ABSTRACT:
An apparatus and method for installing a fluid dispenser (10) in a submerged relation in wastewater of a wastewater chamber (14). The fluid dispenser (10) is secured to a bracket (44) which slides along a vertical post (32) in the wastewater to a desired depth at which a stop (46) positions and blocks further sliding movement of the bracket (44) and fluid dispenser (10). Fluid dispenser (10) and sliding bracket (44) move downwardly from the upper end of post (32) and when sliding bracket (44) hits the stop (46), bracket (44) and dispenser (10) pivot relative to the post (32) to a desired position and direction of the dispenser (10). Serrated knife edges (100) on propeller (92) cooperate with serrated knife edges (112) on collar (90) on opposed sides of an orifice (106) to cut and remove any solid particles obstructing the orifice (106). Orifice (106) is adjusted by rotation of a threaded collar (90) on threaded vacuum tube (82) and secured by set screw (114) to obtain a uniform orifice size about the entire periphery of the orifice (106).
