RO Pre-Treatment Chemicals Manufacturer & Bulk Supplier in India | Water Treatment Chemicals
RO Pre-Treatment Chemicals for Industrial Reverse Osmosis Plants
Micro Polymer Industries is a trusted RO Pre-Treatment Chemicals Manufacturer & Bulk Supplier in India, offering a wide range of water treatment chemicals for protecting RO membranes and improving the performance of industrial reverse osmosis systems.
RO pre-treatment is an important part of an RO plant because feed water can contain suspended solids, hardness, silica, iron, manganese, chlorine, organic matter, microorganisms and other contaminants that may affect membrane performance.
We manufacture and supply RO antiscalants, coagulants, flocculants, polyelectrolytes, activated carbon treatment chemicals, dechlorination chemicals, membrane cleaners and other water treatment chemicals used in different RO pre-treatment and membrane protection applications.
With 30+ years of experience, Micro Polymer Industries serves industrial RO plants, water treatment companies, EPC contractors, dealers, distributors and bulk chemical buyers across India.

What is RO Pre-Treatment?
RO pre-treatment is the process of conditioning feed water before it enters the reverse osmosis membrane system.
The main objective is to reduce or control contaminants that can cause:
- Membrane scaling
- Membrane fouling
- Biofouling
- Chlorine damage
- Colloidal deposition
- Increased differential pressure
- Reduced permeate flow
- Frequent membrane cleaning
- Reduced membrane life
The exact RO pre-treatment process depends on the quality of incoming water and the required RO operating conditions.
RO Pre-Treatment Chemicals We Manufacture & Supply
Micro Polymer Industries offers a range of chemicals for different RO pre-treatment requirements.
1. RO Antiscalant
RO antiscalants are used to control scale-forming compounds before and within the RO membrane system.
Depending on the formulation and water chemistry, antiscalants may help control deposits associated with:
- Calcium carbonate
- Calcium sulfate
- Barium sulfate
- Strontium sulfate
- Silica
- Other inorganic scale-forming compounds
Our RO antiscalant chemicals are available for industrial RO applications and bulk requirements.
2. Coagulants for RO Pre-Treatment
Coagulation can be used to destabilize suspended and colloidal particles before filtration.
We supply industrial coagulants including:
- PAC Powder
- PAC Liquid
- Polyamine
- Aluminium Sulphate
- Non-Ferric Aluminium Sulphate
- Customized coagulant formulations
Coagulant selection depends on the feed-water characteristics and the overall pretreatment system.
3. Polyelectrolyte / Flocculant
Polyelectrolytes are used in selected pre-treatment systems to improve aggregation and separation of suspended particles.
We supply:
- Anionic Polyelectrolyte
- Cationic Polyelectrolyte
- Nonionic Polyelectrolyte
- Dewatering Polyelectrolyte
- Customized polymer grades
These products can be evaluated for applications involving clarification, filtration and solid-liquid separation.
4. Dechlorination Chemicals
Free chlorine and other oxidizing agents can be harmful to many RO membrane types.
Where chlorine removal is required, dechlorination treatment may be incorporated before the RO membrane.
Micro Polymer Industries supplies Sodium Metabisulphite (SMBS) for applications where chemical dechlorination is required.
The required dosage should be determined according to the incoming chlorine concentration and treatment conditions.
5. RO Membrane Cleaning Chemicals
Even with effective pre-treatment, membranes may eventually require cleaning.
We supply RO membrane cleaning chemicals for CIP applications involving different types of deposits and fouling.
Depending on the fouling type, cleaning programs may involve suitable acidic or alkaline chemistry.
Cleaning conditions should follow the membrane manufacturer's recommendations.
RO Pre-Treatment Process

RO Membrane
The actual configuration can vary depending on feed-water quality, plant capacity and membrane requirements.
Not every RO plant requires every chemical or treatment stage.
Why RO Pre-Treatment Chemicals Are Important
The RO membrane is the core component of a reverse osmosis system, but membrane performance depends heavily on the quality of water entering the membrane.
Poor pre-treatment can result in:
Scaling
Hardness and other dissolved salts can form deposits on membrane surfaces.
Fouling
Suspended solids, colloids and organic matter can accumulate on membranes.
Biofouling
Microbiological growth can affect membrane performance.
Oxidation
Residual chlorine or other oxidants can damage membranes that are not chlorine-resistant.
Higher Operating Cost
Poor feed-water conditioning may result in increased cleaning frequency, higher pressure requirements and reduced membrane life.
A properly designed RO pre-treatment system helps control these risks.
Industrial RO Pre-Treatment Chemicals
Micro Polymer Industries supplies industrial RO pre-treatment chemicals for a wide range of water treatment applications.
Our products can be considered for:
- Borewell water
- Surface water
- Municipal water
- Industrial process water

Chemical selection should always be based on actual water quality and the RO system design.
RO Pre-Treatment Chemical Selection
The correct chemical should be selected according to the actual feed-water characteristics rather than simply choosing a generic RO chemical.
Important parameters include:
- TDS
- pH
- Total hardness
- Calcium hardness
- Alkalinity
- Sulphate
- Silica
- Iron
- Manganese
- Chloride
- Free chlorine
- Turbidity
- SDI
- Temperature
- RO recovery
- Membrane type
For antiscalant selection, a detailed water analysis is strongly recommended.
