A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.

A bioreactor interface plate assembly for attachment to a bioreactor container holding a cell suspension. The bioreactor interface plate assembly comprising a bioreactor interface plate and a filter. The bioreactor interface plate including a port formed therein for egress of fluid from the bioreactor container. The filter attached to the bioreactor interface plate in fluid communication with the port, the filter positioned to be located within an internal volume of the bioreactor container while the bioreactor container is connected to the bioreactor interface plate. The filter configured to retain cells from the cell suspension in the internal volume when the fluid egresses from the bioreactor container via the port.

A containment system consists of a set of filtering units, a first float, a second float, and a sliding mechanism. The set of filtering units is used to filter an oil spill or other hazardous material. The first float and the second float allow the apparatus to stay afloat in the water source. The sliding mechanism allows the user to control the first float and the second float and thus, control the submersion level of the set of filtering units. Each of the set of filtering units is interconnected through a first interlocking mechanism and a second interlocking mechanism. A plurality of perforated filter cartridges of the set of filtering units executes the filtering process. Preferably, the plurality of perforated filter cartridges will be removably positioned within an enclosure.

Embodiments disclosed here include a buoyant filtration system and method including a buoyant rim which may be used to encircle a pollution source and attached to a submersible wall and floor. Some embodiments include the detachable filtration systems on or near the buoyant rim. Some embodiments include a bag attached to the buoyant rim where the bag is water permeable but retains the pollution in the water.
