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.

Core Process

The ROL-11780 operates on proven reverse osmosis technology, following a three-step workflow optimized for reliability:

  1. 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.

  2. 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.

  3. 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.

Water Treatment Applications

The ROL-11780 supports critical water treatment needs across sectors, including:

  • Industrial: Boiler feedwater purification, cooling tower water reuse, and EDI pretreatment for power plants 🔶1-15🔶1-54.

  • Food & Beverage: Bottled water production and beverage blending, ensuring product safety 🔶1-15🔶1-48.

  • Pharmaceutical & Electronics: High-purity water for drug formulation and semiconductor manufacturing 🔶1-15🔶1-49.

  • Municipal: Safe drinking water supply and wastewater recycling to meet sustainability goals 🔶1-15🔶1-53.

Competitive Advantages

  1. Large-Volume Output: 550,000 GPD capacity caters to high-demand facilities, reducing reliance on multiple smaller systems.

  2. Durable & Adaptable: FRP membrane housings resist corrosion, while TDS upgradability and optional add-ons (e.g., UV sterilization, remote monitoring) fit diverse needs 🔶1-24🔶1-21🔶1-39.

  3. Cost-Efficient: Automated control minimizes manual intervention, and low-maintenance components lower long-term operational costs.

  4. Reliable Purity: Consistent removal of contaminants ensures output meets industry-specific standards for safety and performance 🔶1-7🔶1-15.

For water treatment facilities seeking a scalable, high-performance solution, the ROL-11780 leverages Fenigal’s expertise to deliver reliable, large-scale purification, making it a top choice for industrial and commercial demands.
