Reverse Osmosis Plant (RO)

At The Sigma Watertech Corporation, we design and manufacture high-performance Reverse Osmosis (RO) Systems engineered for superior water purification across industrial, commercial, and domestic applications. Our RO systems are built with precision to deliver high-quality, safe, and pure water, meeting stringent standards for diverse usage requirements.

About The Sigma Watertech Corporation

What is a Reverse Osmosis (RO) System?

A Reverse Osmosis (RO) system is an advanced multi-stage water purification technology that removes up to 95–99% of dissolved impurities from water. The process works by applying pressure to the feed water, forcing it through a semi-permeable membrane that separates pure water molecules from contaminants such as salts, heavy metals, chemicals, pesticides, and microorganisms.

The result is crystal-clear, odor-free, and great-tasting purified water, ideal for drinking, industrial processes, and specialized applications where water quality is critical.

  • Compact, modular, and easy-to-maintain system design
  • Available in manual, semi-automatic, and fully automatic configurations
  • Corrosion-resistant construction ensuring long service life
  • Optional pre- and post-treatment units for customized water quality
  • Compliance with BIS, WHO, and industrial water quality standards
Applications of Reverse Osmosis Systems

Our RO systems are designed for a wide range of applications, including:

  • Drinking Water Purification (Residential & Institutional)
  • Industrial Process Water for manufacturing and utilities
  • Pharmaceutical and Laboratory Use
  • Food & Beverage Production
  • Hotels, Hospitals, and Commercial Establishments
  • Brackish and Seawater Desalination
Types of RO Systems Offered
  • Domestic RO Systems – Compact and efficient systems for residential use.
  • Commercial RO Systems – Medium-capacity units for offices, hotels, and hospitals.
  • Industrial RO Systems – High-capacity systems designed for continuous operation in manufacturing and process industries.
  • Containerized RO Plants – Mobile, prefabricated units ideal for remote or temporary installations.

RO Process Overview

  • Pre-Treatment The feed water passes through sediment filters to remove suspended solids like dirt, rust, and silt, followed by activated carbon filters that eliminate chlorine, organic impurities, odors, and taste compounds. This protects the RO membrane from fouling and extends its lifespan.
  • High-Pressure Pumping The pre-treated water is pressurized (typically 8–14 bar for freshwater/brackish sources and 40–70 bar for seawater) using a high-pressure pump to overcome natural osmotic pressure and push water through the RO membrane.
  • Membrane Filtration (Core Stage) The heart of the system is the semi-permeable RO membrane, which allows only pure water molecules to pass while rejecting salts, organics, fluoride, nitrates, heavy metals, and microbes into a separate concentrate stream.
  • Post-Treatment & Polishing The purified (permeate) water then undergoes post-carbon filtration for improved taste and may include optional stages like remineralization (adding calcium & magnesium) or UV/Ozone disinfection to enhance purity and safety.
  • Waste Management & Efficiency

    RO produces two streams:

    • Permeate: Treated, purified water.
    • Concentrate: Rejected wastewater containing impurities.

    Domestic RO units typically reject 1.9 liters of wastewater per liter of purified water, while industrial multi-stage systems can achieve higher recovery efficiencies (~70–80%).
