ROL-8680 Industrial Reverse Osmosis System

ROL-8680: A High-Efficiency Model of FENIGAL’s Industrial Reverse Osmosis System

The ROL-8680 stands as a flagship model in FENIGAL’s ROL Series Commercial Reverse Osmosis System, designed to address high-demand water purification scenarios across industrial and commercial sectors. As a premium offering in the reverse osmosis system portfolio, it leverages advanced reverse osmosis technology—forcing water through a high-performance semi-permeable membrane under precise pressure to eliminate over 99% of dissolved solids, heavy metals, bacteria, and other contaminants. This capability allows it to convert raw water (such as tap water, well water, or surface water) into high-purity water, making it ideal for applications like electronic component manufacturing, pharmaceutical formulation, power plant boiler feed water, beverage production, municipal wastewater recycling, and large-scale desalination projects.

In terms of structural design and core components, the ROL-8680 reverse osmosis system integrates cutting-edge features to guarantee consistent performance and durability. It is fitted with 8” high-rejection TFC spiral wound membranes, which are the heart of the reverse osmosis system’s contaminant removal process. The spiral membrane assembly of this reverse osmosis system consists of multiple membrane leaves wrapped around a central perforated tube; raw water flows along the membrane surface, while purified permeate passes through the membrane layers and converges into the central tube for collection, as shown in the "Spiral Membrane Configuration" diagram within the document (located in the ROL Series technical specifications section detailing membrane structures).

Other standard components of the ROL-8680 reverse osmosis system include a corrosion-resistant stainless steel multi-stage centrifugal pump with a TEFC (Totally Enclosed Fan Cooled) motor, ensuring stable pressure output and long-term operation; high-strength FRP (Fiberglass Reinforced Plastic) membrane housings that withstand high operating pressures and resist chemical corrosion; a 5-micron sediment pre-filter to trap large particles and prevent membrane clogging; an intelligent PLC control system with a touchscreen HMI, enabling automated operation, real-time parameter monitoring, and alarm notifications; integrated motor starters with overload protection; low/high-pressure safety switches to safeguard the system from pressure fluctuations; precision liquid-filled pressure gauges for accurate pressure tracking at key points; a permeate conductivity analyzer to continuously verify water purity; and high-precision flow meters for permeate and concentrate streams. Furthermore, the ROL-8680 reverse osmosis system offers flexible customization options, including remote monitoring systems (supporting IoT connectivity), feed water TDS and pH monitors, automatic membrane cleaning skids, product water tank level controllers, chemical dosing systems (for scale and corrosion inhibition), multimedia pre-filtration units, UV sterilization or ozonation modules, water softeners (for high-hardness feed water), skid-mounted integrated designs (for easy installation), and containerized solutions (for mobile or temporary water treatment needs).

Regarding operational parameters, the ROL-8680 reverse osmosis system adheres to strict industry standards to maintain optimal efficiency and membrane lifespan. The maximum allowable feed water temperature is 45°C, and the recommended feed water pressure ranges from 25 to 90 psi. The feed water TDS (Total Dissolved Solids) can be up to 3,000 ppm for standard configurations, with optional upgrades available to handle TDS levels up to 6,000 ppm by adjusting the system’s recovery rate. The feed water pH range is 2-12, and the maximum iron content must be kept below 0.03 ppm to prevent membrane fouling. Hydrogen sulfide and turbidity must be pre-removed from the feed water, and the system can tolerate up to 30 ppm of silica at a 65% recovery rate. The normal operating pressure of the reverse osmosis system is between 180 to 280 psi, optimized to balance purification efficiency and energy consumption.
