Abstract:
A device to treat influent, comprising:a basin having a bottom;an influent gate housing having a bottom portion mounted in said basin to receive said influent;at least two downwardly angled influent baffles mounted inside said influent gate housing, whereby said influent flows over said influent baffles and said influent baffles create turbulent flow and aeration in said influent;an influent gate bottom mounted in said basin under said influent gate housing, whereby influent exiting said bottom portion of said influent gate housing is directed laterally; anda pre-react zone director having a lower portion at least partially surrounding said influent gate housing, said pre-react zone director defining a main react zone inside said basin, but outside said pre-react zone director, wherein said lower portion of said pre-react zone director is spaced apart from said bottom of said basin and defines a contact zone between said lower portion and said bottom, whereby said pre-react zone director directs flow of said influent in a laminar fashion through said contact zone and into said main react zone;whereby said influent avoids disturbing any settling sludge in said main react zone and forms a supernatant by filtering through said settling sludge; andwhereby settling, aerobic processing, anaerobic processing, and filtering are all performed in a single basin.
