Automatic Flushing 400 GPD RO System
Commercial 5-Stage Stand type RO System 400GPD Per Day ( With Pumps ) (Automatic Flushing Membrane) ( With automatic flush controller which can flush RO-film regularly) The purpose of the flush system is to help prevent scaling or fouling of the RO membrane(s) by providing a rapid rinse which washes away impurities and keeps the membrane clean.The auto flush system noticeably increases the service life of the membranes in reverse osmosis systems.
Functions:
- Indicate TDS.
- Flush the RO System.
- Turn Off RO on low Pressure.
- Turn Off RO on High Pressure.
- Control RO High Pressure Pump.
Description
The UltraTec Automatic Flushing 400 GPD RO System is a compact commercial reverse osmosis water purification system designed to produce high-quality drinking water for offices, restaurants, cafés, laboratories, clinics, schools, and other commercial applications. Built as a complete stand-type RO system with integrated pumps, the unit combines advanced 5-stage filtration with an automatic membrane flushing controller to improve purification efficiency and extend membrane life. The automatic flushing function helps reduce membrane scaling and fouling by periodically rinsing accumulated impurities from the RO membrane. This improves overall system performance, reduces maintenance requirements, and increases the operational life of the membrane while delivering a reliable supply of purified water.
What This System Does?
The Automatic Flushing 400 GPD RO System is designed for commercial applications that require a continuous supply of purified drinking water with improved membrane protection and automated operation. It is suitable for offices, restaurants, cafés, schools, clinics, laboratories, staff accommodations, retail outlets, hotels, and other commercial facilities using municipal or borewell water. The system helps reduce dissolved salts, chlorine, sediment, unwanted taste, odour, and other impurities through multi-stage reverse osmosis filtration. Its automatic flushing controller regularly cleans the RO membrane, helping reduce fouling and scaling while maintaining stable water quality and extending membrane service life.
How It Works
Water first passes through sediment and activated carbon pre-filters, which help reduce suspended particles, chlorine, and organic contaminants before reaching the RO membrane. The reverse osmosis membrane then removes dissolved salts, minerals, and other impurities to produce purified water.The built-in automatic flushing controller periodically flushes the membrane with clean water to remove accumulated contaminants. The controller also displays TDS values, monitors system pressure, protects the RO unit from low-pressure and high-pressure conditions, and automatically controls the high-pressure pump for reliable operation.
