Reverse Osmosis (RO) Antiscalant & Membrane Chemicals
TL;DR 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鈥? 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.

To narrow the available grades, share the industry, water or process conditions, treatment objective, current program, required quantity, packaging and destination. Representative sample results are helpful when performance depends on site water chemistry.
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?
To narrow the available grades, share the industry, water or process conditions, treatment objective, current program, required quantity, packaging and destination. Representative sample results are helpful when performance depends on site water chemistry.
