KL™ LpH

Powder Low pH Cleaner 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™ LpH is a heavy duty action low pH powder cleaner that quickly and easily mixes with water to make an easy-to-use cleaning solution that effectively removes a wide range of inorganic scale such as metal hydroxides, carbonates, phosphates and inorganic membrane foulants from reverse osmosis (RO), nanofiltration (NF), and ultafiltration (UF) membrane elements. Use alongside KL™ HpH for a comprehensive cleaning. If a more aggressive low pH cleaner is needed, try Diamite™ LpH Plus.
