Fully automatic two-stage reverse osmosis precision filtration system for reducing salinity in water filtration

Product description

working principle:
Primary reverse osmosis: Raw water passes through a semi permeable membrane under the action of a high-pressure pump. The semi permeable membrane only allows water molecules to pass through, while impurities such as salt, bacteria, viruses, and organic matter in the water are intercepted. In the first stage reverse osmosis process, most of the salt and impurities are removed, and the salt content of the produced water is significantly reduced.
Secondary reverse osmosis: The water produced by the primary reverse osmosis is used as the inlet for the secondary reverse osmosis and then filtered through a semi permeable membrane. Secondary reverse osmosis further removes a small amount of residual salt and other impurities from the water, resulting in lower salt content and purer water quality. Through two-stage reverse osmosis precision filtration, the salinity of water can be effectively reduced, meeting the demand for high-purity water.
System composition:
Preprocessing unit: usually includes multi-media filters, activated carbon filters, softeners, etc. Multi media filters remove suspended solids, colloids, and other impurities from water; Activated carbon filters adsorb residual chlorine, organic matter, and odors in water; Softener reduces the hardness of water and prevents fouling of reverse osmosis membranes.
High pressure pump: provides sufficient pressure for the reverse osmosis membrane to allow water to pass through the semi permeable membrane. The performance of high-pressure pumps directly affects the water production and desalination rate of reverse osmosis systems.
Reverse osmosis membrane element: It is the core component of the system, generally using roll or hollow fiber reverse osmosis membranes. These membranes have the characteristics of high desalination rate and high water flux, which can effectively remove salt and other impurities from water.
Control system: Adopting PLC programmable controller and human-machine interface to achieve automated operation of the system. The control system can monitor the pressure, flow rate, water quality and other parameters of the system in real time, and automatically adjust the operating status of the system according to the set program, such as automatic flushing of the reverse osmosis membrane, automatic dosing, etc.
Post processing unit: including ultraviolet sterilizer, ozone generator, precision filter, etc., to further remove bacteria, viruses, and small particles from water, ensuring the hygiene and safety of the produced water.
characteristic:
High desalination rate: The desalination rate of two-stage reverse osmosis systems can usually reach over 98%, which can effectively reduce the salt content in water and produce high-purity water.
High degree of automation: Fully automated operation, no need for frequent manual operation, reducing labor intensity and operating costs. The system can automatically adjust its operating status based on water quality and operating parameters to ensure stable operation of the system.
Stable water quality: able to continuously and stably produce water quality that meets the requirements, meeting the strict requirements of different industries for water quality, such as electronics, pharmaceuticals, chemical industry, etc.
Low operating costs: By optimizing system design and adopting efficient reverse osmosis membrane components, the energy consumption and consumables consumption of the system have been reduced, thereby lowering operating costs.
Small footprint: The system has a compact structure and occupies a small area, which can save installation space.
This fully automatic two-stage reverse osmosis precision filtration system is widely used in fields such as seawater desalination, brackish water desalination, industrial pure water preparation, etc. It can effectively reduce the salt content in water and provide high-quality water sources.
