RO SURFACTANT CLEANER 25 LTR

Directions for use

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 down time 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.

NALFLEET™ RO Surfactant Cleaner conforms to the requirements of NSF/ANSI Standard 60 – Drinking Water Treatment Chemicals – Health Effects.

Dosing and Control
NALFLEET™ RO Surfactant 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. NALFLEET™ RO Surfactant Cleaner cleaning solutions are made at 1.0 – 2.0% (by weight) with chlorine-free product water and sodium hydroxide addition to give a pH of 10.5 – 11.0.
