Adsorption Technology for Mercury Control in Flue Gases

Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...

Detailed Characterization and Preliminary Adsorption Model for Materials for an Intermediate-Scale Reactive-Transport Experiment

Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...

Treatment of Oil in Water Emulsions by Ceramic-Supported Polymeric Membranes
A novel membrane was developed by growing polymer chains from the surface of a porous ceramic support, resulting in a composite membrane which combines the mechanical properties of the...

Control of Odor and VOC Emissions at Wastewater Treatment Plants -Boston Harbor Case Study-
Siting of the new wastewater treatment plant (WWTP) for the Massachusetts Water Resources Authority (MWRA) in Boston was based on an assumption of mitigation of total reduced sulfur (TRS)...

Process Selection for Treatment of SOC Contaminated Waters
The most inexpensive method for treating synthetic organic chemical (SOC) contaminated wastewaters was studied. Air stripping, liquid-phase adsorption, fixed-film biological oxidation,...

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...

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...

Effects of Core Sealing Methods on the Preservation of Pore Water
Five general core sealing methods (using Protecore, Lexan, wax, Protecore with wax, and Protecore with Lexan) were studied over a two year period to determine their moisture retention...

Modeling Adsorption of Mixtures of Radionuclides by Zeolitized Tuff
Multi-solute sorption isotherms were measured using 'nonscents', a zeolitized volcanic tuff material from Southeast Arizona. Isotherms for the three constituent binaries, Sr-Co, Cs-Sr...

In-Flight Calibration of Mass Spectrometer
A new device for in-flight calibration of mass spectrometer is presented. At a ground station command the calibrator introduces a constant and reproducible amount of deuterium into the...

A Preliminary Evaluation of the Adsorption of Lindane, Silvex and 2,4-D in Single and Multicomponent Systems onto Whole Soil and Soil Organic Fractions

Improved Performance of Activated Sludge with Addition of Inorganic Solids

Atrazine Biodegradation in Biological GAC Columns

Aquifer Restoration: Which Method?
Ground-water contamination is an increasing problem, especially in large urban areas. Toxics that seep into water supplies threaten the health of the community and it's difficult...

Adsorption of Lindane onto Whole Soil and Soil Organic Fractions
The work presented here investigated interactions of the subject pesticide with whole soil and select soil organic fractions and evaluated the commonly applied assumptions that adsorption...

Separation of Organics from the Aqueous Phase Using Polymeric Resins
The adsorption of tetrachloroethene (PCE) onto several polymeric materials is reported and compared to activated carbon F-400. In addition, the bisolute adsorption of chloroform and trichloroethene...

Development of a Sorbent for Removal of Nonionic Pollutants from Water
Sorption of anionic surfactants onto mineral oxides and, and the subsequent partitioning of non-ionic organic substance into the organic phase of these synthetic sorbents was studied....
