Robust liquid cleaner for hard to remove gypsum (calcium-sulfate) scale in easy to handle liquid form.

Effectively Removes:


Specifically formulated for gypsum fouled membranes

Dissolves several times more scale and more rapidly than the most commonly used chelating and solubilizing agents.

Gypsum targeted cleaner.

Non-toxic and enviromenttally friendly

Convenient and safe to use

Dilution Ratio

Perform a thorough low-pressure system flush. Prepare each cleaning solution as a 1:40 minxing ratio of chemical to permeate or DI water. For safety, insert the water into the tank first, followed by the chemical. if the system is not drained before cleaning , assume that approximately 4 gallons of water is present in each 8 x 40 membrane element and 1 gallon of water is present in each 4 x 40 membrane elements. Rise completely after each cleaner



Clear to Turbid, Colorless to Light Yellow Liquid

Product pH (1%):
10.4 ± 1.0


Clean each RO train when its normalized productivity has decreased by 15% from clean operation. Soak and circulation times will vary based on the condition of the membranes. Measure the conductivity of the solution in the system and make a note of the measurement before beginning the calcium sulfate cleaning. The conductivity should increase throughout the cleaning cycle.
