When solids are in small amount (less than1%) , the process is usually spoken as clarification
Filter paper is used
Talcum is used. 
Different filter media are used
No filter media is used 
Intention of filtration may be the collection of filter cake. 
Intention of Clarification may be the collection of filtrate.
