What is a filtration residue?
A filtration residue is the solid substance left in the filter media(filter paper, sponge, activated charcoal, etc.)… Whenever filtration occurs when the solid substance is separated from the liquid the recovered liquid is called filtrate while the recovered solid is called residue or precipitate. It is sometimes associated with the residue left after decantaion but to be more specific some people call it filtration residue to clarify the statement.
