New Product Announcement: Ultrafiltration Membranes
Global coatings manufacturer PPG recently introduced its ultrafiltration (UF) membrane and filter elements to remove oil and other contaminants from water and wastewater.
The company states in their news release that the new UF membrane is an addition to its line of microfiltration (MF) membranes and filter elements for industrial process water and wastewater disposal and reuse.
The membrane reportedly includes an antifouling treatment technology and is superhydrophilic, or attracted to water, which could keep trace amounts of oil, grease and other tough-to-filter contaminants from fouling the membranes and filter elements.
Additionally, the new product can reportedly prolong the service life of membranes and cut down expenses with lower maintenance and replacement needs.
“Our antifouling treatment represents a significant technical advancement with potential benefits in multiple industries,” said Lisa Walters, PPG filtration segment manager, Specialty Coatings and Materials.
“The traditional belief is that membranes are not well-suited for removing oil and grease because of their tendency to foul. PPG filtration membranes have an exceptional ability to separate emulsified contaminants from water.”
PPG states that its MF and UF membranes can separate oil, grease and emulsified contaminants from higher volumes of industrial process water, potentially reducing the number of filters and the amount of floor space needed to recover the water for reuse.
“The ability to clean and reuse industrial process water is beneficial in so many ways, not just to the companies that recapture this valued resource, but also for the environment by reducing demands and stress on freshwater supplies,” said Walters.
Potential applications for PPG filtration membranes reportedly include industrial process water and wastewater, oil and gas, automotive and industrial paint lines, and graywater treatment.
