Introducing: Zwitterionic Reverse Osmosis Elements

The First RO Membrane that Reduces Cleaning Frequency by up to 90%

ZwitterCo developed the industry’s very first fouling-immune brackish water reverse osmosis element with a lower rate of fouling and the possibility of restoring performance using only a water flush. Lower your operating costs with as much as a 90% reduction in cleaning frequency.

Fouling Immunity 

The most frequent killers of membranes are performance loss due to fouling and/or performance loss from frequent alkaline cleaning. ZwitterCo RO membrane addresses these two issues by being able to fully recover performance and reduce cleaning by up to 90%. Because ZwitterCo RO elements are exposed to less frequent cleanings, they will last longer (perhaps significantly longer) than conventional BWRO elements.

ZwitterCo RO membranes offer:

  • Significantly longer run time between required maintenance
  • Full performance restoration
  • Possibility to recover performance using only a water flush
  • Longer membrane life
