Abstract:
1. An apparatus for treating fluid, the fluid comprising water and wastewater, comprising: a) an L-shaped enclosure adapted for being sealed; said enclosure having a horizontal foot portion and a vertically extending upright portion, and an internal area extending throughout said portions; b) a sludge digester within said upright portion for digesting pollutants; c) an inlet port for said fluid on a first side of said upright portion adjacent a top thereof and an outlet port disposed below and spaced from said inlet port of said upright portion for the fluid to be inlet into said enclosure and outlet from said enclosure, respectively; d) a fluid strainer disposed internal said enclosure between said inlet and outlet ports so that the fluid is strained as the fluid is inlet into said enclosure; e) said foot portion forming a base for an air supply for supplying air through a second side of said upright portion to an air inlet conduit at a top of said sludge digester, and an air filter for filtering said air supply, f) an ozone generator mounted on said foot portion adjacent said air supply for injecting ozone into an air intake to a blower supplying said air to said sludge digester, g) a side opening in said sludge digester for receiving said fluid, said sludge digester having an aeration chamber in which flowing air and fluid mix; and h) said sludge digester being constructed and arranged so that said fluid along with an aerating mixture of air and ozone are upwardly flowing and pass out through a digester outlet port at an upper end of said sludge digester surrounding said air inlet conduit, said exiting mixture impinging on concentric ridges surrounding said inlet conduit above said digester outlet port so that solids in said fluid are forcefully impacted to break larger solid particles into smaller particles to facilitate removal of fats, oils and greases by oxidation; whereby i) said fluid substantially cleansed of fats, oils and greases by oxidation exit said enclosure through said upright outlet port for discharge into oil/water separators, lift stations or municipal sewer systems.
