Abstract: A preliminary investigation has been performed to determine the feasibility of conditioning a sulfite pulp mill waste activated sludge (WAS) by freezing and thawing. A series of experiments quantifying dewaterability was ...

Abstract: Studies are undertaken to assess the nature and extent of phosphorus (P) sources affecting eutrophic Black Lake, located in northern New York State. The analysis requires both field and laboratory activities. The results ...

Abstract: Limiting flux theory has become accepted in the design of secondary clarifiers, and has proven useful in the operation of existing activated sludge facilities. In this paper, the governing equations used to find the recycle ...

Abstract: Freezing and thawing transform alum sludge flocs into granular particles that rapidly settle. One objective of this paper is to help modelers and designers of the freeze/thaw conditioning process visualize the process at ...

Abstract: In recent years the advent of the anaerobic expanded bed reactor (AEBR) has made possible the treatment of wastewaters of comparatively lower strength than have been treated traditionally by anaerobic means. However, ...

Abstract: A method for determining chemical dosing based on multiple regression analysis is presented. Due to smaller operating budgets, small plants often lack the full‐time laboratory technicians and testing equipment necessary ...

Abstract: A significant potential exists to lower energy consumption and reduce sludge production by incorporating anaerobic processes into wastewater treatment trains. The specific treatment arrangement studied in this case is the ...
