Abstract: A method for treating a fluid is provided using a particulate material in the form of a deposited layer having an upstream side and a downstream side wherein a flow of the fluid is directed through the deposited layer from the upstream to the downstream side at a first temperature. The method includes reconditioning the deposited layer and then resuming treatment of the fluid, wherein reconditioning comprises heating the deposited layer to a second temperature; and cooling the deposited layer to a third temperature at an average cooling rate in the range of up to about 20° C./min.

Abstract: A filter module for dead-end and cross-flow filtration processes is provided comprising: a frame element comprising two substantially planar faces defining first and second openings at opposite sides thereof; a first and a second filter medium in the form of a sheet material, said filter media each having a first side and a second side; the first and second filter media being attachable in a fluid tight manner to the frame element and fully cover its first and second openings, respectively, a space defined and delimited by the frame element and the two filter media, said second sides of the filter media being arranged to face said space; and said frame element comprising one or more frame sections accommodating one or more ports providing a fluid flow path from said space to the exterior of the filter module.

Abstract: A filter element for use in cross-flow and dead-end filtration comprises a porous sheet material having a non-filtrate side and a filtrate side, said sheet material being arranged in a plurality of pleats extending in a longitudinal direction, each pleat having a first and second wall portion extending perpendicular to said longitudinal direction from a first, open end to a second, closed end of the pleats, the first and second wall portions being spaced apart from one another; and a non-filtrate fluid supply arrangement extending along the longitudinal direction of the pleats, wherein said fluid supply arrangement is in fluid communication with the first or second end of each pleat substantially along the whole length of the pleat, said fluid supply arrangement being provided with openings designed to provide a fluid flow from the supply arrangement into the pleats in a direction substantially perpendicular to the longitudinal direction thereof.

Abstract: A filter module is formed of wound filter material having openings wherein the boundary surfaces of the openings constitute flow-through surfaces. The openings of the wound layers of the filter material form channels angled relative to the winding axis, wherein one group thereof opens at the outer peripheral surface of the roll and the other group opens at the inner peripheral surface of the roll and wherein the channels on the other end, respectively, are closed and wherein the channels, angled relative to the winding axis, are separated from one another by filter material, and wherein the inner area of the roll has a central channel arranged around a winding axis.

Abstract: The invention relates to a module for processing a fluid having a body of wound layers of a sheet material, the body having inner and outer surfaces, first and second end faces and a passage extending along the winding axis of said body in fluid communication with the inner surface, the sheet material having openings forming at least three types of channels, the channels extending from the inner surface to the outer surface, a first type of channel being open at the outer surface of the body and closed at the other end, a second type of channel being open at the inner surface of the body, in fluid communication with said passage and closed at the other end, a third type of channel being closed at both ends thereof and positioned such as to receive fluid from one or more channels of the first or second type.
