Reverse Osmosis technology provides an efficient and reliable method for purifying water for various purposes). It can remove impurities such as salts, minerals, and other contaminants as well as microbial contaminants from the Membrane. Water molecules pass through RO membranes despite dissolved solids and other contaminants being rejected by the membrane. RO membranes are basically thin, dense, and semi-permeable membranes. However, the major significant challenge in Reverse Osmosis System is Scaling.
Why does it happen?
The formation of scales on the RO (Reverse Osmosis) membrane is primarily caused by the presence of certain dissolved minerals and salts in feed water. Scale refers to the accumulation of mineral deposits, such as calcium carbonate, calcium sulphate, and silica which can severely impact the efficiency and the lifespan of the RO membrane.
RO Membrane scaling may lead to cause
- Excessive Energy Consumption
- Membrane gets clogged
- Minimizes the quality of production
Every System needs maintenance, care, and cleaning. Cleaning of the membrane is important for maintaining an RO System. To address the issue of scaling in RO systems, RO antiscalants are commonly used. The RO antiscalant work by inhibiting the formation and growth of scale deposits on the membrane surface.
RO Antiscalant – Cost Effective Solution
RO Antiscalant is a chemical additive specifically designed to prevent scale formation on the surface of the RO Membrane. These inhibitors create a protective layer on the surface and act as a safeguard against the accumulation of minerals, such as calcium carbonate, calcium sulfate, and silica that can precipitate and hinder the performance of the system. They prevent the RO membranes from scaling and subsequent corrosion, keeping the capacity close to design. It becomes essential to maintain the long-term performance and reliability of the RO membrane.
The Benefits of Using RO Antiscalant
- Scale Prevention: The primary function of RO antiscalant is to inhibit scale formation, It creates a protective layer on the membrane surface, attracting and binding to the mineral ions which help to prevent their precipitation and the subsequent formation of scale deposits on the membrane.
- Increase the Lifespan of Membrane: RO Antiscalant offers a prolonged lifespanof the RO Membrane through prevention of scale.
- Increases efficiency and productivity of the RO plant: Scale deposition can reduce the performance and efficiency of the RO System, by eliminating scale formation, it helps to ensure the system operates at its optimal efficiency, delivering the desired water quantity while minimizing energy consumption.
- Cost Savings: The prevention of scale formation through the use of RO antiscalant can result in cost savings for the RO membrane plant. By effectively preventing scale, antiscalant helps reduce operational and maintenance expenses, making it a cost-effective solution in the long run.
Chemtex Specialty Limited manufactures a range of high-quality antiscalant chemicals designed to prevent scale formation, it depends upon the type of membrane, quality of feed water, and rate of product recovery.
We are licensed under category 99 of the FSSAI (Substances Added to Foods) for Chemtex Antiscalant Chemicals. The antiscalant disperses existing metal oxides and hydroxides, silt, and clay particles by stabilizing metal ions and preventing their precipitation.
Our Ranges are:
High pH RO antiscalant: These antiscalants are designed to effectively inhibit scale formation under alkaline conditions. It is able to inhibit and disperse colloidal particles in cellulose acetate and thin-film membrane separation systems.
Low pH RO antiscalants: These antiscalants are designed to combat scale formation under acidic conditions. It eliminates inorganic scales in multiple application areas.
Neutral RO antiscalant – It is a specifically formulated solution that effectively prevents scale formation without affecting the pH balance of the system.
