Question

Can carbon grains be used as a filter? if yes, how?



ans for class 6! ​

Answer 1

Answer:

yes

Explanation:

Activated carbon filters use a process called adsorption. Gas, chemicals and odors are trapped inside the pore structure of the carbon substrate. The air - purified from contaminants - comes out the filter.

For active carbon filtration, the filter bed consists of grain-shaped activated carbon particles (GAC = Granular Activated Carbon). The activated carbon particles have a porous microstructure with a very large internal surface. The structure is ideal for removal of dissolved substances from the water on the basis of adsorption. With the adsorption process, attachment of substances to the (internal) surface of the grains occurs.
