2025Best-Selling Compact Reverse Osmosis System | 0.25T/H, 250L/H Pure Water Production
This reverse osmosis (RO) system is an advanced water purification unit designed to efficiently produce high-quality drinking water through semi-permeable membrane filtration. By utilizing pressure differentials, the system effectively removes up to 99.5% of dissolved salts, heavy metals, bacteria, organic impurities, colloids, and other harmful substances—including asbestos, radium, and various chemicals that affect taste, odor, and color.
Key Features:
Continuous and fully automated operation ensures a consistent supply of purified water.
Chemical-free regeneration process for easy and eco-friendly maintenance.
Equipped with a high-performance CNP pump and Vontron reverse osmosis membrane for reliable filtration.
Intelligent pure water and raw water tank control: automatic refill at low level and shut-off at high level.
Integrated 90-second automatic membrane flushing function to reduce scaling and prolong membrane life.
Built-in water pump protection with low-pressure and dry-run safety switches.
Real-time water quality monitoring with an online conductivity meter and digital display.
Comprehensive instrumentation includes flow meters, pressure gauges, solenoid valves, control valves, and a user-friendly control panel.
Fully automated operation via a dedicated RO controller for minimal manual intervention.
Simple to operate and maintain, making it ideal for small-scale and point-of-use applications.
