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 header pipe is equipped with a truss for enhanced structural strength and resistance to bending. The truss may take the form of a buoyancy/ballast pipe connected with the header pipe by purlins.
