramic membranes

Contact Water Planet today to find out how PolyCera membranes can enable you to address even the most challenging water.


 On this page of our website, we show links to news about our clients.  The first link, below, features our client Water Planet, a water technology company funded by Kevin Costner, Bluestem Ventures and Air Liquide.  The story on a Bakersfield CBS affiliate is about Water Planet’s work cleaning dirty water produced in California oil and gas drilling so that it can be recycled for use in agriculture.  Not mentioned specifically in the news clip, Water Planet has a couple of very significant innovations – a software based filtration optimization system (Intelliflux™) and a novel membrane material with special properties (PolyCera®).
