Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...

Using Corps of Engineers' Reservoirs for Water Supply
This paper provides an historical overview of the Corps of Engineers (COE) authority in the water supply arena and discusses the methodologies and procedures used to reallocate storage...

Cranes Roost Lake Level Management Project
An internally drained water body has historically experienced a wide range of lake level elevations due to its function as a regional aquifer recharge area, and due to the urbanized nature...

Iona Outfall Plume Characterization Study
Field studies were conducted in August 1988 to verify the performance of the new deep sea outfall for the Greater Vancouver Regional District (GVRD) Iona Island Sewerage Treatment Plant...

Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
The Brazilian Nuclear Program comprises the Angra I Nuclear Power Plant, in operational tests; the Angra II Nuclear Power Plant, under construction, expected to be completed in 1992; and...

Use of Water Hyacinths to Upgrade Treatment Plants
The primary objective of this research was to evaluate the feasibility of utilizing water hyacinths to upgrade effluents from heavily-loaded municipal wastewater treatment plants located...

A Method for Design and Evaluation of Rapid Sand Filters Treating Secondary Effluents
The information presented in this paper provides a framework for analysis of rapid sand filter performance. Process variables are quantitatively related to filter design variables in a...

Removal of Priority Pollutants in Wastewater by Secondary Treatment and Groundwater Recharge
Monitoring influent and effluent wastewater for organic priority pollutants at two Tucson-area treatment facilities has shown significant removal rates for commonly detected pollutants....

Disinfection Aid?An Innovation in the Chlorination of Wastewaters
A modification to the disinfection process, termed the 'disinfection aid process' for wastewater effluents has been investigated. The addition of a second chemical,...

Application of the ASPEN System for Simulation of the Detroit Waste Water Treatment Plant
The objective of this study is to simulate the Detroit Wastewater Treatment Plant (DWWTP) using the Advanced System for Process Engineering (ASPEN). The primary treatment facility has...

Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...

Long-term Land Treatment: A Performance Evaluation
Overland flow (OLF) land treatment has been applied effectively in the United States for the treatment of industrial and municipal wastewaters. Although several overland flow systems in...

Far-Field Numerical Model Studies for Boston's New Secondary Treatment Plant Outfall Siting
By the late 1900s, Boston is scheduled to have built a new secondary treatment plant that combines the waste streams from two existing plant, and discharges the resulting liquid effluent...

Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...

Ground Water Recharge with Sewage Effluent
Recharge systems for soil-aquifer treatment (SAT) of conventionally treated sewage effluent typically remove essentially all suspended solids, biodegradable material (BOD) and microorganisms...

Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...

A Benthic Environmental Evaluation Protocol for a New Municipal Marine Outfall
Concurrent with siting studies to relocate a 72 mgd secondary outfall diffuser in deep water (200 meters), the Municipality of Metropolitan Seattle initiated a three year baseline study...

Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...

Sewage Trapping by Water Parcels in Puget Sound
Sewage effluent entering Puget Sound, Washington, often becomes trapped in discrete parcels of water. The parcels are easily identifiable in vertical density profiles as layers of well-mixed...

The Benefit of Utilizing Case Specific Modelling and Data to Determine Effluent Limitations
This abstract refers to the results of a normal conservative approach to a more realistic, substantiated approach to determining effluent limitations. The new approach was used to establish...
