摘要： One or more new, or existing, or modified, open bottom bio-remediation reactors R are contained within a commercial, industrial, or municipal waste water aeration treatment facility or tank directly above existing and/or new stand-alone diffusers located on the bottom of the facility or tank. The reactors R increase solubility of air and/or oxygen in water, increase energy efficiency, increase through put of treated waste water, and improve bio-remediation of the waste water. Also, a tube reactor having no packing substrates in a non-tube area is described.

摘要： A method is presented for biological removal of contaminants like sulfide from ground waters and industrial waters. A fixed film compartmentalized bioreactor or bioreactors are used to convert sulfide to elemental sulfur and the subsequent conversion of the elemental sulfur to sulfates. The present invention uses a packed bed bioreactor configuration that uses packing material to maximize the concentration of sulfide oxidizing bacteria.

摘要： The present invention relates to a method for degrading and inactivating at least one xenobiotic, the at least one xenobiotic being present in an aqueous medium. The method comprises the steps of (a) grafting at least one enzyme onto a solid support, (b) incubating the solid support with the at least one enzyme into the aqueous medium and (c) measuring the evolution of the concentration of the at least one xenobiotic. The method is remarkable in that the at least one enzyme is New-Dehli metallo-β-lactamase 1, a laccase extracted from Pleurotus ostreatus and/or a β-lactamase extracted from Pseudomonas aeruginosa and in that the solid support is a moving bed carrier.

摘要： The present disclosure provides a water treatment module, a bioreactor comprising one or more of such modules and a receptive water treatment system. Also provided herein is a method making use of the above module, bioreactor and system. The water treatment module comprises (i) at least one elongated gas enclosure comprising a gas inlet and two vertical walls, at least one vertical wall comprising a water-impermeable and gas-permeable membrane having a water-facing side and a gas-facing side, the two vertical walls separating between water external to the enclosure and gas within the enclosure, the gas enclosure being in a rolled or folded configuration to thereby define a convoluted horizontal path and one or more water-treatment spaces formed between opposite water facing sides of the enclosure; and (ii) a diffuser arrangement comprising gas diffusers configured for introducing a stream of gas into the one or more water treatment spaces.

摘要： A membrane biofilm reactor including a vessel defining a volume is disclosed. The reactor also typically includes a first and second plurality of hollow fiber membranes. Each hollow fiber membrane generally has an outer surface and a lumen, and is located within the volume. The reactor further preferably includes a first and second gas feedstock. The first gas feedstock is provided through a first inlet in fluid communication with the lumens of the first plurality of hollow fiber membranes. The second gas feedstock is provided through a second inlet in fluid communication with the lumens of the second plurality hollow fiber membranes. Finally, the reactor also typically includes a biofilm formed on the outer surface of the hollow fiber membranes and made up of methanotrophs, Methanosarcina acetivorans, or both. The first gas feedstock is preferably different from the second gas feedstock.
