Inlet Chamber
Influent wastewater enters into the unit through the inlet or optional spray nozzle. The wastewater will then flow over the weir and enter into the aeration trays.
Inlet Connections
All connections 3" and smaller are FNPT couplings. All connections 4" and larger are flanges with ANSI 150 pound standard bolt circle. Flanged piping connections conform to ANSI B16.5.
Aeration Trays
Units are constructed out of stainless steel.
Once the wastewater starts to flow over the trays, clean air is blown up through 3/16" orifices that are strategically spaced in the tray. This injection of clean air will create a froth of bubbles, which generates a large mass transfer surface area. This surface area will volatilize the specified contaminants in the water.
More trays and larger sized units are used to strip the contaminants that require more residence time to reach optimal volatilization.
The water will flow through a series of aeration tray channels and then flow down through the downcomer to the next tray or water holding sump tank.
Outlet
Clean water exits the water holding sump tank through the outlet, either by pumped flow or gravity flow discharge.
