Energy/Environment Opportunities for Civil Engineers
In the West, Nuclear Facilities Decommissioning; In the East, Implementation of Waste to Energy Systems
The papers in this book examine and provide illustrations for civil engineering opportunities in resolving apparent conflicts between needs for energy generation and environmental acceptability....

Disposal and Utilization of Electric Utility Wastes
The papers presented in this book summarize the recent developments in coal ash utilization technology, and the current issues and regulations associated with the environmental effects...

Leaching of Nitrate from Freely Drained?Irrigated Fields Treated with Municipal Sludges
A municipal sludge land application experiment was initiated in 1975 near Riverside, California. From 1975 to 1983 sludges from the Los Angeles Metropolitan Area were applied on experimental...

A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...

Inflatable Form Construction in Space
In 1973, NASA launched Skylab 1 using a modified third stage of a Saturn V Rocket. This orbital workshop proved to be a success even though problems occurred. This article discusses the...

Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...

The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...

Supercritical Water Oxidation: Space Applications
The process of Supercritical Water Oxidation (SCWO) is approaching terrestrial commercialization for the destruction of toxic and hazardous waste chemicals. The technology appears promising...

Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...

Plasma Reactor Waste Management Systems
The University of North Dakota is developing a plasma reactor system for use in closed-loop processing which includes biological, materials, manufacturing, and waste processing. Direct-current,...

Space Operations - Care and Handling of Remains
On earth, effective methods have accommodated all functional and operational facilities and entities necessary for the handling of human remains. None have been overlooked or omitted....

Burning Coal's Waste
Culm is the waste coal and shale left behind in mountain-size piles when anthracite mining ceased in northeastern Pennsylvania. Owners of a cogeneration plant now under construction near...

Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...

Environmental Health Programs of the USEPA
The major programs of the U.S. Environmental Protection Agency (EPA) designed to reduce risk to public health are summarized with emphasis on their content, funding and effectiveness in...

Zapping Hazwastes
Electromagnetic energy, applied in situ, successfully removes contaminants entrapped in soil by vaporizing them. Recent test using radio frequency have successfully removed up to 99% of...

Garbage Management in Japan: Leading the Way
Excerpts from a book that details how land-poor Japan has less garbage problems than the land rich United States. Chapter Six, Incineration, is excerpted. In Japan, incineration is regarded...

Jet Grouting: The Pace Quickens
Over the past year, use of jet grouting in the U.S. has nearly quadrupled. A versatile tool, it has performed well in settings as diverse as a railway tunnel, industrial waste site and...

New Clarifiers Help Save History
By using clarifiers to upgrade a waste treatment plant, Camp Dresser & McKee were able to utilize the available space so that an historic building existing within the plant could...

Aeration
A Wastewater Treatment Process
This manual summarizes current aeration practices in wastewater treatment, and includes both theoretical and practical guideline for the design and operation of such unit processes. The...

Swirl Concentrators Revisited. The American Experience and New German Technology
The Swirl Concentrator is a small, compact, 'no moving parts' solids separation device. Its function is to act as as a static combined sewer overflow (CSO) regulation...
