“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.”

– Industry Expert, identity available under NDA

Our Premium Bioinspired Nano Ceramic specialized 50 nanometer Ultrafiltration (UF) Membranes are able 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 176 F) and pH ranges (pH 2 – 12). Comparison flux data of zUF50 membranes versus PAN specialty and PS commodity for a variety of wastewaters is shown in graphs below.

zUF50 membranes outperform other membranes due to our coatings and as evidenced by the wetting data below.

Wetting Data

zUF50 membranes are commercially tested, proven, and are in use for oil and gas produced wastewater treatment, laundry and agricultural wastewater treatment. See our case studies. See Market Applications for more potential applications for the zUF50 membranes.
