Metal Hydroxide and Metal Oxide Enhanced Activated Sludge: An Industrial Strength Wastewater Treatment Process
Canada Explores Sludge-to-Fuel Process
From Sludge to Brokered Biosolids
At the end of June, a sludge filled barge pulled away from New York harbor for the last time. It traveled more than 100 mi offshore, where workers unloaded some of the 355 dry tons of...
Waste Glass and Sewage Sludge Frit Use in Asphalt Pavements
Radiation Energy Treatment of Water, Wastewater and Sludge
A State-of-the-Art Report
Since ionizing radiation is one of the more technologically advanced forms of energy available to society, it has been applied to a great many activities such as: the sterilization of...
Gabions and Geogrids
The century-old gabion concept can be improved upon by adding geogrid reinforcement to the soil embankments the gabion wall is designed to support. The grids add stability to the embankment...
U.S. Sludge Digesters: From Pancakes to Eggs
Egg-shaped anaerobic sludge digesters, used extensively in Germany and Japan, cost more to build, but provide better mixing of sludge, require less maintenance and less energy to operate,...
Fracture Grouting with Bentonite Slurries
Stabilization and Fixation Using Soil Mixing
Hydrogen Generation During Treatment of Simulated High-Level Radioactive Waste with Formic Acid
Physical Mechanisms Contributing to the Episodic Gas Release from Hanford Tank 241-SY-101
Initial Comparison of Leach Behavior Between Fully Radioactive and Simulated Nuclear Waste Glasses Through Long-Term Testing. Part 1. Solution Analysis
Criticality Safety of TRU Storage Arrays at the Waste Isolation Pilot Plant
Sludge Dewatering in Freezing Beds
This paper summarizes the results of laboratory and pilot scale studies on the development of the sludge freezing bed. Laboratory studies indicated that a freezing bed could dewater up...
Formic Acid Requirement for Savannah River Site Defense Waste Processing Facility Melter Feed Preparation (U)
The Westinghouse Savannah River Company (WSRC) will vitrify the high-level radioactive waste into a borosilicate glass wasteform using a slurry-fed, joule-heated melter. Formic acid is...
The Processing of Simulated High-Level Radioactive Waste Sludges Containing Nitrites and Mercury
The reaction of formic acid with simulated alkaline sludge containing mercury and nitrite was studied in an engineering-scale facility. Quantification of offgas production was performed,...
Building a Geographic Information System (GIS) for Siting New York City Sludge Management Facilities
Siting studies for waste facilities usually focus on a particular geographic region, or a defined study area, and are restricted to a specific technology. However, the siting of land-based...
NOAA'S Monitoring of Ocean Dumping at the 106-Mile Dumpsite
The Ocean Dumping Ban Act of 1988 amends the Marine Protection, Research and Sanctuaries Act of 1972 to provide for cessation, by December 31, 1991, of all U.S. ocean dumping of industrial...
Responses of Benthic Macrofauna to Phaseout of Sewage Sludge Disposal in the Inner New York Bight
From 1924 through 1987, sewage sludge was dumped at the '12 mile site' 22 km off northern New Jersey in the inner New York Bight. Inputs in the early 1980s were,...
Halifax Harbour Clean Up?A Research Perspective
The status of scientific research pertaining to the marine environmental aspects of the discharge of sewage effluent into Halifax Harbour, Canada is reviewed. The background to the local...
