RO Antiscalant: Selection & Dosing Guide
An RO antiscalant is selected to match the feedwater's scaling tendency — carbonate, sulfate, silica — and dosed (typically 2–6 ppm) according to the membrane projection software for your recovery.
Selection
Match the antiscalant to the dominant scale: broad-spectrum WT-200 / WTASD-200 for seawater and high sulfate; WT-0100/WT-150 for brackish water.
Dosing
Use the projection software to set ppm from feed LSI/recovery; verify with the membrane maker's limits. Full program: RO treatment.

Which antiscalant is best for seawater RO?
A broad-spectrum antiscalant for carbonate and sulfate scale at high recovery, such as WT-200 / WTASD-200.
