Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
Effect of Baghdad City Sewage Treatment Effluents on Dissolved Oxygen Profiles of an Iraqi River
The paper presents measured dissolved oxygen (DO) profiles in an Iraqi river in the vicinity of Baghdad City. The effect of the effluent discharges from Baghdad Sewage Treatment Plant...
Water Supply and Sewage Disposal: Shanghai, China
This paper describes a joint research effort which took place between the Shanghai Bureau of Environmental Protection, Tsinghua University (Beijing), and the University of Michigan. The...
Alternate Sewers�No Longer Alternate
The term alternate sewers means those used where neither conventional gravity sanitary sewers will suffice, nor will the septic tank/leach field system. In such situations, usually one...
Dried Sludge for Fertilizer
Dried sewage sludge has been used as a fertilizer material for several decades in the United States. While sludge drying and fertilizer production is normally more costly than other municipal...
Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...
Oxygen Transfer Studies in Activated Sludge
A bench-scale research project was undertaken to evaluate the two-film model for predicting oxygen transfer rates in sparged suspended growth systems and to determine if interfacial oxygen...
A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
Controlling Factors in Vacuum Filter Performance
Changes in the processes at Milwaukee's Jones Island sewage treatment facilities required testing of the filterability of various mixtures of sludges. The main purpose of...
Denver's Dual Utilization Sludge Management Plan
The Metropolitan Denver Sewage Disposal District No. 1 (District) has adopted a Dual Utilization approach to sludge management. This technique uses composting during periods of inclement...
Three-Dimensional Simulation of Flow and Sewage Effluent Migration in the Strait of Juan de Fuca, Washington
The purpose of this study was to evaluate effects of a proposed sewage effluent discharge located in the Strait of Juan de Fuca just outside of Sequim Bay, Washignton. The three-dimensional,...
Design and Operation of Belt Filter Presses
This report summarizes the findings of a study performed to identify and concisely document improved design and operation procedures for belt filter presses for municipal sludge that have...
Ocean Dumping at the Philadelphia Site; A Case Study
This study reviews the results of eleven years of investigation of the impact of ocean disposal of sewage sludge at the Philadelphia dumpsite. The site, located on the continental shelf...
Beneficial Use of Municipal Sewage in the Ocean
When sewage sludges and effluents are introduced in a properly controlled manner, they can be of benefit to large areas of the ocean. For example, benthic biomass and growth rates of commercially-valuable...
Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...
Chicago's TARP Challenge?8 Million Tons of Rock
The Metropolitan Sanitary District of Greater Chicago (MSDGC) serves 122 municipalities covering 866 square miles in Cook County, Illinois. Of these cities, towns and villages, 53 have...
Sewage Plant
The Sacramento Regional Wastewater Management Program cost $460 million, took 10 years to build, and solved problems in sludge disposal, odor control, conveyance systems, combined sewer...
Steady-Site Dispersion of Pollutants in Rivers Near Sewage or Drainage Outfalls
A theoretical model is developed for determination of concentration distribution of pollutants in a river. Pollution is caused by the disposal followed by dispersion of sewage or drainage...
Hydraulic Testing of a Large Make-Up Pipeline
A 37 mile pipeline which consists of sections of 114 inch, 96 inch and 66 inch pipes was constructed for delivering secondary sewage effluents for power plant makeup. During initial operations,...
Will Reforms Improve Sewage Treatment Plant Performance?
After an exhaustive investigation, a Congressional subcommittee recommended more than 20 legislative and administrative reforms aimed at improving performance and economy of the wastewater...
