| titleOfInvention | Apparatus and process for sewage and wastewater treatment |
| abstract | In this process, the treatment of wastewater is brought about by active biosolids which are arranged to continually fall through the liquid being treated, in a tank. Biosolids are then pumped from the base of the tank to be distributed over the tank surface. This distribution can take place from a suitable array of channels placed above the tank surface. As well as distributing the biosolids, these channels act as weirs and oxygen is dissolved in the liquid as it drops onto the liquid surface and by bubbles entrained into the surface layer of water in the tank. Because treatment is taking place in a low turbulence, settling, regime, clarification zones to remove the active biosolids from the treated wastewater before discharge, are readily created by the placement of simple baffles. A clarification zone is defined by any baffled area which does not receive re-circulating liquor from a weir channel. Treated wastewater is discharged from conventional launders placed within or around the clarification areas. There are a number of advantages from such a configuration when used for the treatment of wastewater. |
