Technology
Charge-Switching Technology represents a groundbreaking advancement in surface chemistry for the filtration industry. This revolutionary approach is offered through innovative ion exchange resins and membranes available in various pore sizes. Ecofilter Tek’s proprietary technology is designed to address the challenges of membrane cleaning and tackle difficult contaminants like PFAS, providing high-efficiency, regenerable solutions for industries, municipalities, and specialized sectors such as food and beverage. With a commitment to environmental responsibility and leading-edge research, Ecofilter Tek is setting new standardsin effective and eco-friendly membrane cleaning and water purification technology.



About Us
About Charge-Switching Technology
While some existing technologies address hydrophobic foulants in membrane systems, few effectively target hydrophilic foulants. Hydrophilic foulants are significantly more challenging due to their complex nature and variable charge in different environments, making it difficult to control affinity and disaffinity.

Products We Offer

AmphoPoly™ for Dairy Processors
The FDA-approved polymer additive AmphoPoly™ brings Charge-Switching Technology into membranes. When membrane manufacturers use AmphoPoly as an ingredient in the dope solutions, the casted membrane becomes a Charge-Switching Membrane. With excellent compatibility with the host polymer formula in membrane fabrication, it creates a uniform pore size with higher flux and reduces fouling issues in the dairy industry.

AmphoRes™ for PFAS Removal
AmphoRes™ is an innovative resin designed to change its charge in response to different pH levels. This unique capability allows it to capture charged contaminants like PFAS from water and release them simply by adjusting the pH. Unlike conventional resins that require salt or organic solvents (such as methanol) for regeneration, AmphoRes™ can be regenerated in a water solvent without any added chemicals—only a change in pH is needed.
