Abstract
A diffuser module and system for diffusing gas into liquid such as in aeration/mixing of wastewater. Each module has a header pipe and diffusers which receive gas from the header pipe. Each pipe is equipped with a smaller internal pipe arranged concentrically to provide an annular space which receives the gas and supplies it to the diffusers. The volume within the internal pipe can serve as a ballast chamber or a buoyancy chamber or both.
