ROL-11780 High-Efficiency RO System for Large-Scale Water Treatment
The ROL-11780 is a high-capacity industrial reverse osmosis (RO) system developed by Wuxi Fenigal Science & Technology Co., Ltd. (Fenigal FG Water Technologies), tailored to meet large-volume water purification demands in the water treatment industry. As a key model in the ROL series—known for its 200,000~900,000 GPD capacity range—it integrates high-efficiency 8” TFC spiral-wound membranes and rugged components to remove most contaminants from tap or well water, producing low-dissolved-solids output that aligns with strict standards for diverse industrial and commercial applications 🔶1-13🔶1-20.
The ROL-11780 operates on proven reverse osmosis technology, following a three-step workflow optimized for reliability:
Pretreatment: A 5-micron cartridge prefilter eliminates sediments and turbidity to protect RO membranes; for feedwater with hardness over 1 GPG, optional water softeners are available to prevent scaling 🔶1-26🔶1-41.
Pressurized Filtration: A stainless steel multi-stage pump with a TEFC motor pushes feedwater (0-2,000 ppm TDS, upgradable to 5,000 ppm) through membranes at 150–250 psi. Contaminants are discharged as concentrate, while purified permeate spirals inward to a central collection tube 🔶1-22🔶1-71🔶1-77.
Smart Monitoring: A PLC-based control panel with an HMI screen tracks permeate conductivity, flow rates, and pressure, enabling automated operation and consistent water purity 🔶1-28🔶1-32.
