Reverse Osmosis (RO) Water Purification Process

Reverse Osmosis (RO) is a modern water purification process that ensures clean and safe drinking water by removing impurities, bacteria, and harmful particles. This process uses a special semi-permeable membrane to filter out contaminants, leaving only pure water behind.

How Does Reverse Osmosis Work?

• Applied Pressure: Pressure is applied to counteract natural osmotic pressure, allowing water to pass through the membrane.
• Selective Filtration: The membrane blocks large molecules and ions while letting smaller water molecules (H₂O) flow through.
• Wide Applications: RO is ideal for drinking water purification and industrial processes.

How is Reverse Osmosis Different from Filtration?

Reverse Osmosis works differently compared to traditional filtration systems:

• Filtration: Uses size exclusion with pores of 0.01 micrometers or larger to trap impurities.
• RO Mechanism: Utilizes a nonporous or nanofiltration membrane with pores as small as 0.001 micrometers. It removes impurities based on solubility and diffusivity differences, influenced by pressure and concentration levels.

Performance Features of RO Membranes

• Salt Rejection: 97%–98%
• Permeate Flow: 80 GPD (Gallons Per Day)
• Diameter: 2 inches
• Length: 12 inches

Testing Conditions for Optimal Performance

• Pressure: 60 PSI
• Temperature: 25°C
• pH Range: 6.0–7.5
• Salt Concentration: 500 ppm
• Recovery Rate: 15%

Why Choose Reverse Osmosis for Water Purification?

Reverse Osmosis is a reliable and efficient method for ensuring clean water free from harmful impurities. Whether for household use or industrial applications, RO systems are a top choice for maintaining water quality and health.
