ROL-6680 Reverse Osmosis System

Comprehensive Overview of ROL-6680 Reverse Osmosis System

The ROL-6680 is an advanced commercial-grade reverse osmosis system belonging to the renowned ROL Series developed by Wuxi Fenigal Science & Technology Co., Ltd. Designed to deliver exceptional water purification performance, this system is tailored to convert tap water or well water into low-solids purified water through a state-of-the-art reverse osmosis process. At its core lies a set of high-performance reverse osmosis membranes, which work by applying pressure to force water through a semi-permeable barrier, effectively removing up to 99% of dissolved salts, organic contaminants, heavy metals, and other impurities. The versatility of the ROL-6680 reverse osmosis system makes it ideal for a diverse array of applications, such as high-purity water production for electronic component manufacturing, boiler water treatment to minimize scaling and enhance energy efficiency, pharmaceutical-grade water preparation that adheres to strict regulatory standards, municipal water desalination projects, industrial wastewater recycling, food and beverage processing where water quality directly impacts product safety, and cosmetic production requiring ultra-clean water sources.

When it comes to standard configurations, the ROL-6680 reverse osmosis system is equipped with 8” high-rejection TFC spiral wound membranes, a choice that ensures long-term reliability and consistent contaminant removal efficiency. These membranes are installed in corrosion-resistant FRP (Fiberglass Reinforced Plastic) membrane housings, which provide robust protection against external damage and maintain stable operating conditions. The system is powered by a heavy-duty stainless steel multi-stage centrifugal pump with a TEFC (Totally Enclosed Fan Cooled) motor, offering superior durability and energy efficiency while delivering the necessary pressure for the reverse osmosis process. A 5-micron sediment pre-filter is integrated at the inlet to capture large particles, silt, and debris, preventing membrane fouling and extending the service life of the core components. For user-friendly operation and real-time monitoring, the system features a PLC (Programmable Logic Controller) based control panel with an intuitive HMI (Human-Machine Interface) touchscreen, allowing operators to set parameters, track performance data, and receive alerts for maintenance or abnormal conditions. Additional safety and monitoring devices include low-pressure and high-pressure switches, precision liquid-filled pressure gauges, a permeate conductivity monitor for real-time purity testing, and dedicated flow meters for both permeate and concentrate streams, ensuring full visibility of the system’s operational status.

To achieve optimal performance, the ROL-6680 reverse osmosis system has specific operational requirements. The maximum feed water temperature it can efficiently handle is 45°C, with a recommended feed water TDS (Total Dissolved Solids) range of 0-3,000 ppm; for applications with higher TDS levels (up to 6,000 ppm), the system can be upgraded with specialized membranes and enhanced pretreatment. Hydrogen sulfide in the feed water must be removed to prevent membrane degradation, and the maximum silica tolerance is 30 ppm at a 65% recovery rate. The feed water pressure should be maintained between 25 to 85 psi, while the operating pressure for the reverse osmosis process ranges from 180 to 280 psi. The feed water pH tolerance spans 2-12, and the maximum allowable iron content is 0.05 ppm; any turbidity exceeding 1 NTU must be treated prior to entering the system. If the feed water hardness exceeds 1.5 GPG, an optional water softener is recommended to prevent scale formation on the membranes, which can significantly reduce performance over time.

A wide range of optional features are available to customize the ROL-6680 reverse osmosis system according to specific application needs. These include remote monitoring systems that enable off-site access to operational data via mobile or desktop platforms, feed water conductivity and pH monitors with digital sensors for comprehensive water quality analysis, automated membrane cleaning skids that simplify maintenance and restore membrane performance, product tank level switches for automatic control of water storage, chemical dosing systems for antiscalants, biocides, or pH adjusters, multimedia prefiltration systems for enhanced removal of organic matter and colloids, UV sterilization or ozonation units for microbial disinfection of permeate water, skid-mounted configurations with integrated pretreatment or post-treatment modules for easy installation, and containerized solutions for mobile or temporary water treatment projects. These options make the ROL-6680 a highly flexible reverse osmosis system capable of adapting to diverse industrial and commercial environments.

The ROL-6680 reverse osmosis system adopts the advanced membrane module assembly characteristic of the ROL Series. Each membrane module consists of multiple spiral-wound membrane elements arranged in a series-parallel configuration within FRP pressure vessels. During operation, feed water enters the pressure vessels and flows across the membrane surfaces, while purified permeate water passes through the membrane layers and collects in the central perforated tube, exiting as product water. The concentrate stream, containing the rejected impurities, is discharged or recirculated based on system settings. The membrane module design, including the spacing between membrane elements and the flow distribution structure (as referenced in the document’s membrane assembly diagram), ensures uniform water flow and maximum membrane utilization, contributing to the system’s high efficiency and consistent performance.
