Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...
Three-Stream Bioprocess Fights Phosphorus in Wastewater Effluent
In-Water Habitat Restoration and Juvenile Salmonid Stranding in the Lower Columbia River
The U.S. Army Corps of Engineers (COE) is considering using an eroded area in the Columbia River estuary to dispose of dredged material from the navigation channel. We conducted baseline...
Establishment of a Habitat Monitoring Program to Assess Potential Impacts of Diversion of POTW Effluent
As part of the permitting process for a gas-fired power plant, the environmental impacts of diverting POTW effluent from the receiving water for cooling tower makeup was investigated....

Effluent Nitrite Accumulation in the Heterotrophic Denitrification of High-Strength Industrial Wastewaters
Non-Traditional Water Quality Approaches
NonPolar Organics Toxicity in a Municipal Effluent
State Permit Program and Toxics Individual Control Strategies: A Case Study
First-Passage Failure Predictions for Yielding Primary-Secondary Systems
Approximate methods are used to investigate the effect of nonnormality (non-Gaussianity) on the time of first-passage failure for a linear secondary system mounted on a yielding primary...
Valuing Residual Emissions in Electricity Planning
Incorporating the valuation of residual emissions into calculations of social cost permits comparisons among alternative sources of electricity generation inclusive of environmental impacts....
Deep Wells Disperse Wastewater Effluent
Wastewater Reclamation and Reuse for Malibu, California
Engineering-Science is providing consulting engineering services for the design of a sewer system and wastewater reclamation plant for the urban portion of Malibu, California. This project...
The Dispersion of Ocean Outfall Plumes: Physical and Biological Dynamics
The discharge of municipal wastewater into the coastal ocean through large ocean outfalls is an important component in managing sewage wastes generated by heavily populated urban areas...
Mixing and Dispersion Processes in the Vicinity of an Ocean Outfall System in Southern California
Ocean wastewater plumes are important for the disposal of municipal wastes in Southern California. These plumes, which are discharged from sanitation systems, can be distinguished in the...
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...
Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...
The Challenge of Meeting New Effluent Guidelines
Meeting new effluent guidelines is presenting a challenge to the environmental engineer. In most cases, existing plants must be retrofitted which will involve options of source treatment,...
UV Disinfection of Wastewater: A Pilot-Scale Study of Performance
A pilot-scale study of UV disinfection under field conditions was conducted. Inactivation and photoreactivation was well correlated with UV dose. Standards of 100 coliform/100 mL were...
Interruption of Sewer Crown Corrosion?Ecological Solutions
