What Is RO Antiscalant?

Antiscalant chemicals are used to prevent the scaling & fouling of the RO membranes. Scale may consist of mineral fouling such as calcium sulfate, calcium carbonate, barium sulfate, silica, calcium fluoride, and strontium sulfate. The Antiscalant dosing should be done before reaching the RO membranes to break up sulfate precipitates, calcium carbonate, and other mineral fouling.

Antiscalant chemical is used to process very poor quality feed water at very high rates of recovery. When used properly, Antiscalant extends the time between membrane cleanings from a few weeks to years in some cases. Without Antiscalant, membrane systems would not be as successful serving the water treatment industry.
