KL™ Silica

Silica Cleaner Powder Membrane Cleaner

Even with effective pretreatment, membranes will eventually begin to scale or foul. Depending on the degree and type of fouling, generic cleaners may not fully clean off scale and foulants. Thus, residual residue could act as a hub attracting more scale and foulants resulting in a quicker fouling rates resulting in the need to clean more frequently.

King Lee offers a variety of acid and alkaline membrane cleaners to meet your specific needs and are all NSF/ANSI 60 certified for drinking water facilities. We offer our KL series powder cleaners for cost effectiveness and Diamite series liquid cleaners for ease of use.

KL™ Silica is a targeted powder cleaner that quickly and easily mixes with water to make an easy to use cleaning solution that is specifically formulated for removing aluminum, iron, and other metal silicates, including reactive and colloidal foulants and coagulated polymers. Compatible with thin film composite, cellulose acetate, and polysulfone membranes. Use alongside our Pretreat Plus® line of antiscalants for comprehensive membrane protection.

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.

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

Application
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.
