Beneficial Use of Municipal Sewage in the Ocean
When sewage sludges and effluents are introduced in a properly controlled manner, they can be of benefit to large areas of the ocean. For example, benthic biomass and growth rates of commercially-valuable...

Waste Cleanup: Lessons Learned
Since hazardous waste mitigation is a new science, engineers need to pass on their experiences. The U. S. Army Waterways Experiment Station, seeking to expand the hazardous waste knowledge...

Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...

Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...

Overview of EPRI'S Solid Waste Environmental Studies
The Electric Power Research Institute (EPRI) initiated a comprehensive research project in 1983 with the long-term goal of improving and validating methods for predicting the fate of chemicals...

Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters
The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other...

Lessons Learned from First Impulse Turbine Installation in the U.S. Mining Industry
The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining...

Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...

Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...

Hydrothermal Model Study of Stratified Flow in a Power Plant Cooling Water Recycle/Intake Canal: Reynolds and Densimetric Froude Number Effects
During the winter of 1983-1984, the control of frazil ice at the trash tracks using pneumatic air guns was evaluated at Danskammer Point Generating Station. This paper presents a brief...

Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...

Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...

Biofouling Control of Water Intake Structures
Biofouling of water intakes can affect condenser performance and availability. This paper discusses four biofouling control technologies: thermal backwash, antifouling coatings, chlorination,...

Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...

Series Finished Water Pumping Facilities
The paper discusses studies and design of series finished water pumping facilities for the Potomac River Water Treatment Facilities. Detailed hydraulic studies were conducted which concluded...

Analysis of Resonance in Pressurized Piping Systems Via a Microcomputer
In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method...

Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...

Small Water Users�Planning Crisis
Planning to rehabilitate small water systems�both irrigation and municipal water supply�often is ignored. In contrast, planning for new construction and for operations/maintenance work...

Private Funds, Public Projects
Tapping private sources for public services is not new, though the concept has advanced from traditional contracting for services, which has been around since pre-Revolutionary War days....

Environmental Engineering
The purpose of the annual Conference on environmental engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of environmental...
