Diamite™ HpH

Liquid High pH Cleaner Liquid 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.

Diamite™ HpH is a heavy duty action high pH liquid cleaner that quickly and easily mixes with water to make an easy to use cleaning solution that effectively removes a wide range of organic particulates such as silt, colloids, organics, biogrowth, and other acid-insolubles from reverse osmosis (RO) and nanofiltration (NF) membrane elements. The unique formulation helps eliminate the need for hydrogen peroxide, formaldehyde, and other membrane disinfectants as a post or pretreatment to membrane cleaning. Use alongside Diamite™ LpH for a comprehensive cleaning. If a more aggressive high pH cleaner is needed, try Diamite™ HpH Plus.

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 approx. 4 gal of water remains in each “8x40” membrane element (1 gal per each 4”x40”). Rinse completely after each cleaner.

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.
