Specifications for RO Membrane Cleaning Cartridges How to Clean RO Membranes using Cleaning Cartridges

To prevent biological growth, it is recommended that systems and membranes preserved during storage, shipping, or system shutdowns.  AMI’s membrane and system preserving cartridges are loaded with a pre-measured amount of our proprietary membrane preservative AM-88 to preserve system and membranes in-place for extended periods of system shut-down. Simply exchange the pre-filter cartridge in your system with a preservative cartridge and run the system to flush the chemical into the membranes and system lines to prepare the system for shutdown.

Membrane and System Preservative Cartridge Benefits

  • Preserve membrane and system before shut-down to protect from biological fouling.
  • Pre-loaded cartridges allow for fast and easy introduction of the preservative into the membranes and system without removing the elements.

Membrane Preservative is blended at Applied Membranes ISO 9001:2015 Certified Facilities in Vista, CA USA
