Product Overview
The FG-RO-500L is a compact, skid-mounted reverse osmosis purification system engineered for small commercial and light industrial water treatment applications. Delivering a steady permeate flow of 500 liters per hour (3,200 GPD), this integrated unit combines pretreatment, high-pressure RO separation, and online monitoring within a single 304 stainless steel frame. It is designed to convert tap, well, or municipal water into high-purity drinking water with consistent reliability and minimal operational complexity.
Key Features
500 L/H Stable Output:Delivers a continuous permeate capacity of 500 liters per hour, suitable for small commercial treatment needs including beverage preparation, food processing wash water, and potable water supply for facilities without centralized treatment infrastructure.
Integrated RO Filtration Process:Employs spiral-wound composite membrane technology to remove dissolved salts, organic matter, submicron colloidal particles, color, nitrate, and bacteria from feed water. The system achieves a salt rejection rate of 99.5% under standard testing conditions.
SS304 Stainless Steel Skid Frame:The entire membrane housing, piping layout, and structural frame are constructed in 304 stainless steel, providing corrosion resistance, structural stability, and long service life under continuous industrial operation.
Complete Monitoring & Control Panel:Equipped with a digital controller, three pressure gauges for real-time pressure differential monitoring, and three panel-mounted flow meters for permeate and concentrate flow verification. This instrumentation enables operators to confirm membrane performance and system integrity at a glance.
Compact Integrated Skid Design:Membrane elements, high-pressure pump, pretreatment cartridges, and all interconnecting piping are pre-assembled on a single skid. This plug-and-play configuration reduces on-site installation time and minimizes footprint requirements.
Verified Quality Documentation:Each unit is supported by a video outgoing inspection and a machinery test report prior to shipment, providing buyers with documented evidence of assembly quality and operational readiness.
