PolyCera® Membranes

Water Planet’s proprietary PolyCera® membranes

Water Planet’s proprietary PolyCera® membranes were developed to extend the range of polymeric membrane filtration to the most challenging applications. PolyCera® flat-sheet membranes offer a unique ceramic-like combination of high hydrophilicity, permeability and robustness, but at a price point that rivals commodity polymer membranes. PolyCera® elements leverage the flat-sheet membrane performance in a ceramic-like cross-flow back-washable filtration module. The result is the first polymeric membrane with ceramic-like filtration performance.

Customer Feedback

Not only did Water Planet’s desalination experts come up with some great solutions for our system, they were extremely professional and provided a level of attention and quality of service that we haven’t often experienced.- Myriam Cardenas, Ground Water Reverse Osmosis Plant Manager, Santa Monica Water Resources Division
Water Planet’s qualifications in that area and the fact they can look independently at a lot of different commercial membrane technologies -- that is what attracted us to them for the membrane treatment side of things.- David Pernitsky, Senior Research Engineer Suncor Energy Inc., Calgary, Canada
Water Planet’s incredibly knowledgeable and experienced engineering staff offers a depth of knowledge unmatched in the industry, and they offer such service in the most cost-effective manner we have seen to date.- Jung-Chul Kim, Executive Vice President, R&D Division, Hyundai Engineering & Construction (HDEC)
