Effects of Physicochemical Factors on Asphalt Aging
A new model for asphalt oxidative aging is presented. The model proposes that the kinetics of low temperature aging in the pavement temperature range is largely governed by physicochemical...
Water Oxidation of Sludges and Toxic Wastes
Waste treatment technologies such as subcritical and supercritical water oxidation processes offer innovative alternatives to vexing sludge and toxic wastewater treatment problems. This...
Alternating Direction Oxidation Ditches?A Cost Saving Technology from Denmark
A soon to be released EPA report claims that in Denmark, small alternating direction oxidation ditches (ADOD) save as much as 70% of the cost for conventional oxidation ditches. The alternating...
Laboratory Investigations of Low Earth Orbit Environmental Effects on Spacecraft Materials
Operations in low earth orbit (100-500 km) must take into consideration the highly oxidative character of the environment. Partial pressures in the range of 10-6-10-7...
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...
Upgrading Wastewater Effluents for Water Reuse Through Photochemical Oxidations
Chromium Removal by Activated Sludge
The behavior of chromium (Cr) in a laboratory-scale, activated sludge process was evaluated. Both pH and the oxidation state of Cr were confirmed as critical parameters for evaluating...
Evaluation of Chlorine Dioxide and Ozone Preoxidation on Conventional Treatment and Direct Filtration
The renewed interest in the use of chlorine dioxide and ozone as preoxidants has focused mainly on their effectiveness on color and THM precursor removal and as disinfectants. This paper...
