SYSTEM AND MEMBRANE FOR WASTEWATER-GENERATED ENERGY AND GAS

摘要

Systems and methods for producing and extracting a gas from a wastewater fluid can include multiple sheets or layers that form a composite membrane. The composite membrane can include a sandwich structure in which a dry matrix layer is surrounded by a first layer including a first immobilized bacteria and a second layer including a second immobilized bacteria. The first immobilized bacteria and the second immobilized bacteria can be configured to produce a gas from one or more compounds in a wastewater fluid. The dry matrix layer can be configured to receive the gas from the first and second layers, and the gas can be extracted from the membrane. In an example, hydrophobic coatings can be disposed between the dry matrix layer and one or both of the first and second layers. In an example, an adhesive interface can be disposed between the dry matrix layer and one or both of the first and second layers.

主权项

1. An apparatus for producing a gas from a wastewater fluid, the apparatus comprising:
a first layer including a first immobilized bacteria, wherein the first immobilized bacteria are configured to produce a first gas from one or more compounds in a wastewater fluid; a second layer including a second immobilized bacteria, wherein the second immobilized bacteria are configured to produce a second gas from the one or more compounds in the wastewater fluid; and a third layer at least partially disposed between the first layer and the second layer, the third layer configured to receive at least one of the first gas and the second gas from the first layer and the second layer, respectively.
