How does antiscalant work for a reverse osmosis water treatment application? An antiscalant is a pretreatment injected into the feedwater before the feedwater enters the RO membranes. Its presence delays the reaction between calcium magnesium and bicarbonate. This results is scale not forming as the water is being purified by the RO.

Antiscalant - an overview | ScienceDirect Topics

Rajindar Singh, in Hybrid Membrane Systems for Water Purification, 2005. Antiscalant threshold treatment. Scale inhibitors or antiscalants (A/S) are generally organic compounds containing sulphonate, phosphonate, or carboxylic acid functional groups and chelating agents such as carbon, alum, and zeolites that sequester and neutralise a particular ion which may be formed.

Scaling and antiscalants - Lenntech

Scaling means the deposition of particles on a membrane, causing it to plug. Without some means of scale inhibition, reverse osmosis (RO) membranes and flow passages within membrane elements will scale due to precipitation of sparingly soluble gas, such as calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate. Most natural waters contain relatively high concentrations of
