  • DIFFUSER ASSEMBLY FOR USE IN WASTEWATER TREATMENT
    Publication number: 20260138100
    Abstract: 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.
