Product information
This product supersedes product no: PERMACLEAN, PC-33
NALFLEET™ RO Alkaline Cleaner is also effective in removing iron oxides and hydroxides as well as calcium carbonate, though RO Mild Acid Cleaner is preferred for these foulants. NALFLEET™ RO Alkaline Cleaner is highly effective when used in combination with high pH detergent cleaners such as NALFLEET™ RO Surfactant Cleaner to help remove organic substances and microbial slimes.
During normal operation, RO membranes can become fouled, which greatly reduces the efficiency of the system. Deposits build up on the membrane until they cause a reduction in permeate flow and loss in salt rejection. The effects of fouling can lead to poor water quality, loss in production, unscheduled downtime and membrane replacement. A regular maintenance and cleaning program can provide return on investment (ROI) results ranging from 100 to 250 % by maintaining low pump output pressures and extending the membrane’s life.
Elements should be cleaned whenever the normalized permeate flow rate or salt rejection decreases by 10-15 % or the differential pressure increases by 10-15 % from the original baseline data.

Directions for use
NALFLEET™ RO Alkaline Cleaner should be fed via a closed feed system. A closed feed system is defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere except through normal venting or pressure relief devices.
Cleaning solutions should be made up with chlorine-free water to give a 2.0 – 2.5 % solution of NALFLEET™ Alkaline Cleaner. It is sometimes possible to monitor the progress of membrane cleaning by the “pick-up” of hardness salts in the cleaning solution.
** Storage Instructions: RO alkaline Cleaner should be stored at temperature above 15 °C. Below 15 °C the product can form precipitation.
