VITEC® SELECTION GUIDE
Antiscalants/Dispersants - Liquid
In most applications, reverse osmosis membranes and their flow passages will foul without some means of upstream scale inhibition due to precipitation of sparingly soluble salts. Common examples of scale are calcium carbonate (CaCO3), calcium sulfate (CaSO4), barium sulfate (BaSO4), and strontium sulfate (SrSO4). Less common but equally problematic are silica (SiO2) and calcium fluoride (CaF) scales.
To address membrane scaling, Avista formulates a full range of antiscalants under the Vitec® trade name.
