KL Silica is a specially formulated silica targeting reverse osmosis membrane cleaners. This powder cleaner readily mixes into a solution. A low pH cleaner targeting membrane scale needs to be used prior to using KL silica.
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 are 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.


Appearance Colorless to Tan Crystals
Product pH (1%) 4.1 ± 1.1

Applications of KL™ Silica Powder Silica Cleaner
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.
