Activated Carbon for Seawater

Date :2025-03-18
Classify: Activated Carbon
Desalination is the production of fresh water by desalination of seawater. It is an open-source incremental technology for realizing the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. The water quality is good and the price is becoming more reasonable. It can ensure a stable water supply for drinking water for coastal residents and water replenishment for industrial boilers. In the process of desalination, activated carbon has become one of the key materials for desalination due to its excellent adsorption performance.

Removing Odors and Color from Seawater: 

Seawater often contains substances that produce unpleasant odors, such as sulfides from decomposed organic matter. Activated carbon effectively absorbs these odor-causing compounds, leaving the purified seawater odor-free. Additionally, algae and microorganisms in seawater can release pigments that affect its appearance. Activated carbon can also remove these pigments, restoring the water’s clear and transparent state. This property is utilized in seawater desalination pretreatment processes, providing cleaner water for subsequent steps.

Reducing Microorganisms in Seawater:

While seawater naturally contains numerous microorganisms, certain applications—like aquaculture and marine biology experiments—require controlling their levels. The microporous structure of activated carbon not only traps impurities but also provides a surface for microorganisms to adhere to. As seawater passes through the activated carbon filter, some microorganisms are captured, reducing their overall presence. However, it’s important to note that activated carbon does not kill microorganisms but helps lower their numbers through physical filtration.

Supporting Seawater Desalination:

Activated carbon plays a key role in seawater desalination. Before desalination, impurities must be removed to protect equipment and prolong its lifespan. Activated carbon removes residual chlorine, which can damage critical components like reverse osmosis membranes. It also effectively absorbs colloids and suspended particles, improving seawater quality and ensuring a more efficient and stable desalination process.

The real applicaitons area 

Seawater desalination pretreatment

In the desalination process (such as reverse osmosis and distillation), pretreatment is a crucial step. Activated carbon is often used as one of the pretreatment materials to remove suspended particles, organic pollutants and residual chlorine in seawater. This not only improves the operating efficiency of subsequent desalination equipment, but also extends the service life of the equipment.

Water purification in marine aquaculture

Marine aquaculture farms need to maintain the cleanliness and stability of the water body to ensure the healthy growth of aquaculture organisms. Activated carbon can be used to remove harmful substances in aquaculture water, such as ammonia nitrogen, organic waste and drug residues, thereby improving the water quality environment.

Responding to marine pollution incidents

In marine oil spills or chemical pollution incidents, activated carbon is often used as an emergency treatment material. Its strong adsorption performance can quickly adsorb oil, chemicals and other pollutants in the water body, reducing the damage of pollution to the ecological environment.

Conclusion

Activated carbon is an essential material for seawater purification, known for its ability to efficiently remove odors, colors, organic pollutants, and microorganisms. It plays a critical role in improving water quality, protecting desalination systems, and ensuring the success of various applications such as seawater desalination, aquaculture, and environmental cleanup.
