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.
