0.5T/H Laboratory RO System | Double Purification Technology

Intro: Need laboratory-grade pure water? Our 0.5T/H (500L/H) two-stage reverse osmosis system delivers exceptional water quality with double purification. Perfect for pharmaceutical, electronics, and critical industrial applications where standard RO isn't enough.

What is Two-Stage Reverse Osmosis Technology?

Reverse Osmosis (RO) is advanced membrane separation technology developed in the 1960s. It works by applying high pressure to force water through a semi-permeable membrane, separating pure water from dissolved salts and contaminants.

How Two-Stage RO Works:

 • First Stage: Removes 97-99% of dissolved solids and contaminants

 • Second Stage: Polishes the already purified water from first stage

 • Final Result: Achieves significantly higher purity than single-stage systems

This double-barrier approach ensures ultra-pure water for your most demanding applications.

Critical Feed Water Requirements

For optimal performance, your feed water must meet these specifications:

 • SDI (Silt Density Index): < 4.0

 • Conductivity: < 400 μS/cm

 • Dissolved Oxygen: < 1.5 mg/L

 • Chloride Ions: < 0.5 mg/L

 • Iron Content: < 0.05 mg/L

Pro Tip: Pre-treatment is essential to meet these inlet requirements and protect your RO investment.
