Robust cleaner for hard to remove silica scale in powder form.

Effectively Removes:


Specifically formulated for removing aluminum, iron, and other metal silicates.

Removes reactive and colloidal silicate foulants and coagulated polymers.

Targeted performance silica cleaner.

Powder formulation makes shipping and handling more efficient.

Dilution Ratio

Prepare each cleaning solution using a ratio of 1 lb of cleaning powder to 10 gallons of permeate or DI water. If the system is not drained before cleaning, assume that approximately 4 gallons of water is present in each 8”x40 membrane element and 1 gallon of water is present in each 4”x40” membrane element after a thorough system flush.



Colorless to Tan Crystals

Product pH (1%):
4.1 ± 1.1


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. Monitoring pH during cleaning and documenting results for each step will help empirically fine-tune your procedure.
