Two-Stage RO Water Systems: 2025 Technical Guide
Why Choose Two-Stage RO?
✔ 98% Salt Rejection - Produces ultra-pure water
✔ Energy Efficient - 30% lower power than distillation
✔ Compact Design - 50% smaller footprint than mixed bed systems
✔ Chemical-Free - No acid/alkali regeneration required
Industry Standard: Achieves <5μS/cm conductivity (vs <10μS/cm for single-stage)
