A filtering unit including an upper container for receiving fluid to be filtered, a lower container for receiving the fluid from the upper container and an intermediate filter cassette. The filter cassette includes a support member connected with a flat filter member, such as a membrane filter, and can be removed with respect to each of the upper and lower containers. The filter cassette may be inserted within the upper container with sealing engagement between the support member and the internal wall of the upper container. The various disclosed embodiments include the ability to serially connect multiple filter cassettes generally between the liquid contained in the upper container and the lower container.

1. A filtering unit comprising:an upper container having a wall with a first upper opening for receiving fluid to be filtered, said wall further having an inside wall surface, a lower container having a second upper opening for receiving the fluid from the upper container, and a filter cassette including a support member connected with a flat filter member, said filter cassette being configured for disposition between the fluid to be filtered in the upper container and the lower container and being separable from each of the upper and lower containers, said filter cassette configured to be received through said first upper opening and said support member including an integral resilient peripheral edge forming a seal for engaging the inside wall surface of the upper container, said edge deforming toward said first upper opening when making sealing engagement with the inside wall surface and thereby forming a selectively engageable seal between the fluid in the upper container and the lower container to ensure that fluid in the upper container passes through the filter member before passing into the lower container.
