摘要： In a filter bed (11) for the solid/fluid separation of media which contain substances that attack or dissolve cellulose, for example cellulase-containing enzymes, a matrix comprising a fibrous material structure of polyolefin fibrid particles (12) which are matted and anchored in one another and which can additionally contain up to 20% by weight of narrower fibrid polyolefin fibres and/or polyolefin fibres that have a fibre length of up to 5 mm. and have just started to fibrillate, in order to strengthen the sheet formation of the matrix. The actual filter-active particles, in particular kieselguhr particles and/or perlite particles having grain sizes of 5 to 100 um., are embedded in the cellulose-free fiber matrix.

摘要： To simplify the assembly of filter modules 10, the supporting tube 1 which carries the filter cells 9 is constituted in two pieces. Both the upper tube piece 4 and the lower tube piece 5 contain locking elements 7 which are received in correspondingly large recesses 8, thereby making possible a safe interlock as well as a relative axial movability of the tube pieces 4 and 5.

摘要： A regenerable deep bed filter element and method for making it, the element being provided as a closed system, in the case of which a deep bed filter (21), disposed inside at least one hollow-cylindrical chamber (17), is formed by a bulk material filling of regenerable, filtration-active substances of a particulate and/or fibrous structure. The hollow-cylindrical chamber accommodates radial flow by means of porous inner and outer peripheral walls (18, 19). The deep bed filter can be either washed, or regenerated by flushing back with water, steam or chemical cleansing agents, during which the filtration-active substances remain inside the chamber (17).
