Reverse osmosis (RO) is a pressure-driven membrane process that removes dissolved salts, organic compounds, and microorganisms to produce high-purity water.

How RO Works

Applied pressure overcomes the osmotic pressure of the solution. Semi-permeable membranes allow water molecules to pass while rejecting dissolved solids (98%+ rejection typical).

Applications

• Seawater and brackish water desalination
• Industrial process water
• Boiler feed water
• Electronics manufacturing
• Pharmaceutical and medical water
• Food and beverage production
• Wastewater recovery

System Components

Pre-Treatment

Multi-media filtration, softeners, anti-scalant dosing, and cartridge filtration protect membranes.

RO Membranes

Composite polyamide thin-film composite membranes in spiral-wound configuration. Various sizes and capacities.

High-Pressure Pump

Stainless steel pump provides pressure for membrane separation (typically 200-400 psi for brackish, 800-1000 psi for seawater).

Post-Treatment

pH adjustment, mineral dosing, and UV sterilization for product water quality.

Performance Parameters

• Salt rejection: 95-99.5%
• Recovery rate: 50-85%
• Operating pressure: 200-1000 psi
• Membrane life: 3-5 years with proper pre-treatment
