PITTLEACH: A Numerical Model of Landfill Stabilization
This paper addresses the theoretical development, use and application of PITTLEACH, a computer program conceived to simulate the processes of landfill stabilization. Since the physical,...

Optimization Study of a Leachate Treatment System
A treatability study was conducted to evaluate the need for a metal precipitation and an ammonia stripping process in a leachate treatment system and to evaluate the biological nitrification...

Water Plan Deals Carson City a Good Hand?Carson City Revisited
The success of Carson City's new wastewater treatment plant is no surprise. It results from the City's Comprehensive Water Plan (CWP) for ultimate wastewater...

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...

Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....

EPA Guidelines for Water Reuse
The U.S. Environmental Protection Agency and the U.S. Agency for International Development are cosponsoring preparation of water reuse guidelines. The guidelines are being developed to...

Integrated Waste Management at the Weldon Spring, Missouri Site Remedial Action Project
The diversity of contaminants and contaminated media at the Weldon Spring, Missouri CERCLA site, located about 30 miles west of St. Louis, Missouri, necessitates the formulation of integrated...

Land Disposal Restrictions and Mixed Waste Management
The Land Disposal Restrictions, imposed by Congress in 1984 and implemented by the Environmental Protection Agency, impose constraints on the management of mixed waste. Except in very...

Inside the Manhole: New Design on a Leaky Link
Wastewater collection systems represent a major investment for every community, not only in capital dollars, but also in the well-being of community members. Though sanitary sewer manholes...

Planning Subsurface Storage-Transport Facilities for Combined Sewer Overflow Control in Cincinnati, Ohio
The wastewater collection system in the greater Cincinnati area includes a large area served by a combined sewer system. The combined sewer system drains to the Ohio River and several...

Navy Targets Effective Infiltration/Inflow Elimination
The Naval Facilities Engineering Command (NAVFAC), Chesapeake Division, retained the services of RJN Environmental Associates, Inc. to perform a Sanitary Sewer Evaluation Survey (SSES)....

Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...

Toxicity Bioassay Using Nitrifying Bacteria
Monitoring water quality by the use of toxicity bioassay was studied with respect to the interrelationship between nitrifying activities, ammonium and inorganic compounds. Differential...

Toxicity Bio-Assays, 5-Day BOD and Deja Vu
This article revisits some of the basic definitions of toxicity bioassays and 5-day BOD and questions the the precision of these measuements and the long duration of these tests....

Evaluation of In-Situ Bio-Denitrification for Nitrate Reduction in Groundwater
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...

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...

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...

Modifications for Extending the Treatment Capacity
An approach for minimizing influences of increasing raw wastewater flow rates is proposed, based on modifying existing primary sedimentation units, by transforming them to flocculation...

Reuse of an Industrial Wastewater at Saturn
The cooling tower at General Motor's Saturn Plant in Spring Hill, Tennessee will produce blowdown wastewater at rates as high as 500,000 gallons (1893 m3/day)....

Nonpotable Reuse: Development of Water Quality Criteria for Shower Water Recycle
Shower wastewaters at a military installation have been characterized in terms of physical, chemical and microbiological parameters. Two treatment technologies, microfiltration and coagulation...
