Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti

Reports

Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Social, Economic, Environmental, And Technical Factors Influencing Water Reuse, A. Bruce Bishop, Suravuth Pratishthananda, John Keith, Craig Colton, A. Berry Crawford

Reports

A growing population together with rising per capita income has resulted in increased demand for water for virtually all uses. At the same time there has been increased public concern for maintaining the quality of streams for recreation, sight-seeing, and other social uses, and to conserve environmental values. A partial answer to these conflicts in water use and management is more extensive waste water reclamation and reuse. Heretofore, water salvage and reuse has been mainly practiced in specific operational cases, such as recycling industrial process water, or on an ad hoc basis, such as a series of diversions and subsequent …

Sorption Kinetics Part Ii: Modeling Longitudinal Concentration Profiles In A Packed Bed Reactor, David W. Hendricks

Reports

A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates …

Chronic Effect Of Low Ph On Fathead Minnow Survival, Growth And Reproduction, Donald I. Mount

United States Environmental Protection Agency: Publications

Fathead minnows (Pimephales promelas Rafinesque) were continuously exposed to reduced pH levels of 4.5, 5.2, 5.9, 6.6 and 7.5 (control) during a 13-month, one-generation test. Survival was not affected, even at the lowest pH tested. Fish behavior was abnormal, and fish were deformed at pH 4.5 and 5.2. Egg production and egg hatchability were reduced at pH 5.9 and lower, and all eggs were abnormal. A pH of 6.6 was marginal for vital life functions, but safe for continuous exposure. Free carbon dioxide, liberated by the addition of sulfuric acid to reduce the pH, may have had an unknown …

An Evaluation Of Water Softening, James Burr Aton

Retrospective Theses and Dissertations

Dynamic modeling is proposed in this paper as a method of developing a computer model to simulate a water softening treatment unit. Information on water softening economics and ion exchange are examined. The development of a dynamic model is oriented toward uniform effluent water quality and operational flexibility. Several methods are presented to determine the reaction rate used in the completely mixed flow reactor's dynamic model.

Interior Noise In Military Helicopters, Charles E. Perez Jr.

Masters Theses

"The Temporary Threshold Shift (TTS) or temporary hearing loss caused by excessive interior noise in military helicopters results in a critical degradation of the acoustically unprotected infantryman's ability to detect the existence or the approach of the enemy by hearing under combat conditions. The overall problem of noise reduction in helicopters consists of: (1) identifying the various noise sources, and (2) employing appropriate noise control techniques. Identification of the source is accomplished by the frequency correlation of 1/10-octave band analysis of the interior sound levels measured within the helicopter cabin with near-field sound generated by the sound sources. Reduction of …
