Title: Wastewater treatment process and apparatus
Inventor: MACLAREN DAVID S
IPC: C02F3/28
Filed: 1993-02-03
Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber, a biofilm-aeration chamber and a settling chamber. Biofilm grows on biofilm support structure which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination of sufficient fluid flow, and reduced size suspended organic particles results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestive process than conventional processes producing no sludge. Further, resulting treated effluent has a high dissolved oxygen content and low BOD and SS. The apparatus and process has the following advantages: low MLSS concentration, short biofilm incubation time, no clogging of the system, good response to shock loading, high DO in the effluent, consistent effluent quality, sludge is eliminated, wastewater treatment duration is shortened, the process is not temperature sensitive, plant design is greatly simplified, plants of the present invention are small by comparison to conventional plants, the present invention can be a significant step in the treatment of drinking water, energy consumption during treatment is low, the present invention is very cost effective, the process permits other purification processes to be used and the process is volumetrically and BOD insensitive.
