Diamite™ LpH Plus

Low 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™ LpH Plus is a performance low pH liquid cleaner that quickly and easily mixes with water to make an easy to use cleaning solution that effectively removes highly scaled membranes, specifically formulated for carbonate scale. It also removes a wide range of inorganic scale such as metal hydroxides, carbonates, fluorides, phosphates, and inorganic membrane foulants from reverse osmosis (RO), nanofiltration (NF), and ultafiltration (UF) membrane elements. Use alongside Diamite™ HpH for a comprehensive cleaning.

Features

  • Aggressive broad spectrum performance cleaner.
  • Specifically formulated for hard to remove carbonate scale.
  • Ideal for the removal of acid soluble scale including iron, calcium carbonate and metal oxides.
  • Liquid formulation for ease and safety of mixing.
  • Compatible with RO, NF, and UF membranes from all major manufacturers.
  • Certified under NSF/ANSI Standard 60 for drinking water production.

Applications

Classics: Broad spectrum cleaners designed to cover a range of scales and foulants.

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 8”x40” membrane element (1 gal per each 4”x40”). Rinse completely after each cleaner.

Specs
Appearance: Clear, Light Yellow Liquid
Product pH(1%): ≤ 2.5

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.

Packaging
