“There are a handful of companies that claim to have developed an antifouling polymeric membrane technology for difficult to treat wastewaters. After evaluating and comparing with ceramic membranes, we have chosen to work with zNano because their product performs well and their team is supportive.”

Products & Services
zUF50 Membranes (4” and 8” elements)
zNano’s Premium Bioinspired Nano Ceramic specialty 100 nm polymeric Ultrafiltration (UF) Membranes have ceramic like properties. This enables them to treat some of the most difficult-to-treat wastewaters where oil and grease exceed 100 ppm. zNano’s bioinspired membranes offer: higher permeability, maintained rejection, high operating temperature (up to 176F) and pH ranges (pH2-12).
Bioinspired Nano Ceramic Membrane Coatings as a Service
For membrane manufacturers and large OEMs, zNano provides hydrophilic anti fouling bioinspired nano ceramic coatings as a service.
Anti fouling can enable functionality when treating high concentration organic feed streams.
For ultrafiltration membranes, permeability can increase as much as 100%.
For thin film composite nanofiltration and reverse osmosis membranes, coatings can be optimized to slightly increase flux (+30%) or slightly increase rejection (+0.1%).
We take the nastiest, most difficult-to-treat waters, such as produced water, and restore it to environmental standards which allow for reintroduction back into the environment or easily polished for other uses.
Before and After
Our membranes are currently being used to treat produced water with high concentrations of oil for overboarding.
“biomimetic filters mimic the structure of naturally filtering cellular water membranes”
“zNano is comprised of a world class team of scientists and engineers who are a critical asset to any project including advanced water treat technologies, my specific association with them.”
zNano’s bio-inspired nanoceramic technology combines surface science, material science, and chemistry, to create a coating that mimics a cellular lipid bilayer, the natural cells barrier to water passage. zNano applies our technology to water purification membranes (ultrafiltration, nanofiltration and reverse osmosis) to enhance its properties like improve fouling resistance, improve recovery after CIP (cleaning in place), increase permeability (A – water permeability value), and maintain rejection of oil and grease (O&G).
