Modeling Ethanol Flushing for NAPL Removal

Two-Dimensional Ethanol Floods of Toluene in Homogeneous, Unconfined Aquifer Media

Comparison of Methods for Sizing Secondary Treatment Filters for Wastewater
The trickling filter process in which a bacterial biomass is allowed to grow attached to a filter medium of rock or plastic is effectively used for removal of organic materials in domestic...

Protecting Drinking Water: Rapid Detection of Human Fecal Contamination, Injured, and Non-Culturable Pathogenic Microbes in Water Systems
The rapid, potentially-automatable extraction of filter retentates has allowed quantitative detection of the unique biomarker for human fecal contamination, coprostanol, and the signature...

Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...

Removal of DNAPL Pools Using Upward Gradient Ethanol Floods

Management of High-Rate Trickle Bed Biofilters

Here Comes the Sun
This article is an overview of recent developments in alternative and renewable energy technologies. The entire field is reviewed and four energy sources likely to impact short-term markets...

Analysis of Biomass Distribution and Chemical Interactions in Nitrifying Biofilms
Steady-state models of nitrifying biofilms are developed taking into account the mass transfer of neutral and ionic species, electroneutrality, pH-dependent Monod kinetics, chemical equilibrium,...

A Preliminary Evaluation of Transport Mechanisms for Multiple Substrates in a Laboratory Column System

Environmental Impact of a Power Plant: A Case From a Coastal Area in Venezuela
These are the results of a eight years study in which the ecological effects of Planta Centro power plant were assessed. Many aspects were included in this study, but we concentrate here...

Integrated Management of Sugarcane Mill Wastewater for Bioenergy Production and Drip Irrigation
Based on the previous work of wastewater characterization and relevant literature review, a combined anaerobic (UASB) and aerobic (EAFB) treatment of supernatant of settled sugarcane mill...

Aerobic Denitrification in Activated Sludge
Definitive proof of the phenomenon of concurrent biological nitrification-denitrification in activated sludge is presented. The mechanism appears to be an inhibition of oxygen respiration...

Biological Methods for Air Decontamination: Modeling Hydrocarbon Removal
Bench-scale tests indicate biofilter treatment of gasoline and diesel with activated carbon support media is first order, while removal of ethanol on compost is zero order. Treatment of...

Degradation of 1-Naphthylamine by Activated Sludge Using Bioaugmentation
This paper presents the results of ongoing research using a novel bioaugmentation scheme for activated sludge (AS) treatment of trace levels of a hazardous compound (1-Naphthylamine, 1NA)....

Instream Flow Needs Below Peaking Hydroelectric Projects
A method has been developed to assist in the determination of instream flow needs below hydroelectric projects operated in a peaking mode. Peaking hydroelectric projects significantly...
