ARIES offers a complete range of membrane treatment chemicals, including:
Aries Chemical is one of the leading RO plant antiscalant chemical supplier India, offering a complete line of membrane protection products in our ISO-certified laboratory in Vadodara, Gujarat. As one of the reliable water treatment chemical manufacturers India, we provide antiscalant chemical for RO plant applications, including low pH, high silica, membrane antiscalant, membrane cleaners, and biocides for industrial and commercial RO plants in Gujarat.
Our reverse osmosis antiscalant chemicals are well-suited for high TDS, silica-laden feed water and difficult water conditions. The result is consistent performance and longer membrane life.
Why Do RO Membranes Fail?
RO membranes in industries are continually exposed to salts, suspended solids, and bacteria. Without an appropriate antiscalant for RO membrane, these membranes start to lose performance early.
Scaling is most common because calcium carbonate, calcium sulphate, and silica deposit on the membrane surface and prevent the flow of permeate. Biofouling occurs when microorganisms form a biofilm layer, which restricts flow and contaminates treated water.
Organic fouling caused by iron, manganese, and colloidal particles hinders flow and causes high pressure drop.
If the membrane is not dosed appropriately with reverse osmosis antiscalant chemicals, life can drop from 5–7 years to less than 2 years without the need for frequent cleaning, downtime and operating expenses.
With the right antiscalant chemical, you can avoid all three. Here is the Aries Chemical RO treatment line.
Our RO antiscalant chemical products are formulated to perform reliably in a wide range of feedwater conditions and in various industrial applications.
Low pH RO Antiscalant
RO antiscalant prevents calcium carbonate and sulphate scale in feed water with high TDS. Works well between pH 6.0 and 8.5 in industrial RO systems.
High Silica RO Antiscalant
This reverse osmosis antiscalant is designed to inhibit silica scaling at LSI levels up to +3.0. It is ideal for use in borewells and industrial water where silica fouling is a problem.
RO Membrane Cleaner (Alkaline)
Alkaline cleaner designed to remove organic fouling, biofilm, and biological deposits. It is used during CIP processes to restore membrane performance and system efficiency.
RO Membrane Cleaner (Acidic / Low pH)
This low-pH cleaner is intended to clean away mineral scale, iron and manganese deposits, helping restore membrane flux after scaling, and ensuring long-term stability of the system.
Non-Oxidizing Biocide
This agent is a powerful tool to control bacteria, algae, and biofilms. It’s safe for RO membranes and is used periodically for biological control.
SMBS (Sodium Metabisulphite)
SMBS acts as a dechlorinator, removing residual chlorine and protecting membranes from oxidative damage during RO.
We also provide complete plant utilities with boiler water treatment chemicals for integrated water treatment solutions.
How to Choose the Right Antiscalant : Selection Guide
Selecting the right anti scaling chemical for RO plant can be based on the composition of feed water, conditions of operation, and design of the system. The selection of the right antiscalant chemical ensures the best performance and minimises the cost of repair over time.
Water Type / Problem | Recommended Product | Dosage (Approx.) | Aries Product Code |

Which antiscalant is used in RO plants?
For RO plants, antiscalants are frequently polycarboxylate-based or phosphonate-based. Antiscalants inhibit mineral accumulation on membranes and promote system efficiency. Aries Chemical supplies both types of antiscalants to match feed water quality and industrial RO system requirements. They are selected based on scaling potential, water chemistry, and system design.
What is the cost of antiscalant chemical for RO plant?
Antiscalant chemical costs around 70 to 150 per kg, depending on the product type, application, and volume. The rate will vary based on the water quality and the size of the system. For a quote, you will need to contact Aries Chemical. Bulk orders and long-term contracts can also influence pricing significantly.
What is the formula for RO antiscalant?
RO antiscalants are proprietary blends with no formula. They typically contain polymers like polyacrylates, phosphonates, and sulfonated compounds. These ingredients work together to prevent scaling and improve membrane performance under different water conditions. The exact composition varies by manufacturer to suit specific water treatment challenges.
Which chemical is used in RO plants?
RO plants rely on a combination of chemicals, including antiscalants, non-oxidising biocides, SMBS dechlorination, and membrane cleaners. These chemicals ensure that the system is properly functioning, reduce fouling, and extend membrane life. Aries Chemical supplies a full range of these solutions. Each chemical plays a specific role in maintaining overall system efficiency and longevity.
What is the difference between antiscalant and membrane cleaner?
Antiscalants are chemical preventive products that can be used for preventing scale formation on membranes. Membrane cleaners are corrective substances used for clearing up existing fouling, scaling, or biological deposits in CIP systems to restore efficiency. Both are essential for maintaining optimal RO plant performance at different stages of operation.
