  • Patent number: 7678273
    Abstract: A filter unit includes membrane plates placed together parallel to one another, which at least in zones around connecting elements for the purpose of draining permeate are connected together liquid-tight. The membrane plates because of their shape and after two membrane plates have been placed one on top of the other are provided for manufacturing a liquid-tight connection or a seal by welding. As a result unfiltered liquid flows through between the membrane plates and contamination of the permeate within a volume situated between the connecting elements is prevented. Over a number of connecting elements and zones located in between it is possible to attach a hollow profile, which is closed-off at its ends. This hollow profile in a liquid-tight manner surrounds discharge openings of the connecting elements and the zones located in between with positive material engagement.

  • Patent number: 6951286
    Abstract: A showerhead assembly includes a filter that is removably receivable by the showerhead. The showerhead includes a receiving opening defined within the downstream face of the showerhead, which opening is functionally adapted to receive the filter within it. The opening of the showerhead is interposed between the water inlet and water outlet of the showerhead and within the flow of water through the showerhead such that, when a filter is inserted into the opening, all water flowing through the showerhead also flows through the filter. The filter is readily insertable within the opening and it is easily removable from it. The filter includes means for securing it within the opening when the filter is inserted.
