High-Performance RO Antiscalants for Industrial, Commercial & Desalination Applications


OCH Chemicals & Systems is an RO antiscalant manufacturer in India, specializing in high-performance water treatment chemicals for Reverse Osmosis (RO) and Nanofiltration (NF) membrane systems.

Based in Chennai, Tamil Nadu, OCH Chemicals & Systems supplies RO antiscalants for different feed-water conditions, including low-TDS water, high silica, high hardness, iron-containing water and high-TDS/desalination applications.

Our RO antiscalant range is developed to help control scale formation, reduce membrane fouling, maintain RO system performance and support longer membrane operating life.

OCH serves industrial RO plants, commercial RO systems, packaged drinking water plants, mineral water plants, pharmaceutical industries, food and beverage industries, textile industries, power plants, chemical industries and water-treatment companies across India.


Why RO Antiscalant Is Important in Reverse Osmosis


Reverse Osmosis membranes are vulnerable to the deposition of dissolved minerals and suspended contaminants.

As water passes through an RO membrane, water recovery increases the concentration of scale-forming substances in the reject stream. Depending on the feed-water chemistry and RO operating conditions, calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, silica and metal-related deposits can become potential scaling or fouling problems.

An appropriately selected RO antiscalant helps maintain scale-forming substances in a controlled state and reduces the tendency for deposits to form on the membrane surface.

The correct antiscalant selection should consider:

  • Feed-water TDS

  • Calcium hardness

  • Alkalinity

  • Silica concentration

  • Sulfate concentration

  • Barium and strontium

  • Iron and manganese

  • Fluoride

  • Feed-water pH

  • RO recovery

  • Operating temperature

  • Membrane type

  • Number of membrane stages

  • Concentration factor

  • Required dosage

OCH Chemicals & Systems provides application-oriented RO antiscalant solutions based on feed-water conditions and RO operating parameters.

For severe biological contamination, an appropriate RO biocide and membrane-cleaning program should also be considered rather than relying on antiscalant alone.


How to Select the Right RO Antiscalant

There is no single RO antiscalant that is automatically suitable for every water source.

The correct product depends on the chemistry of the feed water and the RO operating conditions.

Step 1 – Test the feed water

Important parameters include:

  • pH

  • TDS

  • Conductivity

  • Calcium hardness

  • Magnesium

  • Total alkalinity

  • Silica

  • Sulfate

  • Chloride

  • Iron

  • Manganese

  • Fluoride

  • Temperature

Step 2 – Check RO operating conditions

The following information should also be evaluated:

  • Feed flow

  • Permeate flow

  • Reject flow

  • Recovery percentage

  • Operating pressure

  • Membrane model

  • Number of elements

  • Number of stages

  • Array configuration

Step 3 – Calculate concentration at the membrane

The concentration of dissolved minerals increases as water recovery increases.

Therefore, antiscalant selection should not be based only on the feed-water TDS.

Step 4 – Select the appropriate OCH grade

Based on water chemistry and operating conditions, an appropriate OCH antiscalant can be selected.

Step 5 – Establish the dosage

The final chemical dosage should be determined according to feed-water chemistry, recovery, temperature, membrane configuration and antiscalant performance.


RO Antiscalant Dosing

RO antiscalant dosing is normally carried out using a chemical dosing pump.

The actual dosage should be determined based on:

Feed flow × required chemical concentration

For example, if an RO system requires a calculated chemical concentration of 3 ppm, the dosing pump capacity and chemical dilution should be selected accordingly.

OCH Chemicals & Systems can provide technical support for RO antiscalant product selection, dosage estimation and dosing-pump setup based on plant operating data.

For technical recommendation, provide:

  1. RO feed flow

  2. Permeate flow

  3. Reject flow

  4. Recovery %

  5. Feed TDS

  6. Hardness

  7. Alkalinity

  8. Silica

  9. Sulfate

  10. pH

  11. Iron

  12. Temperature

  13. RO membrane model
