ROL-16780 High-Capacity RO System for Large-Scale Water Treatment

Category: Containerized Seawater Reverse Osmsosis (SWRO) System

The ROL-16780 is a heavy-duty industrial reverse osmosis (RO) system developed by Wuxi Fenigal Science & Technology Co., Ltd. (Fenigal FG Water Technologies), designed to tackle high-volume water purification demands in the water treatment industry. As a flagship model in the ROL series—with a capacity range of 200,000~900,000 GPD—it adopts 8” TFC spiral-wound membranes and robust components to remove most contaminants from tap or well water, producing low-dissolved-solids output that meets strict standards for diverse industrial, commercial, and municipal applications 🔶2-3🔶2-14🔶2-20.

Core Process

The ROL-16780 operates on proven reverse osmosis technology, following a three-step workflow optimized for efficiency:

Pretreatment: A 5-micron cartridge prefilter eliminates sediments and turbidity to protect RO membranes; feedwater with hardness over 1 GPG can be paired with optional water softeners to prevent scaling 🔶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 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 purity 🔶2-28🔶2-30🔶2-32.
