ROL-7680 Industrial Reverse Osmosis System

ROL-7680: A High-Capacity Model of FENIGAL’s Industrial Reverse Osmosis System

The ROL-7680 is a key model in FENIGAL’s ROL Series Commercial Reverse Osmosis System, engineered to deliver efficient water purification for diverse industrial and commercial needs. As a vital part of the reverse osmosis system lineup, it adheres to the core principle of reverse osmosis technology—removing a large majority of contaminants from water by pushing water under pressure through a semi-permeable membrane. This enables it to produce low dissolved solids water from tap or well water, making it suitable for a wide range of applications such as semiconductor manufacturing, boiler feed water supply, pharmaceutical production, municipal water treatment, water reuse projects, food processing, and bottling operations, among others.

In terms of design and components, the ROL-7680 reverse osmosis system incorporates a set of standard features that ensure its reliability and performance. It is equipped with 8” TFC spiral wound membranes, which are essential for effective contaminant removal. The spiral membrane of this reverse osmosis system is constructed from one or more membrane envelopes wound around a perforated central tube; the permeate passes through the membrane into the envelope and spirals inward to the central tube for collection, as illustrated in the "Spiral Membrane Configuration" diagram within the document (located in the section detailing the spiral membrane structure of the ROL Series Commercial Reverse Osmosis System).

Other standard features of the ROL-7680 reverse osmosis system include a stainless steel multi-stage pump with a TEFC motor, ensuring stable water pressure and efficient operation; FRP membrane housings that provide durable protection for the membranes; a 5-micron cartridge prefilter to remove larger particles and prevent membrane fouling; a PLC-based control panel with an HMI screen for easy operation and monitoring, along with programmable time delays and set points to adapt to different working conditions; motor starters for safe and reliable pump activation; low and high-pressure switches to protect the system from pressure anomalies; liquid-filled pressure gauges for accurate pressure monitoring; a permeate conductivity monitor to ensure the quality of the produced water; and permeate & concentrate flow meters to track water flow rates. Additionally, like other models in the series, the ROL-7680 can be equipped with various available options to meet specific application requirements, such as remote monitoring for real-time system status tracking, a feed water conductivity monitor for input water quality assessment, a membrane cleaning skid for regular membrane maintenance, a product tank level switch for automated water storage control, feed pH and ORP monitors with sensors for water chemistry monitoring, water and hour meters for usage tracking, chemical dosing systems for water treatment enhancement, media prefiltration systems for further particle removal, ozonation and UV sterilization systems for disinfection, water softeners (especially useful when feed water hardness exceeds 1 GPG), skid-mounted designs with pre or post-treatment, and containerized RO systems for easy transportation and installation.

When it comes to operation specifications, the ROL-7680 reverse osmosis system complies with the series-wide standards to ensure optimal performance and longevity. The maximum feed water temperature it can handle is 42°C, and the feed water pressure ranges from 20 to 80 psi. The feed water TDS (Total Dissolved Solids) should be between 0-2,000 ppm, though the system can be upgraded to handle TDS up to 5,000 ppm if needed; it can also operate at higher TDS levels by lowering the recovery rate. The pH tolerance range of the feed water is 3-11, and the maximum iron content in the feed water must not exceed 0.05 ppm. Hydrogen sulfide must be removed from the feed water, turbidity should be eliminated, and the maximum silica tolerance is 25 ppm at a 60% recovery rate. The operating pressure of the system is between 150 to 250 psi, ensuring effective membrane filtration.
