ABSTRACT:
In grid-type aeration systems with diffusers mounted and spaced longitudinally along air distribution conduits that are submerged in wastewater and secured to and above the floors of aeration tanks, such conduits are provided with couplings having first and second matingly compatible coupling sections of synthetic polymeric material adapted for relative rotation with respect to each other, at least one locking projection having a fixed position with respect to one of the coupling sections, and a locking receptacle array including locking receptacles having a fixed position with respect to the other coupling section. The projection and receptacles are relatively moveable in the coupling for motion from a non-engaged condition to an engaged condition during make up of the coupling. During make up of the couplings an installer may cause relative rotation of the conduits to align the diffuser gas discharge surfaces substantially horizontally and, with the couplings in made up condition, positively lock the conduits against relative rotation to maintain the gas discharge surfaces in alignment.
