Reverse Osmosis (RO) Antiscalant & Membrane Chemicals
Reverse osmosis (RO) water treatment protects membranes from scale, colloidal fouling and biofouling in seawater and brackish-water desalination, industrial RO and ultrapure-water systems. The program uses a continuously-dosed membrane antiscalant plus periodic acid/alkaline cleaning. VCYCLETECH manufactures the RO antiscalants and membrane cleaners below.

Dosing guidance
- Antiscalant: typically 2–6 ppm in the feed, set by the projection software for your feedwater LSI/recovery.
- Acid cleaning (low pH): for carbonate scale and metal oxides; alkaline cleaning (high pH) for organic and biofouling.
- DBNPA: intermittent dosing for biofouling control; isothiazolinones for offline preservation.

Frequently asked questions
What is an RO antiscalant?
An RO antiscalant is a continuously-dosed chemical (typically a phosphonate/polymer blend) that holds sparingly-soluble salts in solution so they do not scale the reverse-osmosis membrane, allowing higher recovery. VCYCLETECH supplies WT-0100/150/191/200 and WTASD-200.
Which antiscalant is best for seawater desalination?
Seawater RO needs a broad-spectrum antiscalant effective on carbonate and sulfate scales at high recovery; WT-200 / WTASD-200 are designed for seawater and brackish desalination. Dose per the membrane projection software.
How do you clean RO membranes?
Clean with a low-pH acid cleaner (WT-260) for carbonate/metal scale and a high-pH alkaline cleaner (WT-261) for organic and biofouling; WT-701 enables non-stop cleaning. Follow with a biocide flush where needed.
Do you ship RO chemicals worldwide with a COA?
Yes — bulk RO antiscalants and cleaners with a Certificate of Analysis, OEM/ODM packaging and worldwide shipping.
