Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...

Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...

The Evaluation of Empty Bed Contact Time on the Biodegradation of Pentachlorophenol using an Anaerobic GAC Fluidized Bed
The objective of this research is to evaluate the effects of decreasing the empty-bed contact time (EBCT) on pentachlorophenol and its intermediates utilizing an anaerobic granular activated...

Development of a Model for the ABF/AS Process
A modelling approach has been established for the activated biofiltration/activated sludge (ABF/AS) process. This approach indicates that ABF/AS systems can be considered as a variation...

Biodegradation of 2,4-Dinitrotoluene in a Two Stage System
An anaerobic/anoxic fluidized-bed GAC bioreactor in series with an activated sludge reactor was used to treat 2,4-Dinitrotoluene (2,4-DNT). A simulated high strength wastewater solution...

Photocatalytic Transformations and Degradation of 2,4,6-trinitrotoluene (TNT) in TiO2 Slurries
The photodegradation of TNT in a TiO₂ slurry reactor was studied as both a potential treatment technique for the remediation of water with munitions...

Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...

Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...

Seismic Effectiveness of Active Tuned Mass Dampers for the Control of Flexible Structures
The possibility of enhancing Tuned Mass Damper (TMP) effectiveness with an added active control capability is presented in this paper. The weighting matrix associated with the components...

Assessment and Prediction of Debris-flow Hazards
Study of debris-flow geomorphology and initiation mechanism has led to better understanding of debris-flow processes. This paper reviews how this understanding is used in current techniques...

Lime Sludge Amended Fly Ash for Utilization as an Engineering Material
Sludges generated from various water treatment operations are predominantly subject to the fate of land disposal. To prepare sludges for land disposal typically requires time consuming...

Exchanging Wastes
For several years, thousands of cubic yards of dried sludge have been stockpiled at the Greater Peoria Sanitary District's wastewater-treatment plant in Peoria, Ill., because...

Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...

Full Scale Application of Active Bracing Systems
A full scale active bracing system has been installed in a structure in Tokyo, Japan. The practical problems associated with the implementation of this system, and the corresponding solutions...

Recent Findings in Active Structural Control
Over the past decade, tremendous advancements have been made in the development of structural control paradigms and in the necessary supporting technologies. The fundamental paradigm that...

Effect of Active Control to Structural Reliability
Most available results in the study of structural reliability deal with idealized mathematical representation of structures. With model supported diagnosis of the structural condition...

Determining Causes for Taste and Odor in Bandar Abbas's Drinking Water
In the south of Iran on the shore of Persian Gulf, Bandar Abbas has a population of over 450,000. The means annual rainfall of Bandar Abbas is less than 205 millimeters of precipitation...

From Sludge to Brokered Biosolids
At the end of June, a sludge filled barge pulled away from New York harbor for the last time. It traveled more than 100 mi offshore, where workers unloaded some of the 355 dry tons of...

Radiation Energy Treatment of Water, Wastewater and Sludge
A State-of-the-Art Report
Since ionizing radiation is one of the more technologically advanced forms of energy available to society, it has been applied to a great many activities such as: the sterilization of...

Gabions and Geogrids
The century-old gabion concept can be improved upon by adding geogrid reinforcement to the soil embankments the gabion wall is designed to support. The grids add stability to the embankment...
