Title: Innovations in Wastewater Treatment by Betty-Ann Curtis
Introduction
Betty-Ann Curtis is a notable inventor based in Waukesha, WI (US). She has made significant contributions to the field of wastewater treatment, holding 2 patents that focus on improving the efficiency and effectiveness of activated sludge processes.
Latest Patents
One of her latest patents is a conditioning system for activated sludge wastewater treatment processes. This innovative process involves combining wastewater with bacteria-laden sludge in an activated sludge tank to create a mixed liquor. The mixed liquor is then separated into a clear effluent and an activated sludge stream. A portion of the activated sludge stream is pretreated in a conditioning tank before being transferred to an interchange bioreactor. This bioreactor operates in either batch or continuous flow mode, allowing for the cultivation of specific bacteria under desired growth conditions. Additionally, the process may include a sidestream reactor to effectively remove phosphates from the activated sludge stream.
Another significant patent by Curtis is focused on screening inert solids from low-yield wastewater treatment processes. This method combines wastewater with bacteria-laden sludge in a mainstream reactor to form a mixed liquor. The mixed liquor is separated into a clear effluent and activated sludge, with a portion of the activated sludge returned to the mainstream reactor. A second portion is treated in a sidestream bioreactor before being returned, and a screening device is employed to remove inert solids from the process.
