An Innovative Biological Nutrient Removal System

Fluidized Bed for Biological Wastewater Treatment
The fluidized bed system is a new method for the biological removal of carbonaceous BOD, nitrification, and denitrification of wastewaters. The theory developed provides a method for determining...

Energy Conservation in Activated Sludge Systems
Various activated sludge systems were evaluated for a new wastewater facility for Deland, Fla. on the basis of energy requirements and capital cost. Aerator turndown and energy savings...

Quality in a Florida 1—, 2? and 3? Stream System

A Streamlined Approach to Biological Nitrogen Removal

Largest Rotating Biological Contactor Plant Also First to Remove Nitrogen
Orlando, Florida is now constructing a new advanced waste treatment plant that removes both nitrogen and phosphorus to a high level. The plant is notable because it is the largest rotating...

The Place of Land Treatment of Wastewater in Today's Society
Land treatment of sewage can be a viable alternative to secondary and/or tertiary in-plant treatment. Depending on local conditions, overland-flow, low-rate, or high-rate systems, or a...

Denitrification Using Thiosulfate and Sulfide
Autotropic denitrification using enriched cultures of Thiobacillus denitrificans was investigated. Thiosulfate and sulfide were used as electron...

Optimization of Denitrification Process
A denitrification system composed of a completely stirred tank reactor (CSTR) followed in series with a plug flow reactor (PFR) was tested in order to minimize the disadvantages of each...

Fate of Nitrogen in Sewage Effluent Applied to Soil
Natural chemical and biological reactions will remove nitrogen from sewage effluent applied to soils if the wastewater is applied in a carefully managed treatment system. Only denitrification...

Biological Denitrification and Phosphate Removal
The objective of this study was to evaluate the feasibility of a simplified system for processing sanitary wastewater for nutrient reduction, using a submerged filter, an aeration basin,...

Process Kinetics for Denitrification
Kinetic equations describing biological growth, substrate removal, and oxygen utilization with the activated sludge process were modified and used to describe the corresponding phenomena...

Evaluation of Anaerobic Denitrification Processes
Nitrified municipal wastewater effluent was passed upward through an anaerobic filter containing gravel media to effect denitrification. Using methanol as a supplementary carbon source...

Nitrogen Removal by Modified Activated Sludge Process
A modified activated sludge process called contact-stabilization-denitrification makes it possible to eliminate 80% to 90% of the incoming total nitrogen in addition to the usual BOD removal....
