Provided is an improved filtration module assembly comprising a vessel having a filtration cartridge disposed within it and a header coupled to an end of the vessel, the header including a housing having an open-ended upper end and a lower end, and an end cap including a portion that mates with a complimentary structure defined by the inner all of the open ended upper end of the housing to removable engage with the housing and the end cap may further define a passageway for fluid to flow out of the vessel. The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

A filter device may include a housing including a first housing part and a second housing part which define a chamber through which a fluid is flowable. The device may also include a filter insert arranged in the housing and configured to filter the fluid. The filter insert may include a seal. The second housing structure may be configured as a web. A circumferential section of the second housing structure may include a contour. The contour may include a recess configured as an interruption in an area of the web. The device may further include a support element arranged on the filter insert interacting with the second housing structure in an area of the contour. The second housing structure may press the first sealing surface against the first housing structure via the support element to seal a clean side from an unfiltered side.

A passive device for controlling rain water runoff. The device including: an inlet for directing the rain water runoff; and a mechanism for directing a predetermined initial amount of the rain water runoff to a first outlet and passively directing a subsequent amount of the rain water runoff to a second outlet.
