The Use & Benefits of Ro Antiscalant in RO Plant

Author: Shubham Karnani

Water is one of the important resources, and ensuring its purity and availability is crucial for both industrial and domestic use.

Reverse Osmosis Technology plays a vital role in the removal of impurities such as salts, minerals, and other contaminants from water for various applications, including drinking water, industrial processes, and boiler water treatment. The RO membrane is the heart of the RO System designed with a dense, thin, and semi-permeable layer that allows water molecules to pass through while rejecting dissolved solids and other contaminants. The RO Membrane operates under high pressure and requires continuous cleaning and maintenance to prevent fouling and scaling.

What Causes the formation of scales in RO membranes?

The level of hardness salts present in the feed water is the foremost reason. When such feed water passes through the RO Membrane, the concentration of these salts gets precipitated over the surface of the membrane. Overtime deposition of such salts from scales. This scale formation reduces the effectiveness of the membrane, which ultimately decreases the flow rate of water. In smaller systems, scale formation can be prevented by the exchange softening process but in larger systems, it becomes expensive.

RO Antiscalant – Cost Effective Solution

RO Antiscalant known as scale inhibitors are essential components in water treatment processes, these are designed to prevent precipitation and accumulation of scale-forming minerals such as calcium carbonate and calcium sulphate, on the surface of RO Membranes. It becomes essential to maintain the long-term performance and reliability of the RO membrane.

How it works?

RO Antiscalant works by altering the chemical environment of the feed water in a way that inhibits the formation and growth of scale-forming minerals. They work by interfering with the crystallization process of scale-forming minerals, keeping them in suspension and preventing them from adhering to the membrane surface.

Selecting the appropriate RO antiscalant is essential to maximize its benefits. Chemtex manufactures its antiscalant for Reverse Osmosis (RO) Systems, depending upon the type of membrane, quality of feed water, and rate of product recovery.

  • High pH RO antiscalant inhibits scales and disperses colloidal particles in cellulose acetate and thin-film membrane separation systems, stable over a wide range of supersaturated salt solutions.
  • Neutral RO antiscalant reduces membrane fouling within separation systems, effectively controlling inorganic salts, metal hydroxides, and colloids in RO feed water.
  • Low pH RO antiscalant eliminates inorganic scales in multiple application areas. It stabilizes metal ions to prevent metal oxide precipitation and disperses silt and clay particles.

Key Features & Benefits

  • Excellent scale inhibition
  • Reduced membrane cleaning
  • Compatible with all types of membranes
  • Eco Friendly and Biodegradable
  • Maintain the correct pH levels
  • High recovery rate with low dosage
