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

Working Principle:

The seawater desalination reverse osmosis system follows a simple working principle:

• 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:

The seawater desalination reverse osmosis system offers the following benefits:

• High-efficiency desalination: Provides up to 99% salt removal rate to ensure that the outlet water quality meets industry standards.

Features:

An optimized membrane structure is in place to guarantee that the fresh water produced meets strict water quality standards. Additionally, it is tailored to fulfill various water needs, making sure that the end product is always of the highest quality and meets the necessary standards.

The structure of the water desalination system adopts a skid design that simplifies its expansion and maintenance. It can easily adapt to the desalination needs of different scales, making it a versatile solution for a range of applications.

The maintenance frequency of the system is low thanks to the design optimization and high durability. This characteristic significantly reduces the system's maintenance cost which can lead to long-term cost savings when compared to other desalination systems.

The water desalination system is environmentally friendly. It effectively utilizes seawater resources, alleviates water shortage problems, and promotes sustainable development. By using this system, the environment is preserved, and natural resources are preserved for the benefit and enjoyment of future generations.

Technical Parameters:

Our water treatment system is capable of handling water usage ranging from 5 to 1000 m³/h, depending on the scale of the equipment. The system is designed to handle brine concentration of seawater TDS30,000 to 40,000 mg/L, and boasts a desalination rate of over 98%. It is suitable for use in seawater temperature range of 5 to 40℃, while its recovery rate ranges from 30% to 50%, with the potential to go up to 70% or higher.

The system operates at between 40 to 80 bar (580~1160 psi), with the capacity to go up to 100 bar or more. A single membrane element on the system has a membrane area of between 1 to 5 m², with the ability to combine multiple elements to form a membrane area as large a necessary.

For optimum performance, the system's temperature should range between 20~30°C. Prior to usage, suspended solids concentration must be less than 1 mg/L. The system requires cleaning every time or between every 6 months to 1 year. The effluent water quality is set at TDS≤600mg/L, and meets the "World Health Organization (WHO) Drinking Water Quality Standards", or individualized requirements for higher indicators as specified by clients.

Applications:

Ensuring access to fresh water is crucial for the well-being of citizens living in water-scarce cities. A stable supply of fresh water needs to be provided to meet the daily needs of households and businesses. This can be accomplished through the installation of water treatment plants, water storage facilities, and effective distribution networks to ensure that water is delivered to where it is needed most.

Arid areas often struggle with water scarcity, which can have a significant impact on agricultural production. Reliable irrigation water sources are needed to ensure that crops can grow in these areas. This requires the implementation of irrigation systems that are designed to deliver water efficiently to crops in need. Investing in such systems is critical for the survival of agriculture in these harsh environments.

Fresh water is essential for the development of the tourism industry in coastal areas. Areas such as hotels and restaurants rely heavily on a steady supply of clean water to meet the needs of guests. It is essential to build infrastructure that can address the needs of the tourism industry, including water treatment facilities and distribution networks to ensure that water is delivered reliably and sustainably.

In times of natural disaster or drought, rapid deployment of drinking water is critical for the survival of disaster-stricken communities. Water is a basic human need, and without access to it, people are at risk of facing severe health issues. Therefore, it is necessary to have emergency plans in place to provide drinking water quickly and efficiently during times of crisis.

Water is also essential for the needs of industries such as chemical, electric power, and food processing. These sectors often require huge amounts of water, and so it is necessary to establish infrastructure that can support these water needs. This can be achieved through the installation of water treatment facilities and water reuse systems, which will help to minimize water waste and promote sustainability in these industries.
