An exemplary wastewater treatment system includes a pipe, a diffuser mount, and four disc diffusers. The diffuser mount includes a mount-to-pipe connection portion attached to the pipe, four distribution conduits arranged in a cross shape and in gaseous communication with the mount-to-pipe connection portion, and four curved mount-to-diffuser attachment slots located above the four distribution conduits. Each of the four disc diffusers occupies one of the four curved mount-to-diffuser attachment slots and is attached to one of the four distribution conduits. Configured in this manner, each of the four disc diffusers is in gaseous communication with an interior of the pipe and can be used to generate plumes of bubbles in wastewater for aerobic wastewater treatment applications.

Embodiments disclosed herein provide systems and methods for water aeration in a tank or other body of water that a specialized coupling assembly and flexible hose connectors rather than the commonly used rigid connector elements. The coupling assembly and flexible hose connectors utilized in the aeration grid system provide a more cost effective and flexible system that allows almost limitless configurations of the diffuser elements, depending on the intended application. Further, the coupling assembly and flexible hose connectors enable use with a wide variety of air supply pipe diameters without the necessity of providing a fitting or adapter for each pipe opening. The capability of the aeration system to be readily adapted to different sizes of treatment tanks or ponds, for example, allows the installation and use of a more flexible, prefabricated, or modular, and ultimately more efficient aeration system.

A bubble generator including a container having a side wall and a top wall defining a cavity. An insert is located within the cavity defining a gas path with a trap portion. The gas path being in communication with an exit in the container. The cavity including an opening receiving a gas accumulating within the cavity, the gas path allowing the accumulating gas to escape through the exit once the accumulating gas reaches a predetermined level proximate the trap portion.

Disclosed herein are devices, systems, and methods for water aeration and/or circulation, including, but not limited to, floating, onboard renewable energy-powered aeration for aquaculture ponds and/or other man-made and/or natural bodies of water (e.g., tanks, farm ponds, and reservoirs). In at least one embodiment, an aeration system has one or more photovoltaic (PV) panels to provide power to the aeration system. In at least one embodiment, the aeration system captures wind energy as an optional secondary power source. The aeration system may be either a battery-power or a direct-power system. The aeration system may also provide programmable settings. The system can be modular and scaled and/or customized to fit user needs. The aeration system may also include one or more float modules having an internal cavity, one or more pontoons and/or pontoon accessories for blocking and/or directing air and/or water flow, and/or one or more novel diffusers.
