Abstract

To increase the liquid-proof properties and to avoid swelling expansion in a kieselguhr support element, which is produced by deposit from a slurry of untreated fibres and subsequent drying and which finds application in kieselguhr matting filtration in a filter press, 20 to 50% by weight with respect to the total fibre mass of the support element (considered dry) consists of polyolefine fibres with a fibre length of 0.8 to 1.2 millimetres. For the production of the support element, the polyolefine fibres are added to an aqueous suspension of natural material fibres, the fibre mixture suspension is deposited on a sieve belt and drained, and the layer is dried at the sintering temperature of the polyolefine fibres.
