Filtration separation method

This is a more common method of separating an insoluble solid from a liquid. An example
of such a mixture is sand and water. Filtration is used in water treatment plants, where
water from the river is filtered to remove solid particles.

Here is a basic lab setup for filtration:
filtration of mixtures

This process involves the use of a filter paper placed in a filter funnel. The funnel is placed
in a beaker and the mixture of water and sand is poured into the funnel. The liquid part
drains through the filter paper into the beaker, leaving the solid sand particles trapped on
the filter. In filtration, the liquid part collected is called the filtrate and the solid bit that
remained on the filter paper is called the residue.
