Reverse Osmosis Chemicals

Reverse Osmosis Chemicals are the antiscalants, dispersants and membrane cleaners that keep reverse-osmosis and nanofiltration membranes clean and efficient.

In this category: This category covers RO antiscalants and dispersants (WT-0100/150/191/200 and WTASD-200) that prevent carbonate, sulfate and silica scale at high recovery, plus acid and alkaline membrane cleaners (WT-260, WT-261) for offline cleaning. Read the RO antiscalant selection and membrane cleaning guides for dosing.

Reverse osmosis chemicals are a powerful tool for water filtration. They can remove impurities and contaminants from water, as well as reduce sediment levels in order to make the water safe to drink. These chemicals can also be used to treat wastewater or brackish water before it is sent out into the environment. The reverse osmosis process works by pushing contaminated water through a semi-permeable membrane. This membrane filters out all of the contaminants that were present in the previous state, effectively making the water clean and safe for consumption.

Reverse Osmosis Chemicals — Frequently Asked Questions (FAQ)

What chemicals are used in reverse osmosis?

RO systems use antiscalants and dispersants dosed continuously to the feed to prevent carbonate, sulfate and silica scale, and periodic acid and alkaline cleaners to remove scale, colloids, organics and biofilm from the membranes. A biocide is used where biofouling is a risk.

How do I choose an RO antiscalant?

Match the antiscalant to the scale risk in your concentrate — carbonate, sulfate or silica — and to your target recovery, and confirm the dose with a membrane projection and your feed-water analysis. Silica needs a specialty antiscalant. See our RO antiscalant selection and dosing guide.

Does VCYCLETECH manufacture RO chemicals?

Yes. VCYCLETECH supplies RO antiscalants, dispersants and acid/alkaline membrane cleaners factory-direct in China, with a COA on every batch, free samples, OEM/ODM and membrane-projection support.
