ROL-18780 Top-Tier RO System for Ultra-Large-Scale Water Treatment
The ROL-18780 is the high-capacity flagship industrial reverse osmosis (RO) system from Wuxi Fenigal Science & Technology Co., Ltd. (Fenigal FG Water Technologies), engineered to meet the most demanding ultra-large-scale water purification needs in the water treatment industry. As the top model in the ROL series—renowned for its 200,000~900,000 GPD capacity range—it integrates high-efficiency 8” TFC spiral-wound membranes and heavy-duty components to remove most contaminants from tap or well water, producing low-dissolved-solids output that adheres to strict purity standards for industrial, commercial, and municipal applications 🔶2-3🔶2-14🔶2-20.
The ROL-18780 operates on proven reverse osmosis technology, following a three-step workflow optimized for reliability and high performance:
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 that impairs membrane efficiency 🔶2-26🔶2-75.
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 via the system’s spiral membrane configuration 🔶2-22🔶2-67🔶2-71🔶2-77.
Smart Monitoring: A PLC-based control panel with an HMI screen tracks key metrics (permeate conductivity, flow rates, pressure) and uses programmable set points, enabling automated operation and consistent water purity 🔶2-28🔶2-30🔶2-32.

Municipal: Large municipal drinking water supply and wastewater recycling projects 🔶2-15🔶2-53.
Maximum Capacity: 900,000 GPD output meets ultra-large-scale demands, eliminating the need for multiple smaller systems and reducing installation complexity 🔶2-82.
Heavy-Duty Durability: FRP membrane housings resist corrosion, and TEFC motors withstand harsh industrial environments, ensuring long service life 🔶2-22🔶2-24.
Flexible Adaptability: TDS upgradability to 5,000 ppm and optional add-ons (UV sterilization, remote monitoring, chemical dosing) fit diverse feedwater conditions 🔶2-21🔶2-35🔶2-39🔶2-71.
Cost-Effective Automation: PLC-based controls minimize manual intervention, while low-maintenance components lower long-term operational costs 🔶2-28🔶2-30.
For water treatment facilities requiring the highest capacity and reliability, the ROL-18780 leverages Fenigal’s expertise to deliver unmatched large-scale purification, making it the industry’s top choice for ultra-demanding applications.
