Items of Activated Carbon in Water Treatment Process

Activated carbon has a wide range of applications in water treatment, including household water purifiers, sewage treatment plants, industrial water treatment, etc. Specific applications include adsorbing harmful substances such as organic matter, odor, pigments, heavy metal ions, adjusting the pH value of water, and removing bacteria and viruses.

Mechanism of Activated Carbon in Water Treatment:

1. Adsorption of organic compounds: The microporous structure of activated carbon provides a large surface area to adsorb organic compounds in water, such as pesticides, solvents and volatile organic compounds.

2. Removes chlorine and chloramines: Activated carbon effectively removes chlorine and chloramines from drinking water. These compounds are commonly used for disinfection but can affect the taste and odor of the water.

3. Removes odors and odors: Activated carbon can significantly improve the taste and smell of water by adsorbing the substances that are the source of odors.

4. Removing heavy metals: Certain types of activated carbon can be used to absorb heavy metals such as lead and mercury after special treatment.

Precautions for use in Water Treatment Process:

1. Regular replacement: The activated carbon filter element will be saturated after being used for a period of time, and its adsorption capacity will decrease. It needs to be replaced regularly according to usage to ensure the filtration effect.

2. Initial flushing: The newly installed activated carbon filter element needs to be fully flushed before first use to remove possible carbon powder or impurities.

3. Combination filtration: In some cases, activated carbon filtration is combined with other types of filtration, such as reverse osmosis or UV disinfection, to provide more comprehensive water quality assurance.

Through the above applications and precautions, it can be seen that activated carbon plays an important role in the water filtration process and is of great significance to improving water quality and protecting health.
