Effects of Temperature and Mean Cell Residence Time on Enhanced Biological Phosphorus Removal
The effects of temperature and mean cell residence time (MCRT) on biological phosphorus and nitrogen removal were investigated by operating pilot-scale continuous-flow activated sludge...

The Effect of Operational Parameters on the Acid-phase Anaerobic Fermentation in the Biological Phosphorus Removal Process
A series of laboratory-scale, continuous flow experiments has been employed to study the effects of selected HRTs and SRTs on the acid-phase fermentation of primary sludge. The VFA production...

Phosphorus Transport from Delaware's Rural Watershed
Phosphorus loads were estimated for 62 watersheds. Major land uses in the watersheds were cropland and forestland. Annual phosphorus loads varied from 0.42 to 1.19 kg/ha. Watersheds with...

Hypolimnetic Aeration in Three Swiss Lakes
Eutrophication is quite common in low altitude Swiss lakes. Government agencies have set up phosphorus and oxygen limits for streams and lakes. Aeration equipment has been in use for up...

Protecting a Sensitive Ecosystem Through Advanced Treatment at the Reno-Sparks Wastewater Treatment Facility
The requirements for high degrees of nutrient removal at the Reno-Sparks Wastewater Treatment Facility required employment of several cost-effective, innovative treatment process applications....
