Well it's not the sand; the #"filtrate"# passes thru the filter paper.

Explanation:

The sand is retained by the filter paper; here the sand is the #"filtrand"#. However, the #"filtrate"#, that which passes thru the filter paper is a solution of salt in water. Often, when we perform a filtration, we add a bit of Celite to the starting mixture, which traps insoluble materials, and allows the filtrate to pass thru the filter quickly.
