Optimizing the Activated Sludge Process by Encouraging Futile Cycling
A study was conducted to demonstrate that cell yield in activated sludge processes can be decreased without increasing oxygen consumption by applying operating conditions that encourage...

Mass Balance Analysis of Decomposed Refuse in Laboratory Scale Lysimeters
Decomposition of shredded municipal refuse was studied under laboratory conditions with leachate recycle and neutralization. Cellulose and hemicellulose accounted for 91% of the methane...

Comparison of Centrifuge Performance on Oxygen Activated Sludge
This paper compares the performance of centrifuges processing high purity oxygen activated sludge with units processing conventional activated sludge. Comparisons are made both for thickening...

Water Quality Assessment in a Stochastic Stream Environment
Methodologies are presented within this article to aid in the quantification of the uncertainty in the management of stream water quality. Specifically, means are developed for: (1) establishing...

Simulation of Oxygen Dynamics in the Vadose Zone
A microcomputer model VIP (Vadose Zone Interactive Processes) was developed as an extension of the RITZ model to provide a mathematical description of land treatment systems for the disposal...

Sediment Processes and the Houston Ship Channel
A year-long field and laboratory study of sediment oxygen demand was conducted on the Houston Ship Channel. The primary objective of the work was to better understand the processes controlling...
