With the development of science and technology, every household now uses things like water purifiers. For the water purifier, many people are very curious about the activated carbon contained in it and want to know what role activated carbon plays in water purification? In this regard, I have specially collected some information. Next, I will share with you the role of activated carbon in water purification and what is activated carbon!
What is the role of activated carbon in water purification?
Activated carbon can remove residual chlorine, colloid, organic matter, heavy metals, radioactive substances, etc. contained in water. This material is the earliest and most widely used water purification material in water purifiers. The main reason why activated carbon has these effects is that a large number of pores of various shapes are formed in the activation process, and these small pores have strong adsorption.
In addition to having such a role in the water purifier, activated carbon can also be used for sewage treatment, waste gas and harmful gas treatment. Moreover, the modified activated carbon material has good desulfurization and denitration treatment effect and low investment and operation cost. Therefore, it has become the most important material in sewage treatment in China.
In addition, it also has the ability of air purification. For example, the newly decorated house can place activated carbon indoors to effectively absorb formaldehyde, xylene and other harmful substances in the air. Furniture deodorization can also be used. Activated carbon can be painted on newly bought furniture and placed in cabinets, drawers and refrigerators.
What is activated carbon?
Activated carbon is a material prepared by pyrolysis and activation of carbon containing raw materials such as wood, coal and petroleum coke. According to the shape of activated carbon, it is usually divided into powder and granular. Granular activated carbon also includes cylindrical, hollow cylindrical, hollow spherical and irregularly shaped broken carbon.

Now, with the development of modern industry, science and technology, there are many new varieties of activated carbon, such as carbon molecular sieve, micro sphere carbon, activated carbon nanotube, activated carbon fiber and so on. It is precisely because of this, such a new variety, so it is widely used.
