ROL-18780 Top-Tier RO System for Ultra-Large-Scale Water Treatment

Category: Containerized Seawater Reverse Osmsosis (SWRO) System

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.

Core Process

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.
