ROL-11680 Industrial-Grade RO System for Large-Scale Water Treatment
The ROL-11680 is a high-capacity industrial reverse osmosis (RO) system developed by Wuxi Fenigal Science & Technology Co., Ltd. (Fenigal FG Water Technologies), designed to address large-scale water purification needs in the water treatment industry. As a key model in the ROL series—known for its 200,000~900,000 GPD capacity range—it adopts high-efficiency RO membranes and rugged components to remove most contaminants from tap or well water, producing low-dissolved-solids output that meets strict standards for diverse industrial and commercial applications 🔶1-131.
The ROL-11680 operates on proven reverse osmosis technology, following a three-step workflow optimized for reliability:
Pretreatment: A 5-micron cartridge prefilter removes sediments and turbidity to protect RO membranes, while optional water softeners handle feedwater with hardness over 1 GPG to prevent scaling 🔶1-262.
Pressurized Filtration: A stainless steel multi-stage pump with a TEFC motor pushes feedwater (0-2,000 ppm TDS) through 8” TFC spiral-wound membranes at 150–250 psi; contaminants are discharged as concentrate, while purified permeate is collected via a central tube 🔶1-20🔶1-2211.
Smart Monitoring: A PLC-based control panel with an HMI screen tracks permeate conductivity, flow rates, and pressure, enabling automated operation and consistent purity 🔶1-283.
