Two-stage reverse osmosis equipment, also known as reverse osmosis units, is a water treatment device that removes ions and impurities from water through a two-stage reverse osmosis process. It is widely used in purified water production, the electronics and pharmaceutical industries, and seawater desalination.
This equipment utilizes a "raw water → pretreatment unit → primary RO system → secondary RO system → water storage" process. It features two RO membrane modules: a primary RO system (50% recovery rate) and a secondary RO system (80% recovery rate). It treats qualified municipal tap water (conductivity ≤ 300 μs/cm), producing water with a conductivity of ≤ 2 μs/cm.
Equipment Advantages:
High-Efficiency Desalination: Effectively removes dissolved salts from water, typically achieving a desalination rate of double 97%, significantly reducing salinity and meeting the water quality requirements of many industrial and domestic applications.
Extensive Impurity Removal: In addition to salt, it removes a wide range of impurities, including organic matter, colloids, bacteria, and viruses. The resulting effluent is of high quality, suitable for producing high-quality industrial and drinking water.
Stable Operation: The equipment boasts a high degree of automation. Once the operating parameters are set, it operates continuously and stably, minimizing manual intervention. The monitoring and control system provides real-time monitoring of key parameters such as water quality, pressure, and flow rate to ensure stable operation.
Easy Operation: Relatively simple to operate, trained personnel can master the equipment's operating procedures. Daily operations primarily include starting and stopping the equipment, monitoring parameters, and performing regular maintenance.
High Adaptability: The equipment can be designed and adjusted to suit varying raw water quality and product water requirements. It can accommodate a variety of water sources, including surface water and groundwater. By adjusting the pretreatment process and reverse osmosis system parameters, the system can meet the needs of diverse users.
