    Abstract: Hydrophobic polymer particles (e.g., granules or fragments) employed as filter media, e.g., for filtering runoff water, include an antimicrobial compound on exterior surfaces and can reduce proliferation of microbial organisms as well as sorb chemical contaminants from the water. By employing this dual decontamination action, filter systems employing such particles can improve the quality of runoff water (or other contaminated water streams) and reduce the risk presented by potentially harmful organisms.

    Abstract: A device or apparatus for contacting a liquid with a gas is provided. The device or apparatus has at least one gas inlet for introducing the gas into the liquid and a fiber housing with at least one liquid inlet and at least one liquid outlet. The fiber housing is surrounding and defining an outer bound for a plurality of fibers extending longitudinally in the fiber housing, whereby longitudinally extending interspaces are provided between the fibers. These interspaces thereby define flow passages for the liquid and gas. There is also provided a system and a method for contacting a liquid with a gas.

    Abstract: A bacteria growth device (1) for use with bacteria in a substantially liquid medium, the device (1) comprising at least one strip (5) having a surface area shaped and sized for receiving bacteria present in the substantially liquid medium and for allowing attachment of said bacteria onto the surface area of the at least one strip (5) so as to promote growth of the attached bacteria. The substantially liquid medium may be enclosed in an aerobic environment, in which case the device (1) is used to promote the growth of aerobic bacteria. Alternatively, the substantially liquid medium may be enclosed in an anaerobic and/or anoxic environment, in which case the device (1) is used to promote the growth of corresponding anaerobic and/or anoxic bacteria. Also described are an assembly including the above-mentioned device and the method associated thereto. Typically, these are used for promoting growth of bacteria destined for treating and purifying wastewater effluents which are high in biochemical demand, such as the wastewater discharges of residential and/or industrial septic/wastewater tanks for example.
