Reverse Osmosis (RO)

Advanced Water Purification Technology for High-Quality Water

Reverse osmosis (RO) is one of the most effective water purification technologies available today. It uses a semi-permeable membrane to remove dissolved salts, heavy metals, bacteria, and impurities from water.

RO systems are widely used in residential, commercial, and industrial applications where high-purity water is required.

What Is Reverse Osmosis?

Reverse osmosis is a membrane separation process that removes up to 99% of dissolved solids (TDS) by applying pressure to force water through a semi-permeable membrane.

The membrane allows water molecules to pass while blocking:

  • Dissolved salts

  • Heavy metals

  • Fluoride

  • Nitrates

  • Chlorine

  • Organic contaminants

  • Bacteria and viruses

The result is clean, purified water with significantly reduced TDS levels.

How Reverse Osmosis Works

The typical RO process includes:

1️⃣ Pre-treatment (sediment + carbon filtration)
2️⃣ High-pressure pump
3️⃣ RO membrane separation
4️⃣ Post-treatment (optional mineralization or polishing)

Proper pretreatment is essential to protect the membrane and extend system lifespan.

Types of Reverse Osmosis Systems

1️⃣ Residential RO Systems

Under-sink or countertop systems for drinking water purification.

2️⃣ Whole House RO Systems

Centralized purification for the entire home.

3️⃣ Commercial RO Systems

Designed for offices, schools, restaurants, and small businesses.

4️⃣ Industrial RO Systems

Large-scale systems for manufacturing, pharmaceutical, food processing, and boiler feed water.

Applications of Reverse Osmosis

  • Drinking water purification

  • High TDS water treatment
