A wastewater spray distribution apparatus is operative to distribute wastewater produced by a sewage treatment system (10) onto a ground level (22) through operation of sprayers (118, 260). The exemplary sprayers include a manifold (142, 262) that includes outlet nozzles (158, 264) that can be readily removed and replaced. The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes brake (207). A brake is provided in each nozzle and is adjustable to provide brake force to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed. Alternative arrangements include manifolds including fixed or adjustable flaps and radially outwardly adjustable arms to adjust rotational properties.
B05B 3/06 - Spraying or sprinkling apparatus with moving outlet elements or moving deflecting elements with rotating elements driven by the liquid or other fluent material discharged, e.g. the liquid actuating a motor before passing to the outlet by jet reaction
B05B 3/00 - Spraying or sprinkling apparatus with moving outlet elements or moving deflecting elements
B05B 15/16 - Arrangements for preventing or controlling structural damage to spraying apparatus or its outlets, e.g. for breaking at desired placesArrangements for handling or replacing damaged parts for preventing non-intended contact between spray heads or nozzles and foreign bodies, e.g. nozzle guards
B05B 15/652 - Mounting arrangements for fluid connection of the spraying apparatus or its outlets to flow conduits whereby the jet can be oriented
C02F 9/00 - Multistage treatment of water, waste water or sewage
C02F 1/00 - Treatment of water, waste water, or sewage
C02F 1/32 - Treatment of water, waste water, or sewage by irradiation with ultraviolet light
C02F 3/20 - Activated sludge processes using diffusers

The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes a liquid tight jacket (208). The jacket isolates components which facilitate movement of a rotatable hub (154), from water passing through the sprayer and other contaminants. A brake is provided in each nozzle and includes a liquid lubricant in the jacket that operates to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed.
