Reverse Osmosis (RO) Plant

The Heart of a Modern Water Purification System

Transforming Raw Water into Pure, Safe, and High-Quality Drinking Water.

A Reverse Osmosis (RO) Plant is an advanced water purification system that uses a semi-permeable membrane and high pressure to remove dissolved salts, bacteria, viruses, heavy metals, chemicals, and other impurities from water.
RO technology is one of the most effective and widely used purification methods in the packaged drinking water, mineral water, pharmaceutical, and food industries.

What is Reverse Osmosis?

The word “Osmosis” means the natural movement of water from a low-concentration solution to a high-concentration solution through a semi-permeable membrane.

Reverse Osmosis works in the opposite direction. By applying pressure, pure water is forced through the membrane while impurities are rejected and removed as wastewater.

How Does an RO Plant Work?

Step 1: Raw Water Collection

Water is collected from:

✅  Borewell
✅  River
✅  Municipal Supply
✅  Surface Water Sources

Step 2: Pre-Treatment System

Multi-Grade Sand Filter

Removes:
✅ Dust
✅ Sand
✅ Suspended particles
✅ Turbidity

Activated Carbon Filter

Removes:
✅  Chlorine
✅  Bad odor and taste
✅  Organic impurities

Water Softener

Removes:
✅  Calcium
✅  Magnesium
✅  Hardness-causing minerals

Step 3: Micron Cartridge Filter

Removes fine particles up to 5 micron or 1 micron and protects the RO membranes.

Step 4: High-Pressure Pump
The high-pressure pump increases water pressure to force water through the RO membrane.
Step 5: RO Membrane

The membrane removes:

✅ Dissolved Salts (TDS)
✅ Bacteria and Viruses
✅ Heavy Metals
✅ Fluoride
✅ Arsenic
✅ Iron
✅ Chemical Contaminants
