Page 5 - REMOVING IMPURITIES FROM WATER AND PURIFYING IT (2)

2. FILTRATION

• In filtration, the insoluble

impurities present in water are

removed by passing the impure

water through a filter paper.

•For example, if we pass a

mixture of sand and water

through a filter paper placed in

a funnel, then water will pass Filtration

trough filter paper. This water

can be collected in a flask.

•Sand, being unable to pass

through the fine pores of the

filter paper, stays behind on

the paper.
