Becoming Greener with Green Sand: An Iron Castings Company Devises an Environmentally Friendly Liner System Reusing Foundry Byproduct
Metalcasting is one of the oldest methods of recycling—humans have a few millennia worth of experience with the technique—but today's industry still battles public preconceptions...

Design of Municipal Wastewater Treatment Plants
Fully revised and updated, this three-volume set from the Water Environment Federation and the Environmental and Water Resources Institute of the American Society of Civil Engineers presents...

Chemical Grouting
Chemical grouting is used in underground construction primarily on soft-ground shafts and tunnels in an effort to control cohesionless or running ground conditions by modifying the soil....

Heave Distress Problems in Chemically-Treated Sulfate-Laden Materials

Coupling Physical, Chemical, or Biological Methods for Innovative Groundwater Remediation Coupled Polymer Floods and Bio-Chemical Remediation Techniques for Enhanced Groundwater Treatment
Many groundwater remediation techniques are designed to remove or destroy contaminants in situ, but these goals can be accomplished only by...

Redox Balance of Upper Mystic Lake and Effects on Cycling of Watershed-Derived Metals

Nanotechnology Takes Roots
Nanoscale particles of zero-valent iron with a trace of noble metal catalyst are punching well above their weight in the area of environmental remediation. Their ability to destroy a wide...

Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...

Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...

Thermal Cyclone Washing for Remediation of Petroleum Contaminated Soils
Thermal Cyclone Washing (TCW) is a soil remediation technology developed and tested at the University of Alabama in Huntsville. TCW is a combination of thermal, chemical, and physical...

Characterization of Anaerobic Microbial Consortium Response to Thiol-Reactive Compounds
The activity of anaerobes in wastewater treatment processes can be limited when a toxicant enters the system. For certain toxicants, along with the decrease in metabolic activity, an efflux...

Countering Chemical and Biological Terrorism
Prior to the terrorist attacks of September 11, building protection related to terrorism primarily focused on the threat of bombs detonated inside vechicles. However the September 2001...

Clean Water at the Crossroads
Thirty years after the passage of the Clean Water Act, the quality of effluent from the nation's wastewater treatment plants has improved considerably. However, much of the...

Multifaceted Trenchless Rehabilitation at the Middletown, Ohio WWTP
This paper describes the multiple trenchless technologies that were evaluated and the ones that were applied to the rehabilitation of a 78la diameter corrugated metal influent line and...

Air Stripping and Aeration

Fluid Flows and Reactive Chemical Transport in Variably Saturated Subsurface Media

New Concepts in Structural Strength Assessment for Large Buildings in Fire
This paper presents theoretical descriptions of the key phenomena that govern the behaviour of composite framed structures in fire. These descriptions have been developed in parallel with...

Rain and Gray Water Reuse Systems: The Hazard of Legionaries Disease
The Legionaries Disease is being more and more diagnosed. This infectious disease occurs when humans come in contact with the aerosol of contaminated water. The body of knowledge is growing...

A Whole New Experience
Experience Music Project co-founders Paul Allen and Jody Allen Patton wanted a new museum/interactive music facility for Seattle that reflected the creativity of Jimi Hendrix. In architect...

Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...
