Water Planet’s new water filtration technology

Water Planet, a global supplier of high performance membrane-based water treatment solutions, introduces PolyCera®, a breakthrough membrane filtration technology based on advanced polymeric materials.

"PolyCera has the potential to revolutionise the membrane industry by setting a totally new benchmark for membrane performance and cost. Based on Nobel Prize winning chemistry that was further developed at UCLA and then Water Planet, PolyCera offers exceptional performance characteristics previously found only with ceramic membranes but with a dramatic economic advantage. We believe PolyCera is a true game changer in the industry," said Eric Hoek, Water Planet's CEO.

Available today as flat sheets or in Water Planet's proprietary spiral monolith elements, PolyCera membranes extend the range of polymeric membrane filtration to the most challenging applications. PolyCera membranes offer a unique ceramic-like combination of high hydrophilicity, permeability and robustness, but at a 10 to 20 times lower cost. Water Planet's spiral monolith elements leverage PolyCera's benefits in a ceramic-like cross flow, back washable filtration module. Water Planet's testing to date shows OpEx savings up to 40% relative to commodity polymer membranes and 80% relative to ceramic membranes. The result is the first commercial membrane product with ceramic-like performance and polymer-like economics.

Water Planet recently completed a six week pilot test of PolyCera BE-100-XB ultrafiltration (UF) modules to reclaim domestic wastewater for non-potable reuse at remote temporary work camps in south Texas. The testing validated that the PolyCera UF membranes were able to consistently polish wastewater to meet the standards for direct non-potable reuse with filtrate water quality always less than 1 mg/l total suspended solids (TSS), two colony forming units per 100 milliliters (CFUs/100 mL) and 0.1 nephelometric turbidity unit (NTU) turbidity. Moreover, when compared with polyvinylidene fluoride (PVDF) UF membranes, PolyCera maintained a much higher sustainable flux, and its permeability was recovered from fouling with half the backwashing and cleaning frequency.

Fouling resistant, easy to clean, highly oleophobic, and exhibiting extreme pH, temperature and oxidant stability, PolyCera BE-100-XB UF modules are ideal for a wide range of applications including tertiary treatment of municipal wastewater; high COD/BOD industrial wastewater water treatment; conventional air and high purity oxygen membrane bioreactors; chemical, pharmaceutical, biotech, and many more.
