Correlation of Fractional Foam Coverage with Gas Transport Rates
Because breaking waves are believed to increase the flux of gases across the air/sea interface, it may be possible to correlate air/sea gas transport velocities with whitecap coverage....

Status of Integrated Performance Assessment of the Waste Packages and Engineered Barrier System
Performance assessment of the engineered barrier system for a nuclear waste repository combines information from relevant disciplines and predicts the net long-term performance of the...

Mass-Transfer Analysis of Waste Packages Containing Defense Waste Processing Facility Glass as a Waste Form
The fractional release rates of selected radionuclides from waste packages containing Defense Waste Processing Facility (DWPF) glass are calculated using the AREST code, assuming a continuous-diffusive...

Soluble High-Level Waste Decontamination and Disposal at the Savannah River Site
The high-level radioactive waste that has accumulated at the Savannah River Site is stored in large underground steel tanks. Programs to remove the soluble waste from the storage tanks,...

Nonionic Surfactant Solubilization of Polycyclic Aromatic Hydrocarbons in Aqueous and Soil/Water Systems

Evaluation and Modeling of Soluble Manganese Removal by Oxide-Coated Dual Media Filtration

Solubilization of PAH Compounds in Surfactant Solutions

Soluble Pollutant Enrichment in Snow Covers
A mathematical model is presented to simulate enrichment of soluble pollutants in snow covers. The model is based on the liquid water flow, heat transport, and pollutant transport equations....

Implications of Soluble Microbial Products (SMP) Formation on Biofilm Reactor Performance
The objective of this study is to evaluate the implications of SMP formation for biofilm treatment. To do so, the extended steady-state model was applied to predict effluent concentrations...

A Modified RBC Design: Performance Evaluation
An RBC (rotating biological contactor) system was designed using Pall rings type 40, and tested under high organic surface conditions. Influent soluble BOD averaged at 55 mg/l, equivalent...

Solubility of Aromat6ic Solutes and Sorption onto Soil in Polar Solvent/Water Systems
An investigation was performed to evaluate the solubility and sorption of aromatic solutes onto soil from an aqueous phase containing polar solvent. This work relates to the evaluation...

Design Approach to Dual-Power Aerated Lagoons
Completely- and partially-suspended lagoon cells are defined and their use in dual-power level, multicellular systems is discussed. A procedure is presented for the design of such systems...

Rotating Biological Contactor System Design
Practical application of Wu's model for the prediction of soluble BOD removal in RBC systems is discussed extensively for various operating conditions. The model was tested by the use...

Cells-In-Series Simulation of Riverine Transport
The transport (advection and dispersion) of a slug of soluble or suspendable material in a river is analyzed by two mathematical descriptions. The models are compared and are applied to...

Simulation of Lime-Soda Softening
A computer model for lime-soda softening has been developed based on the solution of simultaneous chemical equilibrium equations. The effects of ionic strength and temperature on the dissociation...

Parameter Choice for Process Control
Effective real time process control of activated sludge systems subject to transient loadings is dependent upon the identification of sensitive control parameters. Soluble organic concentration...

Aerobic Digestion of Waste Activated Sludge
Activated sludge that had been grown on a completely soluble wastewater in a pilot plant was subjected to aerobic digestion in batch, lab-scale reactors. During the course of digestion,...

Removal of Soluble Secondary-Effluent Organics
Data are presented on the removal of soluble organic nitrogen (SON) and soluble chemical oxygen demand (SCOD) by chemical coagulation, activated-carbon adsorption, ion exchange, lime precipitation,...

Hazardous Wastes Input into Class I Landfills
This study documents 17 metal species discharged to Class I landfill sites. These sites receive a combined estimated daily volume of 2.3 x 106 1/day...

Phosphate Removal Using Waste Calcium Sulfate
Calcium sulfate (gypsum) is a common and inexpensive mineral which is among the cheapest sources of soluble calcium ion available. Relatively pure calcium sulfate is produced as a byproduct...
