The invention relates to a textile reinforced membrane filter wherein the membrane filter material and the textile reinforcing material are made from synthetic polymers of the same substance class. A method for the production of the textile reinforced membrane filters where the first contact time between the filter solution film and the textile reinforcement material is maintained between 0.1 and 15 seconds.

The invention relates to porous membrane filters, specifically mirco- and ultraporous membrane filters, which have fluid-impermeable areas as a result of a change of their structure on one side of the membrane to a film-like state (film-formation). These filters are, for example, very suitable for an assembly in filter cartridges according to the pouring method, because they still have on the side opposite to the filmed-up side a porous structure, which offers an ideal anchoring possibility for penetrating liquid resin.

Fluid-impermeable areas on porous membrane filters and their application

Incompletely condensed aldehyde resin having a large surface area and formed in the presence of large quantities of water under mild conditions is used for removing waste products, such as urea, from the blood in hemodialysis or for removing such impurities from swimming pools or aquariums.
