The present disclosure relates to modular filtration cassettes for filtering liquids including, for example, liquids used in semiconductor manufacturing. A filter housing may define a filter cavity comprising an upstream portion and a downstream portion. The filter may further comprise a filter element disposed in the filter cavity. The filter element may at least partially overlap the filter inlet on a first side of the filter element. The filter element may comprise a rectangular pleated filter with a set of pleats having a first set of pleat tips on an upstream side of the filter element and a second set of pleat tips on a downstream side of the pleated filter.

Modular filter cassette

The present disclosure relates to purification cassettes that have reinforcing features. One embodiment relates to a purification cassette with tensions members. A purification system may include a removable cassette defining a media cavity. A set of tension members may span between a first sidewall and second sidewall. The set of tension members can divide the media cavity into a plurality of lanes.

Purifier cassette

The present disclosure relates to modular purification systems using removable purifier cassettes for purifying liquids including, for example, liquids used in semiconductor manufacturing. A purification system may include a removable purifier cassette having a purifier inlet port and a purifier outlet port, and a manifold assembly. The manifold assembly can include a plurality of connection systems to that provide manifold ports to provide fluid to/from the cassette. In some embodiments, the connection systems may use connection nuts that can provide 360 degrees of thread engagement with less than 360 degrees of rotation.
