Process industries use RO to clean up water, for modern industrial applications or to convert sea water, to tidy up wastewater or to recover salts. RO Systems have low energy requirement, are compact in size, automatic, and easy maintenance. RO Membranes are contaminated with pollutants like colloids, biofilms, and organic matter. These deposit on the membrane surfaces, and consequently decrease the overall system performance. RO chemicals ensure reverse osmosis plants and desalination plants operate at peak performances.

General symptoms of contamination:

  • 10 – 15% decrease in permeate flow

  • Decrease in permeate quality (10% more salt content)

  • 10 – 15% increase in pressure gradients between the feed and concentrate  headers


RO Antiscalants

Antiscalants are unique chemical additives to prevent scale formation and to reduce the fouling rate in the RO membrane system. Alkro range of RO Antiscalants are FDA approved for non toxicity in potable water.
