It depends on what was in the solution that was filtered. About as specific as we can get with the information given is "insoluble stuff".
residue
Filtration is a process used for separating the components from a mixture of immiscible substances.However different kinds of mixtures require various separation techniques and filtration is one such process. When filtration is done using a suitable filter (like a filter paper)the solid matter left on the filter paper can be called the residue and the liquid countertpart is the filtrate
You think probable to petroleum coke.
The white residue is calcium and magnesium(hard water). When heated in the dishwasher it dries and leaves a chalky residue on glassware. There is a new product out that solves this problem once and for all. Its called the dishwasher filtration system and you can get it at www.dishwasherfilter.com.
add water, glucose only will dissolve, filter and evaporate water to get glucose. after filtration, the residue will be silver chloride
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.
If you think to filtration sand is a residue.

residue
Resulting substance that goes down after filtration is the filtrate and the one that remains on the filter is residue.

what is left on filter paper when using filtration? it is residue

Wood, grasses, agricultural residue, recovered paper etc.
Suspension will have residue after filtration, but solution will not.
We use filtration when we want to separate a solid and a liquid. e.g. chalk and water The residue left behind at the filter paper will be chalk in this case, for it is a solid:)
