About Us

At Ecofilter Tek, we believe the biggest gap in the filtration market is the lack of sophisticated surface chemistry solutions.

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.

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.
