Answer 2

WHAT IS FILTRATION : Filtration is technically defined as the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter.

MOST COMMON EXAMPLE OF FILTRATION : The most common example is making tea. While preparing tea, a filter or a sieve is used to separate tea leaves from the water. Through the sieve pores, only water will pass. The liquid which has obtained after filtration is called the filtrate; in this case, water is the filtrate. The filter can be a paper, cloth, cotton-wool, asbestos, slag- or glass-wool, unglazed earthenware, sand, or any other porous material. Filtration is used in water treatment and sewage treatment.

So, We conclude that a paper, cloth, pure-cotton wool, pure asbestos, etc. can be used as filter during the process of filtration.
