Hydraulic Transients in Two Acid Transfer Lines

Fly Ash and Alkali-Aggregate Reaction

Effect of Alkalinity on Copper Corrosion

A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....

Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...

Effect of Fly Ash and Silica Fume on Alkali Silica Reactions

Acidity and Chemistry of Arizona's Snowpacks
Acid snow, the frozen version of the acid rain phenomena, has been sampled in several western states, e.g., California, Nevada, Montana, and Oregon. Measurements of snowpack acidity in...

Storm Drainage Channel Rehabilitation
30 km (19 miles) of existing concrete lines storm drainage channels were studied due to repeated failures. Alternate failures causes were hypothesized and evaluated. Physical testing was...

Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...
