Project TitleAntifouling Membranes for Water Purification
Track Code5344
Short Description

A membrane technology was developed that solves the build-up challenges of existing technologies for ultrafiltration and reverse or forward osmosis (RO/FO) filtering of seawater and wastewater.

Abstract

A membrane technology was developed that solves the build-up challenges of existing technologies for ultrafiltration and reverse or forward osmosis (RO/FO) filtering of seawater and wastewater. Current RO/FO technologies often suffer from membrane bio-fouling, which negatively impacts water throughput and membrane life. The Cornell invention is an antifouling membrane technology suitable for ultrafiltration and RO/FO membranes. The approach involves modified RO/FO thin-film composite membranes with antimicrobial nanoparticles deposited on the surface. The surface modification creates a uniform, durable coating and results in charged groups that prevent microbial build-up, while maintaining permeability and salt rejection.

 

Potential Applications:

  • Desalination
  • Wastewater treatment and pre-treatment

 

Advantages:

  • Mitigates fouling of ultrafiltration and RO/FO membranes to maintain throughput and membrane life
  • Low cost potential
