RO MEMBRANE

🔬 What it removes:

RO membranes typically filter out:

• Dissolved salts (TDS reduction)
• Lead, arsenic, fluoride
• Nitrates and sulfates
• Heavy metals
• Many bacteria and viruses (very high rejection rate)

⚙️ How it works:

Water is pushed through the membrane at pressure:

• Clean water molecules pass through
• Contaminants are rejected and flushed away as waste

📏 Common specs:

• Pore size: ~0.0001 micron
• Flow rate: typically 50–100 GPD (gallons per day) for residential units
• Operating pressure: ~40–100 PSI depending on model
• Rejection rate: often 95–99% of dissolved solids

🏠 Where it’s used:

• Under-sink drinking water systems
• Whole-home water treatment (less common, larger systems)
• Commercial and industrial water purification
