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.

Our Vitec antiscalants inhibit scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec products help extend system run times, reduce cleaning frequency and increase the productive life of RO elements. The Vitec 8000 series antiscalants are part of our Green Chemicals line, specially formulated for sites with discharge restrictions.
