Detailed Specifications of ROL-5680 Reverse Osmosis System

The ROL-5680 is a high-performance model under the ROL Series Commercial Reverse Osmosis System developed by Wuxi Fenigal Science & Technology Co., Ltd. It is specifically engineered to produce low dissolved solids water from tap or well water, leveraging high-efficiency reverse osmosis membranes— a core component that enables the reverse osmosis process, which removes a large majority of contaminants by pushing water under pressure through a semi-permeable membrane. This reverse osmosis system is well-suited for a wide range of critical applications, including semiconductor manufacturing (where ultra-pure water is essential for preventing component damage), boiler feed (to reduce scaling and improve boiler efficiency), pharmaceutical production (ensuring water meets strict purity standards for drug formulation), municipal water treatment, water reuse projects, food processing (maintaining product quality and safety), and beverage bottling (guaranteeing clean and pure drinking water), among others.

In terms of standard features, the ROL-5680 reverse osmosis system is equipped with 8” TFC spiral wound membranes, which are key to its efficient contaminant removal. These membranes are housed in durable FRP membrane housings that protect the membranes and ensure stable operation. The system also includes a stainless steel multi-stage pump with a TEFC motor, providing reliable power to push water through the membrane at the required pressure. A 5 micron cartridge prefilter is integrated to remove larger particles from the feed water, preventing clogging of the reverse osmosis membranes and extending their lifespan. For easy operation and monitoring, the system features a PLC based control panel with programmable time delay and set points, along with an HMI screen that allows operators to access real-time system data. Additionally, it is equipped with essential safety and monitoring components such as a low pressure switch, high pressure switch, liquid filled pressure gauges, permeate conductivity monitor (to track the purity of the produced water), and permeate & concentrate flow meters (to monitor water flow rates). A motor starter is also included to ensure safe and smooth startup of the system’s motor.

For operation, the ROL-5680 reverse osmosis system has specific requirements and parameters to ensure optimal performance. The maximum feed water temperature it can handle is 42°C, and the feed water TDS (Total Dissolved Solids) should be between 0-2,000 ppm; if the TDS exceeds this range, the system can be upgraded to handle up to 5,000 ppm, though operating at higher TDS may require lowering the recovery rate. Hydrogen Sulfide must be removed from the feed water, and the maximum silica tolerance is 25 ppm at 60% recovery. The feed water pressure should be between 20 to 80 psi, while the operating pressure ranges from 150 to 250 psi. The pH tolerance range of the feed water is 3-11, and the maximum iron content allowed is 0.05 ppm; any turbidity in the feed water should also be removed. If the feed water hardness exceeds 1 GPG, a water softener (available as an option) is necessary to prevent scaling on the membranes.

Optional features are available to customize the ROL-5680 reverse osmosis system based on specific application needs. These include remote monitoring (allowing for off-site tracking of system performance), feed water conductivity monitor (for more detailed feed water quality analysis), membrane cleaning skid (to facilitate regular membrane maintenance and extend membrane life), product tank level switch (to control the level of produced water in the storage tank), feed pH monitor with sensor and feed ORP monitor with sensor (for comprehensive feed water chemistry monitoring), water and hour meters (to track water usage and system runtime), chemical dosing systems (for adding chemicals such as antiscalants or biocides), media prefiltration systems (for additional pre-treatment of feed water), ozonation and UV sterilization systems (to disinfect the produced water), water softeners (for hardness removal), skid mounted with pre or post treatment (for easy installation and integration with existing water treatment setups), and containerized RO systems (providing a compact and mobile solution for on-site water treatment).

The ROL-5680 reverse osmosis system utilizes the spiral membrane configuration typical of the ROL Series. The spiral membrane is constructed from one or more membrane envelopes wound around a perforated central tube. During operation, the permeate (purified water) passes through the membrane into the envelope and spirals inward to the central tube for collection. The layers of the membrane envelope, including components like the fabric backing, plasticized tricot sealant, and spacer (as referenced in the document’s membrane diagram), work together to ensure efficient water purification and flow.
