Water Main Rehabilitation Using Silicote Lining
In an attempt to find a cost effective rehabilitation alternative for over 320 miles of unlined distribution water main, the Louisville Water Company has evaluated a new rehabilitation...

Reuse and Treatment of Electrochemical Industrial Wastewater by Electrodialysis

Alkaline Sludge Stabilization Processes Offer Viable Sludge Management Options

Alkaline Sludge Stabilization: A Quick Fix and Long Term Sludge Management Option for Burlington, North Carolina

Alkali-Silica Reactivity: An Overview of a Concrete Durabilty Problem
An overview of the problem of alkali-silica reactivity (ASR) is presented. It is a chemical reaction that can occur between aggregates containing certain forms of silica and the alkaline...

Alkali Activation of Class C Fly Ash

Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...

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,...

Radionuclide Migration as a Function of Mineralogy
The migration of radionuclides is studied as a function of mineralogy utilizing batch sorption and column experiments. The transport behavior of alkaline, alkaline-earth, and transition...

Mechanistic Interpretation of Glass Reaction: Input to Kinetic Model Development
Actinide-doped SRL 165 type glass was reacted in J-13 groundwater at 90°C for times up to 278 days. The reaction was characterized by both solution and solid analyses. The glass was seen...

From Mean Fluxes to a Detailed Experimental Investigation of the Gas Transfer Process
Three new experimental techniques are discussed which allow a much more detailed investigation of the gas transfer process than any previous techniques. Using heat as a proxy tracer for...

Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....

Developing a Multiple Parameter Approach to Improve Process Control for Operating High and Low Rate Biological Nutrient Removal Systems

Use of Alkali Activation of Alumino-Silicates to Form Binders from Lunar Soil
The establishment of a permanently manned lunar base requires construction materials which can withstand the lunar environment and can be obtained from locally available lunar materials....

Properties of Sedimented Double Alkali FGD Slurries

Stopping the Cracks
It is generally agreed that reinforced concrete in parking garages especially in the deicing salt environment is exposed to unusually hostile service conditions. Deterioration of reinforced...

Phreatophyte Water Use Estimated by Eddy-Correlation Methods
Water-use was estimated for three phreatophyte communities: a saltcedar community and an alkali-Sacaton grass community in New Mexico, and a greasewood rabbit-brush-saltgrass community...

Treatment of the Wastewater From the Alkaline Cooking of Maize in an RBC System
The liquid waste resulting from cooking and washing of maize is called nejayote or nexayote. The soluble COD concentration of this waste ranges from 10,000 to 20,000 mg/l. In an effort...

The Effect of Low Level Alkalinity on Nitrification Rate

Rotating Biodisks Recarbonate Alkaline Wastewater
Lime addition to raw wastewater as an upgrading technique can significantly aid a rotating biological contactor (RBC) plant in producing effluents in compliance with federal discharge...
