PolyCera®

Water Planet’s proprietary PolyCera® membranes were developed to extend the range of polymeric membrane filtration to the most challenging applications.

Our PolyCera® fabric supported flat-sheet membranes offer ceramic-like robustness, hydrophilicity and permeability at a price point that rivals commodity polymer membranes.

Our Spiral Monolith™ cross-flow, back-washable PolyCera® filtration modules offer ceramic-like fouling resistance, low differential pressure drop and extended time between cleanings.

The result is the first polymeric filtration membrane with ceramic-like filtration performance.

FEATURES

  • Super-hydrophilic material
  • High sustainable flux
  • Fouling resistant and easy to clean
  • Extreme pH, temperature and oxidant stability
  • High oil, COD/BOD, NOM and solvent tolerance
  • Surface properties inhibit biofilm formation
  • Cross-flow minimizes accumulation of fouling materials
  • Back-washing removes deposited fouling materials

BENEFITS

  • Low energy demand
  • Less process down-time
  • Maintains permeability longer (low irreversible fouling)
  • Handles the most challenging waters
  • Easy to clean
  • Reduces energy
  • Saves chemicals
  • Lowers operating cost
  • Ceramic-like performance at polymer cost

APPLICATIONS

  • Drinking water filtration and point-of-use water purification
  • Tertiary treatment of municipal wastewater for non-potable reuse
  • Conventional air and high-purity oxygen membrane bioreactors
  • Pre-filtration for brackish and ocean water desalination
  • Chemical, pharmaceutical, biotech, food and beverage process separations
  • Refining, power and other industrial water treatment/recycling/reuse
  • Critical filtration in aerospace, automotive and biomedical industries
  • Oil & gas produced water treatment (conventional, EOR, fracking, offshore)

What is PolyCera®?

PolyCera® is a new polymeric membrane material derived from a class of electrically conducting nanofiber polymers first discovered by University of California, Los Angeles (UCLA). Later, at the UCLA California NanoSystems Institute (CNSI), these novel nano-structured polymer materials were further developed into high quality membrane structures. These exotic materials exhibit unique electronic behavior that shifts from metal-like conducting to metal oxide-like semi-conducting to plastic-like insulating properties. These materials are not quite like other polymers and not quite like other metal or ceramic materials; hence we call them polymeric-ceramics or PolyCera®.

What are the benefits of PolyCera® membranes?

PolyCera® membrane materials offer a novel ceramic-like combination of extreme hydrophilicity, permeability and robustness; however, the materials (as produced by Water Planet) are easily formed into flat-sheet and hollow-fiber membranes using conventional polymeric membrane manufacturing methods and equipment. Therefore, PolyCera® membranes offer ceramic-like membrane performance with polymer-like membrane economics. This means low energy and high sustainable flux operation with long membrane lifetime, maximum system uptime, and minimal residual waste management.

What types of membranes can be made with PolyCera® inside?

In mid-2016, Water Planet will launch a flat-sheet ultrafiltration membrane product and an associated cross-flow back-washable ultrafiltration module (see below). Water Planet’s world-class membrane scientists have formulated, made and tested a wide range of membrane types from PolyCera® membrane materials. To date, PolyCera® materials have produced membranes with microfiltration, ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, pervaporation and gas separation capabilities. Water Planet is developing a number of membrane formulations in both flat-sheet and hollow-fiber form factors that it will launch in 2017 and beyond.

Is this an opportunity for you?

Does your conventional media filtration system occasionally fail, or pass contaminants that it shouldn’t?

Does your cartridge or bag filtration system need cartridges replaced too frequently?

Does your polymeric membrane system foul rapidly and need to be cleaned frequently, costing too much in system downtime?

Do your polymer membranes suffer so much irreversible fouling that your system has to be expanded to meet your throughput targets?

Do you have to replace your membranes sooner than you would like?
