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

Applied Membranes cleaning cartridges are pre-filled with AMI’s specially formulated proprietary membrane cleaning chemicals for effective, fast and easy membrane cleaning. Simply exchange the pre-filter cartridge in your system with a new cleaning cartridge and run the system to flush the chemical into the membranes. Allow the solution to sit in the system overnight, then flush the chemicals to drain the next morning. We recommend a monthly cleaning to obtain optimum results.

AM-11 Acid RO membrane cleaner is specifically formulated to Calcium Carbonate, Mineral Scale, Hardness, Iron, Barium, Sulfate, and other scaling from RO membranes.

Carbonate scale fouling can be identified by the following symptoms:

  • The RO Membrane will likely exhibit low permeate flow
  • The RO Membrane will likely exhibit low salt rejection
  • The membrane may feel heavier than normal

Membrane Cleaning Cartridge Benefits

  • Clean Membranes Without Removing them from Your System
  • Reduce System Downtime

  • Prolong Membrane Life by Regular Use of Cleaning Cartridge
  • Designed to Fit Standard and Big Blue Filter Housings in 10” & 20” Lengths

Membrane Cleaning Chemicals are blended at Applied Membranes ISO 9001:2015 Certified Facilities in Vista, CA USA
