Abstract
A hollow fiber filter device has a filter casing which is partitioned by a horizontal member into a filtered liquid chamber and a filtering chamber and a plurality of filter modules are suspended downwardly from the horizontal member. Each of the modules includes a plurality of hollow fibers having upper ends open to the filtered liquid chamber and also having lower ends open to a liquid collecting chamber which is sealed from the filtering chamber and is arranged to communicate with the filtered liquid chamber by way of a conduit so that the full length of the fiber is utilized for filtration.
