Answer :

Sr.No.
Filtration
Clarification
1 It is the separation of an insoluble solid from a fluid or gas by means of a porous medium that retain the solid but allow the fluid to pass.
When the solid are present in very small proportion i.e. not exceeding 1.o% the process of its separation is known as clarification.
2 Different filter media are used
No filter media is used
3 Intention of filtration may be the collection of filter cake.
