A filter device having filter means, in particular hollow fiber membranes, arranged in more than one filtration compartment within a filter housing. The filter device thereby allows more than one filtration process to be carried out serially and/or simultaneously within a single housing. For example a dialysis type filtration process such as hemofiltration or hemodiafiltration or hemodialysis may be carried out at the same time as an ultrafiltration process or as another hemofiltration, hemodiafiltration or hemodialysis process. The device may haves a split shell construction bonded or welded together along longitudinal seams. Internal separating walls within the housing are formed integrally with the shell portions of the housing to form adjacent filtration compartments when the housing portions are joined together.
A filter device comprising a housing, said housing enclosing at least two fluid filtration compartments, each filtration compartment comprising at least one filter membrane having a first surface and a second surface, said first surface of each filter membrane being in fluid communication with at least one fluid flow port and an outlet, said second surface being in fluid communication with at least one fluid flow port, adjacent filtration compartments being separated from each other by an internal wall, said housing comprising at least two longitudinally extending shell portions, one of said longitudinally extending shell portions of the housing describing less than one half of the perimeter of said housing.
