The process of separating the solid particles present in a liquid or sometimes a gas while passing this liquid or gas through porous material called a filter.
Gravity filtration
Reduced pressure filtration
Suction filtration
Filtration in which the liquid passes through the filter solely under the action of gravity.
Reduced
pressure filtration
Suction filtration
Filtration in which the passage of the liquid through the filter is facilitated by applying a vacuum to the the flask where the filtrate collects.
