Product Description:

The seawater desalination reverse osmosis (RO) system is a high-efficiency membrane separation technology that removes dissolved salts and impurities from seawater to produce usable fresh water.

The system can achieve a desalination rate of up to 99% by applying advanced reverse osmosis membranes, and is equipped with an energy recovery device to significantly reduce energy consumption.

In addition, the pretreatment system can effectively remove suspended matter and pollutants in seawater to ensure the normal operation of the reverse osmosis membrane and extend its service life.

Influent pretreatment: Seawater first passes through the pretreatment unit to remove large particulate matter, algae and other suspended matter to protect the reverse osmosis membrane and improve its performance.

High-pressure pump pressurization: The pretreated seawater is pressurized by a high-pressure pump to the pressure required by the reverse osmosis membrane, usually between 40 and 70 bars.

Membrane separation process: Under high pressure conditions, water molecules pass through the reverse osmosis membrane, while salt and other pollutants are retained. Pure water flows out to form fresh water; concentrated water is discharged or further processed.

Energy recovery: The energy recovery device installed in the system uses the pressure of the concentrated water to recover part of the energy and reduce overall energy consumption.

Outlet monitoring: The final fresh water is tested by the water quality monitoring system to ensure that the outlet water quality meets the drinking water standard or industrial water standard.

Product Function:

• High-efficiency desalination: Provides up to 99% salt removal rate to ensure that the outlet water quality meets industry standards.
• Real-time water quality monitoring: Real-time detection of outlet water quality through monitoring equipment to ensure safe and stable water use.
• Intelligent control system: Realize automated operation and remote monitoring to improve operating efficiency.
• Energy-saving design: The energy recovery system reduces operating costs and improves economic benefits.

Features:

Optimized Membrane Structure

The optimized membrane structure guarantees that the fresh water generated meets rigid water quality standards and caters to diverse water needs. The system's membrane design ensures that the water purification process is effective and removes impurities, providing high-quality water. The optimized membrane structure ensures that the water is fit for consumption.

Skid Design

The skid design of the water purification system makes it highly adaptable and easily maintainable. The novel framework can accommodate the desalination requirements of various scales with its modular approach. The desalination needs of small, medium, and large-scale operations can be easily met through the skid design of the system.

Low Maintenance Frequency

The system has been designed to ensure that it maintains high durability, thus reducing its maintenance cost. System design optimization and high-quality materials ensure that the system can withstand harsh environments and require infrequent maintenance. The result is a low-frequency maintenance schedule, which ensures that the system functions effectively and has minimal downtime.

Environmentally Friendly

The water purification system was designed to be eco-friendly. By effectively using seawater resources, it helps alleviate water scarcity problems, and promote sustainable development. The system reduces the need for water from alternative sources and thus reduces the footprint left by conventional water treatment methods. The system's holistic approach to water purification ensures that it is an efficient, sustainable solution for water purification.

Applications:

Urban water supply is essential to ensure that residents in water-scarce cities have access to a stable supply of fresh water. The provision of fresh water to cities is crucial for the proper functioning and wellbeing of its residents. It is essential to ensure that the water supply is reliable and that residents have access to sufficient quantities of clean water.

Agricultural irrigation is necessary to support agricultural production in arid areas. Reliable irrigation water sources are vital in areas where there is little or no rain. Without access to stable sources of water, farmers would be unable to grow crops, and food production would decline.

The development of coastal tourism requires fresh water sources to support the development of service industries, such as hotels and restaurants. Coastal tourist areas, especially those in tropical regions, require an uninterrupted supply of fresh water to meet the needs of their visitors. Without access to a reliable water supply, these areas would be unable to support the tourism industry.

In emergency situations like natural disasters or droughts, people stranded in these areas require rapid deployment of drinking water. Emergency rescue teams can ensure that disaster-stricken people have access to clean drinking water, which is essential to their survival. Clean water is vital in emergency situations, and it is essential to provide it promptly.

The industrial sector requires a lot of water and utilizes it in various processes. The chemical, electric power, and food processing industries all require significant quantities of water for their operations. Therefore, having stable sources of water is essential to ensure the smooth running of these industries and their contribution to the economy.
