Abstract

A filter compound material (10) comprises a first and second filtration membrane (1, 5) and a drainage material (3) arranged therebetween. The drainage material (3) and the filtration membranes (1, 5) are laminated by means of adhesive nets (2, 4). A flat filter element is made as a blank from the filter compound material and has a geometric shape adapted to the respective use.

Description

technical field [0001] The invention relates to a filter composite comprising a drainage fabric with a first and a second filter membrane laminated to the upper and lower sides of the drainage fabric, the invention also relates to It relates to a method for producing the filter composite material and a flat filter element produced thereby. Background technique [0002] Filter composite materials are known in the prior art and are used for the manufacture of flat filter elements, wrap-around filters and the like. Conventional filter systems for sewage purification comprise flat filter elements which are arranged in parallel at a distance from one another. The flat filter elements are designed as mats or cassettes in which a drainage structure designed as a flexible fabric or rigid plate is surrounded on both sides by a filter membrane. Filter membranes are usually constructed as a two-layer composite structure of a support nonwoven layer and a porous membrane layer. The re...
