An Engineered Reactor Approach to Integrating Physicochemical and Biological Processes for In-Situ Bioremediation of Contaminated Subsurface Systems
The concept of integrating biologically active granular carbon reactors into groundwater recycle schemes to provide continuous acclimation and enrichment of microorganisms and inoculation...

Risk Assessment & Engineered Organisms in Remediation
With the explosive growth of biotechnology, it is likely that bioremediation efforts can be significantly enhanced by employing genetically altered organisms. Before the actual introduction...

Microbiological Stabilization Through Aerobic Digestion and Storage
A study was conducted to evaluate the pathogen indicator bacterial reductions in the sludges of six wastewater treatment plants. These plants were extended aeration and oxidation ditch...

Predicting Microbial Contamination of Ground Water
As a result of the drinking water standards for viruses established by the United States Environmental Protection Agency in 1985, mandatory groundwater disinfection requirements were recently...

The Potential Use of Genetically Engineered Microorganisms in the Remediation of Environmental Pollution
Naturally occurring microorganisms express a broad range of metabolic activities which are being successfully applied to the field of bioremediation. Genetic engineering will enhance such...

Fungal Biodegradation of Lignin-Like Pollutants

The Potential of Indigenous and Added Microorganisms for Degrading Benzene, Toluene and Xylene Under Different Environmental Conditions

Proton Competition in Cu(II) Biosorption by Fungal Mycelia

Microbial Oxidation of Aromatic Hydrocarbon Compounds in Soil-Water Systems

Bottom Plugging Dynamics in Recharge Basins
The Orange County Water District is investigating the reasons why percolation rates in deep recharge basins rapidly decrease. The interrelationship between microbiological activities in...

Efficacy of Membrane Processes for Microbial Control in Drinking Water

Simulation of Multiple Zone Formation in a Uniquely Structured Biofilm Reactor

Biological Treatment of PAHs in Soil Residues in Simulated Land Treatment Systems
The lower molecular weight compounds (2 and 3 ring PAHs) are readily degraded by microorganisms. The heavier molecular weight PAH (polycyclic aromatic hydrocarbon) compounds (4, 5 and...

Modeling of Nitrate Transport Coupled Dentrification in the Saturated Zone
A numerical model for simulating nitrate transport coupled to microbial activity in the saturated zone is presented. A coupled system of equations describes the transport and microbial...

Technical Evaluation of a Copper:Silver Ion Swimming Pool Disinfection Unit
The paper reports on an investigation of a mock swimming pool setup on a laboratory scale. The study used indoor and outdoor simulated swimming pools to compare the efficacy of electrolytically...

Corrosion Monitoring of Critical Service Pipelines
Corrosion, including microbiologically influenced corrosion (MIC), is receiving much attention as a significant piping material performance concern particularly for critical service pipelines...

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...

Effects of Industrial-Municipal Co-Disposal
A study was conducted to evaluate the physical, microbiological, and chemical conditions of nineteen experimental landfills after the completion of a ten-year long municipal refuse/industrial...

Assessment of Analytical Techniques for Monitoring Petroleum Waste Land Treatment Systems
Optimization of wastewater land treatment effectiveness requires current knowledge of the microbiological ecosystem. Environmental parameters must be measured if they are to be adjusted...

Decay in Wood Structures
One of the main causes of wood deterioration is decay. Decay causes millions of dollars in damage to timber structures each year. Left unchecked, decay deterioration can become a structural...
