RO water plant Activated carbon

Activated carbon material is the amorphous carbon obtained through processing, with a large specific

surface area, has a good adsorption capacity for inorganic or organic substances in the gas, solution and

colloidal particles.Activated Carbon materials mainly include Activated Carbon (AC) and Activated Carbon

Fibers (ACF).As a kind of adsorbent with excellent properties, activated carbon material is mainly

determined by its unique adsorption surface structure characteristics and surface chemical

properties.Activated carbon materials have stable chemical properties, high mechanical strength, acid

resistance, alkali resistance, heat resistance, insoluble in water and organic solvents, renewable use, has

been widely used in chemical industry, environmental protection, food processing, metallurgy, drug

refining, military chemical protection and other fields.At present, modified activated carbon materials are

widely used in sewage treatment, air pollution prevention and other fields, in the treatment of

environmental pollution has shown more and more attractive prospects.[1]Activated carbon is composed

of more than 80-90% carbon elements, which is also the reason that activated carbon is a hydrophobic

adsorbent.In addition, carbon element contains two kinds of admixture: one kind is the combination of

chemical elements, mainly of oxygen and hydrogen, these elements are due to incomplete carbonized

residues in charcoal, or in the process of activation, exotic carbon and activated carbon surface

chemistry, such as by steam activation, or water vapor oxidation surface oxidation active carbon;Another

type of admixture is ash, which is the inorganic part of activated carbon.The main raw materials of

activated carbon can be almost all organic materials rich in carbon, such as coal, wood, nut shell, coconut

shell, walnut shell, apricot shell, jujube shell and so on.These carbonaceous materials are converted into

activated carbon by pyrolysis at high temperature and certain pressure in the activation furnace.In this

activation process, huge surface area and complex pore structure are gradually formed, and the so-called

adsorption process is carried out in these pores and on the surface. The size of the pores in the activated

carbon has a selective adsorption effect on the adsorbate, which is because the macromolecule cannot

enter the activated carbon pore diameter smaller than its pores.Activated carbon is a hydrophobic

adsorbent prepared by carbonization and activation at high temperature.Activated carbon contains a

large number of micropores, has a huge surface area, can effectively remove the color, odor, can remove

most of the secondary effluent organic pollutants and some inorganic substances, including some toxic

heavy metals.
