Abstract
Described is a through-flow cup which can be filled with a granule material and through which a liquid to be treated can flow, having side walls and sieves which are disposed at the ends thereof and by means of which the liquid can flow through the granule material in the interior of the through-flow cup and the granule material is substantially non-losably held. To improve such a through-flow cup to the effect that the incoming flow of liquid and at the same time any discharge flow of gases are offered the lowest possible level of resistance, it is provided in accordance with the invention that at least one sieve has a flat textile article in which plastic fibres of at least two different kinds are connected together to form a hybrid, wherein the one kind of plastic fibres contains hydrophilic components and the other kind of plastic fibres contains hydrophobic components.
