Membrane Chemicals

RO treatment chemicals help to greatly reduce deposits, impurities, and scale in your membrane’s system. Antiscalants, antifoulants and RO CIP cleaners are specially designed chemicals that keep these contaminants from attaching to the membrane surface.

Chemiequip solutions offer a full range of proven products for scale control in membrane applications.  Our offered products are designed to provide outstanding performance for severe service and general-purpose applications including the control of calcium carbonate, calcium sulphates, barium sulphates, calcium phosphates, heavy metals, silica and silicates. The key to good RO operation is a well-maintained pretreatment system.

Residual flocculants and/or coagulants from upstream treatment (cationic molecules or polyelectrolytes) can cause problems when they combine with polymeric antiscalants (anionic molecules). Avoid this problem by keeping the media filters in good condition and not overfeeding the flocculants coagulants. Antiscalent should be dosed upstream of the RO, typically before the cartridge filters. This ensures adequate mixing of the antiscalent prior to entering the RO system.


We carry a complete line of treatment products to meet the needs of our customers:

  • Versatreat series offers broad range of Antiscalants
  • Biotreat series offers membrane compatible microbicides.
  • Versaclean series offers complete CIP cleaners
  • A wide range of monitoring and control devices
  • Chemical injection system

Ready To Stand Out?

Many water utilities that could benefit from RO desalination already have conventional filtration facilities for particulate removal in place. However, water quality produced by these plants may not allow for proper downstream RO treatment. Aluminum residuals, most notably from alum coagulation, were observed to cause colloidal fouling of RO membranes through interactions with ambient silica to form aluminum silicates and antiscalent components. Therefore, selection of right antiscalent is utmost important.
