Application of Reservoir Sedimentation Data to Problems of Environmental Management
Application of sediment delivery ratios and sediment routing procedures to sediment measurements provide an alternative approach to the prediction of localized average annual erosion rates....
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...
Development of a Two-Stage Membrane-Based Wash-Water Reclamation Subsystem
A two-stage membrane-based subsystem was designed and constructed to enable the recycle of wash waters generated in space. The first stage is a fouling-resistant tube-side-feed hollow-fiber...
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,...
Wastewater Recycle/Reuse: Lessons-Learned from USA-CERL Research and Development
Ultimate acceptance of water recycle/reuse by the scientific community is a function of rigorous data collection and successful demonstration regarding health effects. An uncomplicated,...
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...
Water Supply Yields Power
During an overall renovation of the water supply system in Pittsfield, Mass. it was decided to bring water from three of the town's four reservoirs to a single treatment plant...
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...
Rehab Defies Pros, Beats Clock
Fast-tracking an overhaul of its wastewater treatment system let Columbus, Ohio escape federal penalties under the Clean Water Act. Over $200 million was invested to improve the city's...
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...
Rehab for Filtration
Not all water treatment plants currently include filtration, but standards set forth in the Safe Drinking Water Act mandate it for surface-collected potable water. Objective is removal...
