ROL-14780 Industrial-Grade RO System for High-Demand Water Treatment
The ROL-14780 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-scale, high-demand 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 integrates 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, commercial, and municipal applications 🔶2-3🔶2-14🔶2-20.
The ROL-14780 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 🔶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.

High-Volume Output: 697,368 GPD capacity caters to ultra-high-demand facilities, reducing reliance on multiple smaller systems 🔶2-82.
Durable Design: FRP membrane housings resist corrosion, and the TEFC motor withstands harsh industrial environments, extending service life 🔶2-22🔶2-24.
Flexibility: Supports TDS upgrades to 5,000 ppm and optional add-ons (UV sterilization, remote monitoring, chemical dosing) to fit diverse needs 🔶2-21🔶2-35🔶2-39🔶2-71.
Cost Efficiency: Automated controls minimize manual intervention, while low-maintenance components lower long-term operational costs 🔶2-28🔶2-30.
For water treatment facilities seeking a scalable, high-performance solution, the ROL-14780 leverages Fenigal’s expertise to deliver consistent, large-scale purification—making it a top choice for industrial and municipal demands.
