Activated Carbon for Water Purification is a porous carbon material with highly developed pore structures. Its porous nature provides a large surface area, allowing for extensive contact with gases (impurities), thereby endowing the activated carbon with unique adsorption properties. This makes it highly efficient in the collection of impurities. What are the classifications of water purification activated carbon?

What are the classifications of activated carbon for water purification?

1. Activated carbon is a crucial and widely used adsorbent material in water purification systems, with other adsorbents including neutral macroporous resins, macroporous anion resins, molecular sieves, diatomite, and more. As early as the 1930s, people utilized activated carbon to adsorb phenolic compounds from coking plant wastewater. Thus, the application of activated carbon in water treatment has a history of nearly eight decades.

2. Activated carbon for water purification is categorized into coal-based, wood-based, coconut shell, and fruit shell varieties. Coal-based activated carbon is primarily used in large-scale water purification facilities and filter cores. Wood-based activated carbon, particularly coconut shell activated carbon, is widely applied in water purifiers. Each type of activated carbon has its own advantages and disadvantages. Coal-based activated carbon is priced lower and has a higher production volume, thus securing a favorable position in bulk purchases for water supply projects that require hundreds to thousands of tons. However, these drawbacks are not pronounced in large-scale water treatment projects due to their higher ash and heavy metal content. Nevertheless, these缺点 are more pronounced in terminal water purification, as it involves deep purification of drinking water from raw water, removing harmful impurities such as heavy metals. Coal-based activated carbon is clearly not up to the task.

3. The wood-based activated carbon for water purification is categorized into shell activated carbon and coconut shell activated carbon. This activated carbon boasts the advantages of being more cost-effective than coconut shell activated carbon and of higher quality than coal-based activated carbon. Its drawback is its lower adsorption capacity, with iodine adsorption values typically ranging from 600 to 900, resulting in lower strength, especially when iodine is used. Coconut shell activated carbon is of high grade and widely used in terminal water purification. Its benefits include strong adsorption capacity, low ash content, high strength, and good taste of the output water. The downside is its higher price. Additionally, the production process is primarily based on converter activation. The original SLEP furnace and rake furnace are largely being phased out.

What are the pros and cons of activated carbon for water purification?

1. Advantages: Made from materials like charcoal and bamboo charcoal, our activated carbon water purifier boasts a combination of physical and chemical adsorption capabilities. This enables it to selectively absorb various harmful substances from tap water, effectively removing chemical pollutants and odors, thereby enhancing our safety and health.

2. Drawbacks: Although activated carbon for water purification has a high adsorption capacity, the water quality after purification is not suitable for direct drinking and requires membrane filtration technology to meet drinking water standards. Additionally, the adsorption capacity of the purified activated carbon is limited, and it will become saturated after a certain period of time. At this point, it is necessary to replace it in a timely manner.

What is Activated Carbon for Water Purification?

Activated carbon for water purification is typically in the form of cylindrical granules, featuring a large specific surface area, well-developed micropores, high mechanical strength, rapid adsorption speed, high purification level, low dust generation, and a long service life. It is widely used in chemical, electronic, dyeing, food and drinking water, industrial water, solution filtration, adsorption purification, impurity removal, and deep purification of industrial wastewater. It effectively removes odors, chlorine, heavy metal ions, and other harmful substances while also decolorizing. The series of water purification activated carbon is made from coconut shells and is refined using advanced production technology.

Activated carbon for water purification boasts advantages such as well-developed pore structure, high strength, low impurity content, moderate particle size, low resistance, and ease of regeneration. It delivers excellent purification results, effectively removing odors and enhancing water purity. It also has a high removal rate for various harmful substances in water, such as chlorine, phenols, arsenic, lead, and pesticides. It is widely used in the filling of various large, medium, and small water purifiers. It is also suitable for the decolorization and refining of sugar and non-alcoholic beverages, as well as for purifying indoor and outdoor air. Particularly, activated carbon loaded with special components offers superior purification for harmful gases like ammonia and formaldehyde indoors.
