Product data sheet

Features

A stronger high pH cleaner for especially difficult to remove organic material.

Aggressive, high-performance broad-spectrum cleaner compatible with RO, NF, and UF membranes from all major manufacturers.
Effectively removes silt, colloids, organics, biogrowth, and other alkali-soluble foulants.
Liquid formulation ensures ease and safety of mixing and includes a highly effective sanitizing agent.

Dilution ratio

Perform a thorough low-pressure system flush. Prepare each cleaning solution as a 1:40 mixing ratio of neat cleaner to final prepared cleaning solution by filling the CIP tank with the appropriate volume of permeate or DI water, then adding chemical while mixing or circulating in the tank. If the system is undrained post-flush, assume approximately 4 gal of water remains in each 8"x40" membrane element (1 gal per each 4"x40"). Rinse completely after each cleaner.

Specs

Appearance: Light yellow to orange liquid
Product pH (1%): 12.5 ± 0.5

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.
