Activated Carbon Technology in Water Treatment

What is activated carbon technology?

Activated carbon technology is an effective water filtration method that uses activated carbon as an adsorbent to remove residues, organics, chemicals and other contaminants in water. Activated carbon is a type of coal that is specially treated to create small holes in its structure, increasing its ability to adsorb impurities that exist in water.

Working principle of activated carbon technology

As water flows through the activated carbon layer, contaminants such as heavy metal ions, organic compounds, and water-soluble organic matter are adsorbed to the surface of the activated carbon. This process occurs due to chemical interactions between the contaminants and the active substances on the surface of the activated carbon, such as ion adsorption or the formation of chemical bonds with organic molecules.
The small pore structure and large surface area of activated carbon create a favorable environment for the process, as it enhances the contact ability between water and the activated carbon surface. Activated carbon, on the other hand, can be produced with different physical and chemical properties to increase the adsorption performance of specific pollutants.

What is the activated carbon technology system?

Activated carbon technology system consists of the following components:
  • Tank: This is where the filtered water is poured in and goes through the filtration process.
  • Filter column: The filter column is where the activated carbon is stored. Activated carbon is usually arranged as layers or particles in the filter column.
  • Pump system: The pump system is used to push water through the filter column and through the activated carbon.
  • Control system: The control system is used to control the filtration process, including the adjustment of water pressure and flow.

Reviews of activated carbon technology:

Advantages of activated carbon technology:
  • High filtration efficiency: Activated carbon technology is able to effectively remove contaminants in water such as heavy metal ions, organic compounds and water-soluble organic matter.
  • High strength: Activated carbon has the ability to be reused many times after removing contaminants, which extends the life of the filtration system.
  • Easy to use: Activated carbon technology does not require complicated processes and is easy to operate.
Limitations of activated carbon technology:
  • Replacing and recycling: Activated carbon needs to be replaced periodically after it has absorbed a certain amount of pollutants to maintain filtration efficiency. Moreover, the activated carbon recycling process also requires special measures to treat the pollutants that have been adsorbed in the coal.
  • Cost: Activated carbon technology has relatively high initial and operating costs, especially when periodic replacement of activated carbon is required.

Important applications of activated carbon technology

Activated carbon technology has many important applications in the field of water purification, including:
  • Drinking water filtration: Activated carbon technology is widely used in drinking water filtration systems to remove contaminants and improve water quality.
  • Wastewater treatment: Activated carbon technology can be applied to wastewater treatment, which removes organic matter, chemicals and other contaminants before the water is discharged into the environment.
  • Industrial: Activated carbon technology is also used in industrial processes such as chemical manufacturing, food processing, and industrial waste gas treatment to remove pollutants.

Some projects use typical activated carbon technology

  1. Activated carbon water purification project in West Basin, Los Angeles, USA: This project uses a recycled water filtration system to convert wastewater into reusable water. The filtration process involves using activated carbon to remove contaminants in wastewater and producing safe reusable water for irrigation purposes and other industries.
  2. Activated carbon water purification project at the Water Trust, South Africa: This project focuses on water purification to provide clean drinking water to rural communities. Activated carbon-based water purification systems are deployed to remove contaminants, bacteria and micro-sizing in the water.
  3. Activated carbon water purification project in Hanoi: In some areas in Hanoi, activated carbon water filtration systems have been deployed to provide clean drinking water. This technology helps remove pollutants, bacteria and dirt in water sources, ensuring safe drinking water for people.

Faq about activated carbon technology?

Is it necessary to periodically replace activated carbon during water purification with activated carbon technology? Yes, activated carbon needs to be replaced periodically after it has absorbed a certain amount of contaminants to maintain filtration efficiency.
Is it possible to recycle activated carbon after it has adsorbed the pollutants? Yes, activated carbon can be recycled after it has absorbed the pollutants. However, the activated carbon recycling process requires special measures to treat and remove the pollutants that have adsorbed in the coal. This recycling process may include methods such as pyrolysis, oxidation, or chemical treatment to degrade the pollutants and restore the adsorption capacity of activated carbon. The recycling process may also create new activated carbon additives for use in other applications.
Is activated carbon technology effective for the removal of contaminants in water? Activated carbon technology is considered an effective method for the removal of contaminants in water. With its small pore structure and large surface area of activated carbon, it is able to effectively adsorb pollutants such as heavy metal ions, organic compounds and water-soluble organic matter. The filtration process by activated carbon technology can remove up to 99% of various contaminants, which improves water quality and protects human health.

Conclusion on activated carbon technology:

Activated carbon technology is an effective and popular water purification method in removing pollutants and improving water quality. With the principle of operation based on the adsorption process by activated carbon, this technology is capable of removing heavy metal ions, organic compounds and water-soluble organic matter.
Although there are limitations such as the need to replace and recycle activated carbon periodically and at high cost, activated carbon technology is still widely used in the field of drinking water purification, wastewater treatment and industrial.Projects using activated carbon technology that Natural Star Vina deployed from construction, design and operation achieve high efficiency, maximum cost savings for businesses.
