Reverse Osmosis (RO) System Manufacturer & Supplier 


A Reverse Osmosis (RO) system is a water purification technology that uses a semi-permeable membrane to remove ions, molecules, and larger particles from drinking water. It works by applying pressure to the contaminated side of the membrane to overcome osmotic pressure, forcing purified water through while leaving most dissolved salts and impurities behind. As a leading RO System Manufacturer & Supplier In Chennai, we specialize in delivering high-performance, customized solutions that meet the diverse needs of our clients—from compact domestic units to large-scale industrial systems.

What are reverse osmosis systems?

A Reverse Osmosis (RO) system is an advanced water purification technology that removes dissolved salts, impurities, and contaminants from water by forcing it through a semi-permeable membrane. The process works by applying pressure to water, allowing only pure water molecules to pass while blocking impurities such as bacteria, heavy metals, chemicals, and dissolved solids. RO systems are widely used for producing clean and safe drinking water in homes, offices, and industries. They improve taste, odor, and quality of water, making it suitable for human consumption, food processing, pharmaceuticals, and other applications requiring high-purity water.

How Does Reverse Osmosis Work?

Reverse Osmosis (RO) is a highly effective water purification process that works by forcing water through a semi permeable membrane to remove dissolved salts, minerals, chemicals, and impurities. When pressure is applied to the water, the membrane acts as a selective barrier, allowing only pure water molecules to pass through while rejecting contaminants like heavy metals, bacteria, chlorine, and other dissolved solids. The rejected impurities are flushed out as waste, while the purified water is collected for use. This process not only improves water taste and odor but also ensures safe, clean water for drinking, cooking, and industrial applications. Unlike conventional filtration, RO works at a molecular level, delivering high-quality water that meets health and safety standards. Widely used in households, industries, and commercial facilities, reverse osmosis is recognized as one of the most reliable, efficient, and sustainable methods for producing pure water.

Reverse Osmosis - The Basics

Reverse Osmosis is one of the most effective water purification technologies available today. It works by forcing water through a semi-permeable membrane, removing:

  • Dissolved salts and minerals
  • Heavy metals like lead and arsenic
  • Microorganisms and bacteria
  • Chemical contaminants
  • Odors and taste impurities

The result? Clean, safe, and great-tasting water—ideal for drinking, cooking, manufacturing, and more.

Types of Reverse Osmosis (RO) System

  • Point-of-Use (POU) RO Systems: Compact units typically installed under a kitchen sink for drinking water.
  • Point-of-Entry (POE) RO Systems: Larger systems for whole-house or commercial use.
  • Commercial/Industrial RO Systems: High-capacity units for various industrial applications (e.g., manufacturing, power generation, pharmaceuticals).
  • Brackish Water RO (BWRO): Designed for water with moderate salinity.
  • Seawater RO (SWRO) / Desalination Plants: Large-scale systems for converting seawater into fresh water.

Applications in Various Industries

  • Applications: Drinking water purification (residential, commercial), bottled water production, industrial process water (e.g., semiconductor manufacturing, boiler feed water, pharmaceuticals, food and beverage processing), wastewater treatment, agriculture, dialysis centers, desalination.
  • Semi-Permeable Membrane: The core component, typically made of Thin Film Composite (TFC) material, often polyamide, chosen for high rejection rates and flow.
  • Pre-filtration: Sediment filters (to remove large particles), activated carbon filters (to remove chlorine, odors, chemicals) are crucial to protect the RO membrane.
  • Booster Pump: Often used to increase water pressure for efficient membrane operation, especially for low inlet pressure or high recovery rates.
  • Post-filtration: Carbon filters for taste and odor improvement, demineralization filters to add beneficial minerals back to purified water.
  • High-Pressure Pumps: Essential for commercial and industrial systems, especially SWRO.
  • Energy Recovery Devices: In large SWRO plants, devices like pressure exchangers or turbochargers recover energy from the concentrated brine stream, significantly reducing energy consumption.
  • Automated Controls & Monitoring: PLC (Programmable Logic Controller) systems for automatic operation, backwashing, membrane flushing, and performance monitoring.

Material Selection Considerations

  • RO Membrane: Primarily Thin Film Composite (TFC) membranes, often polyamide, chosen for their selective permeability, durability, and resistance to degradation from various water chemistries (though chlorine is detrimental).
  • Membrane Housings/Pressure Vessels: Fiberglass Reinforced Plastic (FRP) for industrial systems due to high pressure resistance and corrosion resistance; PVC or polypropylene for smaller residential units.
  • Piping: UPVC (Unplasticized Polyvinyl Chloride), CPVC (Chlorinated Polyvinyl Chloride), polypropylene, or stainless steel (304, 316) for chemical resistance, pressure rating, and preventing contamination.
  • Pumps: Stainless steel, cast iron, or specialized alloys resistant to corrosion, especially for high-salinity water.
  • Filter Housings: Polypropylene, ABS, or other durable plastics for pre- and post-filters.
  • Fittings and Valves: PVC, polypropylene, or stainless steel.
  • Frame: Powder-coated steel or stainless steel for structural support and corrosion resistance.

FAQ's

Where can I install a reverse osmosis system?
RO systems can be installed under kitchen sinks, in commercial spaces, or at industrial plants depending on size and capacity needs.

What impurities does reverse osmosis remove?
RO systems remove dissolved salts, heavy metals, chlorine, fluoride, nitrates, bacteria, viruses, and other harmful substances.

What is reverse osmosis and its advantages?

Advantages of Reverse Osmosis:


  • Removes up to 99% of contaminants – Including salts, bacteria, and heavy metals.

  • Improves taste and odor – Produces clean, fresh-tasting water.

  • Low energy consumption – Especially in modern systems.

How does reverse osmosis work?
Reverse osmosis (RO) works by using a high-pressure pump to force water through a semi-permeable membrane. This membrane allows only pure water molecules to pass while blocking dissolved salts, minerals, bacteria, and other impurities. The result is clean, purified water on one side (permeate) and concentrated waste on the other (reject or brine).

What are reverse osmosis systems?
Reverse Osmosis (RO) Systems are advanced water purification systems that use a semi-permeable membrane to remove impurities, dissolved salts, heavy metals, bacteria, and other contaminants from water. The process forces water through the membrane under pressure, allowing only clean water (permeate) to pass through while flushing away contaminants (reject or brine water).
