Membranes that organics don't stick to.

We use revolutionary zwitterionic chemistry to build membranes that stick to water molecules instead of the organic compounds they filter out, preventing permanent organic fouling.

Zwitterionic membranes operate beyond the limits of traditional filtration, unlocking new ways of managing industrial wastewater and process streams including:

  • Treating complex wastewater for compliant discharge
  • Purifying effluents for reuse
  • Maximize efficiency in food processing

“Conventional anti-fouling membranes still only have modest organic foulant limits, however, we’ve found ZwitterCo membranes can we handle a lot higher organic levels. We see no drop in performance in these [high fouling] streams and the anti-fouling characteristics remain exceptional.”
