Abstract: The present invention provides a hydraulic mixer inlet for a septic or interceptor tank. The hydraulic mixer has an inlet for receiving organic containing liquid such as sewage from a source disposed in a first plane; and an outlet disposed in a second plane, the outlet fluidly communicating with the inlet by way of a pipe, the pipe having an upper surface and a vented orifice located on the upper surface; wherein an angle is disposed between the first plane and the second plane allowing for flow deflection resulting in increased mixing.

Abstract: The invention provides an assemble-on-site system for collecting biogas from digesting sewage. The system comprises a biogas deflection assembly configured and sized to fit a primary treatment unit; and a collection interface assembly operatively associated with the biogas deflection assembly and configured for connection to a biogas capture or collection system. When installed in the primary treatment unit, the biogas deflection assembly is substantially submerged and provides for the deflection of biogas to point(s) of biogas collection in the collection interface assembly. Also provided are components of the system and kits comprising one or more of the system components and assembly instructions.

Abstract: The invention provides a primary treatment unit and system for the collection of methane-containing biogas from sewage. The primary treatment unit is configured to separate sewage settling and sludge digestion into separate regions or chamber of the tank. The settling region is adapted to receive the sewage and output liquid effluent and the digestion region is adapted to receive solid components of the sewage from the settling region and output methane-containing biogas substantially generated in the digestion. The primary treatment unit is designed such that the methane-containing biogas is outputted without coming into substantial contact with sewage scum. The system further comprises a biogas collection system configured to receive the methane-containing biogas from the digestion region of the primary treatment unit.

Abstract: A biogas capture and/or collection system is provided and comprises one or more biogas capture and/or collection units (BCCU) that capture and/or collect biogas generated in one or more biogas generating chambers (BGC). The BCCUs maybe tubular conduits operatively linked to the BGCs or canisters removably linked with the BGCs and designed for reversible capture of the biogas generated therein. A waste input system operatively linked to the BGCs is used to feed waste from one or more sources of waste thereto. Biogas generation within the BGCs is optionally promoted by retention of at least part of the waste within for a time period sufficient for release of gases due to degradation or by using means for promoting microbial processing such as heating means, centers for applications not limited to electricity production, use as fuels and use for chemical synthesis. The gas utilization centers maybe located either locally at the individual sources of waste or at a centralized location.

Abstract: The system comprises one or more of the following: primary treatment units, flexible pipes, and optionally, one or more pumps. The system is designed and installed in a manner that enables the flow of liquid to be predominantly due to gravity, although one or more pumps may optionally be included at key positions. The system can be sealed and pressure tested in order for optimal performance to be achieved during operation.
