Abstract

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.

Claims20

Dependent claims

Apparatus comprising:

a rotatable water distribution sprayer including
a base, wherein the base includes
a body,
wherein the body includes a generally cylindrical internal cavity,
wherein the cavity extends along an axis,
wherein the body includes an outlet body end, wherein the outlet body end includes an outlet body end opening,
a hub,
wherein the hub extends in the cavity and is rotatable about the axis within the cavity,
wherein the hub includes a nipple end, wherein the nipple end extends axially outside the body through the outlet body end opening, and is configured to be releasably engageable with a manifold inlet of a manifold including at least one outlet nozzle that is radially disposed from the axis,
wherein the hub includes an axial passage therethrough, wherein the axial passage fluidly extends from within the cavity through the nipple end,
a brake,
wherein the brake is in operative connection with the hub and operative to apply a selectively variable brake force that resists rotation of the hub in a hub rotational direction,
wherein water discharge from the at least one outlet nozzle is operative to produce a rotational force operative to overcome the brake force and cause the hub and manifold to rotate in the hub rotational direction.
