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...

The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...

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...

Experimental Verification of a Unified Chlorine-Ammonia Reaction Model
A model of the reacting aqueous chlorine-ammonia system is proposed which describes equally well the rapid 'breakpoint' oxidation of ammonia or the slow decomposition...

Heat Treatment and Low Pressure Oxidation Systems
A study was performed to identify problems and to document solutions in the design, operation, and maintenance of heat treatment and low pressure oxidation systems for conditioning sludge...

Biological Treatment with a Support-Aerated Biofilm

Hydrogen Sulfide Removal Systems for Digester Gas

Biochemical Oxidation of Solvent Extracted Coal Gasification Process Wastewater

Wet Air Oxidation — An Alternative to Land Disposal

Oxidative and Non Oxidative Ammonia Modeling

Maximizing Algal Yield in High-Rate Oxidation Ponds
One of the major problems in operating high-rate oxidation ponds (HROP) so as to give the maximal yield of algae is the determination of the best combination of retention time and effluent...

Uncertainty Analysis of Dissolved Oxygen Model
First-order uncertainty analysis was applied to 258 stream segments to determine the relative contributions to scatter, or uncertainty, in dissolved oxygen predictions by each of the parameters...

Effects of Ozonation on Chemical Characteristics of Sludges

Removal of Cd(II) and Hg(II) by Activated Carbon

In-Pond Separation of Algae from Treated Effluents

Swedish Experience of the Use of Thermoplastic Pipes for Water and Sewage Transport

Biological Oxidation of Coke Plant Effluent
The purpose of this study was to address some of these issues by investigation of biological oxidation characteristics of specific coke plant ammonia still effluent. Specific objectives...

Treating Industrial Wastewater of Varying Quality and Quantity

Design Verification for Tropical Oxidation Ponds
In this note the authors will present the results obtained in northeastern Brazil from a series of five pilot scale ponds each having a retention time of 5 days-7 days....
