In the mathematical field of set theory, an ultrafilter on a given partially ordered set (poset) P is a maximal filter on P, that is, a filter on P that cannot be enlarged. Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable . At Ultrafilter we have a wide range of filtration products for compressed air, process and water +(0) 143975. Innovative Aufbereitungslösungen für Druckluft, technische Gase und Flüssigkeiten.

We may also define an ultrafilter to be maximal among the proper filters. This definition generalises from the power set of S to any poset L; . India to Design, Engineer, Manufature, Market Service high efficiency purification equipments . Let S be a nonempty set, then an ultrafilter on S is a nonempty collection F of subsets of S having the following properties: 1. Ultrafilter definition, Physical Chemistry. To make it into an ultrafilter it must be made as large as possible without including the empty set.

That can be prevented by not allowing any pair of disjoint sets . Ultrafiltration is a versatile and economical solution for filtering large molecular weight materials.

A pressure-driven membrane technology that separates particulate matter from solutions, helping to provide clean water at a lower cost.

The axiom of choice implies that every filter can be extended to an ultrafilter. However the implication cannot be reversed.
