Equipment composition

 

The main components of the equipment are pretreatment unit module, reverse osmosis (RO) unit module, energy recovery device , post-treatment unit module and control system module, as follows:

1. Pretreatment unit: including multi-media filter, activated carbon filter, softener, security filter, etc., used to remove suspended matter, organic matter, hardness ions and other impurities in seawater.

2. Reverse Osmosis (RO) Unit: A high-pressure pump is used to provide sufficient pressure for the seawater, which is used to intercept the salt in the seawater through the reverse osmosis membrane and allow pure water to pass through.

3. Energy recovery device: such as turbine energy recovery device or pressure difference energy recovery device, used to recover part of the energy and reduce energy consumption.

4. Post-treatment unit: includes mineralization system and disinfection system, which are used to improve the taste and nutritional content of desalinated water and ensure the safety and sterility of desalinated water.

5. Control system: including automatic control system and water quality monitoring system, used to monitor and control the entire desalination process.

6. Storage and distribution system: It includes water storage tanks and pumping stations, which are used to store the treated desalinated water and transport it to the user's water supply network or directly for industrial use.

 

 

Application scenarios


Islands and coastal areas: Provide fresh water to islands and coastal areas to alleviate water shortages.

Arid areas: Provide fresh water to arid areas to support agricultural irrigation and residential water use.

Industrial water: Provide high-quality industrial water for industries such as chemicals, pharmaceuticals, and electricity.
Emergency water supply: Provide temporary fresh water supply in natural disasters or emergencies.

Technical principle of

 

The membrane method mainly uses a semi-permeable membrane to intercept the salt and other impurities in seawater and allow pure water to pass through, thereby achieving seawater desalination. The most commonly used technology is reverse osmosis (RO) . Under high pressure, seawater passes through the reverse osmosis membrane, which only allows water molecules to pass through, while most of the salt and impurities are intercepted. The details are as follows: 

Pretreatment: Remove suspended matter, organic matter and other impurities in seawater through multi-media filters, activated carbon filters, etc.

Reverse Osmosis: A high-pressure pump provides enough pressure for the seawater to pass through the reverse osmosis membrane, which traps the salt in the seawater and allows pure water to pass through.

Energy recovery: Recover part of the energy through the energy recovery device to reduce energy consumption.

Post-treatment: Improve the taste and nutritional content of desalinated water through the mineralization system, and ensure the safety and sterility of desalinated water through the disinfection system.

Storage and distribution: The treated desalinated water is stored and transported to the user's water supply network through pumping stations or directly used for industrial purposes.

Frequently Asked Questions

 

Questions

Countermeasures

Question 1: After long-term operation, the reverse osmosis membrane is easily contaminated by organic matter, inorganic salts, microorganisms, etc., resulting in a decrease in membrane flux and an increase in pressure difference.

Countermeasures : Carry out chemical and physical cleaning regularly, use appropriate scale inhibitors and bactericides, improve pretreatment process, and improve influent quality.

Question 2: During the reverse osmosis process, calcium, magnesium and other ions in seawater will form hard scale on the membrane surface, affecting membrane performance.

Countermeasures: Use appropriate scale inhibitors, adjust the pH value of the inlet water, optimize the pretreatment system, and clean the membrane components regularly .

Question 3: The operation of the seawater desalination system consumes a lot of energy, especially the high-pressure pump in the reverse osmosis process.

Countermeasures: Use energy-efficient high-pressure pumps, utilize energy recovery devices (such as turbine energy recovery devices), and optimize system design to reduce energy consumption.

Question 4: The reverse osmosis membrane may be damaged due to physical damage, chemical erosion or microbial growth, affecting the desalination effect.

Countermeasures: Check the status of the membrane regularly, ensure the effectiveness of the pretreatment system, and avoid using chemicals that are harmful to the membrane.

Question 5: Components such as filters and softeners in the pretreatment system may malfunction, resulting in a decrease in incoming water quality.

Countermeasures: Regularly inspect and maintain pretreatment equipment to ensure its normal operation.

Question 6: A malfunction in the automated control system may cause the system to fail to operate normally.

Countermeasures: Perform system maintenance and inspection regularly to ensure that the control system is stable and reliable.

Question 7:  The concentrated water produced during the reverse osmosis process contains a high concentration of salt and needs to be properly handled.

Countermeasures: Use appropriate concentrated water treatment technology, such as reinjection into the ground, evaporation pond treatment, etc.

Question 8: The desalination process may have an impact on the surrounding environment. For example, the discharged concentrated water may affect the marine ecosystem.

Countermeasures: Adopt environmentally friendly technologies, rationally plan emissions, and reduce the impact on the environment.

Question 9: Equipment is susceptible to corrosion in seawater and high-salinity environments.

Countermeasures: Use corrosion-resistant materials, perform anti-corrosion treatment regularly, and strengthen equipment maintenance.

Question 10: Operator errors may cause system failure or accidents.

Countermeasures: Strengthen employee training to ensure the correct implementation of operating procedures.

Question 11: The salinity, temperature, turbidity and other water quality parameters of seawater vary with the seasons, which may affect the desalination effect.

Countermeasures: Adjust pretreatment and desalination process parameters according to changes in water quality to ensure stable operation.

Question 12: The maintenance cost of the seawater desalination system is high, including equipment maintenance and consumables replacement.

Countermeasures: Choose durable equipment, optimize maintenance plans, and reduce unnecessary expenses.
