A filter for removing hazardous particulate matter from an aqueous flow. The filter includes a rigid support housing having an input port for the aqueous flow, an exit port for the aqueous flow, a brace to securingly engage a filter vessel for the aqueous flow, an internal seal and an external seal, and a disposable filter cartridge configured similarly to the housing and sized to be substantially entirely received within the housing and sealingly engage the internal seal and having a filter medium that extends across a path from the input port to the exit port when received in the housing, the cartridge having a terminal seal located to sealingly engage the cartridge to the aqueous flow filter vessel outside of the housing when the cartridge sealing engages with the internal seal. The rigid support housing may be installed in a filter vessel for an extended period and held in place by the brace, and repeatedly during the extended period, a disposable cartridge may be installed within the housing to seal the cartridge to the filter vessel, aqueous flow may be directed through the filter medium, and the cartridge may be removed and discarded.

Disposable media filter

A filter adapter and filter cartridge for a filter assembly for removing particulate matter from an aqueous flow by means of a filter vessel having a support housing, a removable top, an input port for the aqueous flow, an exit port for the aqueous flow and an internal seal. The filter assembly includes a filter adapter configured similarly to the housing and sized to be substantially entirely received within the housing and sealingly engage the internal seal of the housing. A filter cartridge is configured similarly to the filter adapter and is sized to be substantially entirely received within the filter adapter and to simultaneously engage the filter vessel top and sealingly engage the filter adapter outlet. A biasing spring is located between the filter cartridge and the filter adapter. Securing the filter vessel top to the filter vessel housing causes the filter cartridge to simultaneously compress the biasing spring in the filter adapter, form a seal with the filter adapter outlet, and form a seal between the filter adapter and the internal seal of the filter vessel housing, whereby the filter adapter may be installed in the filter vessel for an extended period and repeatedly during the extended period, the filter cartridge may be installed within the filter adapter to seal the cartridge to the filter adapter and the filter adapter to the filter vessel, aqueous flow may be directed through the filter medium, and the cartridge may be removed and discarded.
