Acid Rain in the Adirondacks and an Evaluation of Fly Ash for Recovery of Acidified Lakes

Chlorine and Acid Conditioning of Sludge
Laboratory studies were conducted to evaluate the relative effectiveness of chlorination and acidity in the conditioning of selected primary, anearobically digested, and aerobically digested...

Polymer Coagulation of Humic Acid Waters
The removal of color from water supplies using alum, polymers, and alum-polymer combinations is described. Humic acid was used as the natural color colloid and the results indicate that:...

Use of Crushed Limestone to Neutralize Acid Wastes
To provide for the rational design of limestone neutralization processes, the kinetics of the chemical reactions involved were evaluated by experiment, and an analysis made of the chemical...

Limestone Barriers to Neutralize Acidic Streams
Water samples were taken for analysis and measurements were made to determine the effect of each installation on water quality at four prototype limestone barriers that had been constructed...

Acid Mine Rehabilitation Problems at High Elevations

Removal of Organic Matter by Activated Carbon Columns
This study shows that the major organic fraction in activated sludge effluent that exhibited a high adsorption in activated carbon columns is a fulvic acid-like material with a molecular...

Persistence of Virus and Bacteria in Seawater
At a temperature of 38–40° F bacterial survivals (Escherichia coli) were significantly enhanced in seawater deliberately polluted with small...

Bactericidal Properties of Chlorsulfamates
The low bactericidal potency of dichlorsulfamate and the apparent nonexistent bactericidal potency of monochlorsulfamate counter-indicate the use of sulfamate ion as a chlorine stabilizer...

Sulfuric Acid Attack on Concrete Sewer Pipe
Research was performed to determine if selected surface treatments would react chemically with the portland cement and increase the resistance of a mortar to sulfuric acid attack. Four...

Well Capacity for Continuous Permeability Variation
The results of an analysis of the relative effects of continuous, radially symmetric permeability variations on the capacity of a single artesian well are graphically presented. Such variations...

TVA Experience with Concrete Chimney Lining Plants
The condition of the concrete lining for TVA's Bull Run chimney after 15 months of operation is described together with the effects of insulation, temperature change, drying...

Dynamic Model of the Anaerobic Digestion Process
The major problem associated with the anaerobic digestion process has been its poor record with respect to process stability as evidenced by the reports of failing digesters. A dynamic...

Dialysis Separation of Sewage Sludge Digestion
The purpose was to study both stages of high-rate anaerobic digestion separately. Raw sludge fed into the acid fermentation tank provided substrate for the bacterial production of volatile...
