Who is Taking Out the Garbage?
Due to the shortage of landfill space and the increasing amount of waste being generated, current waste disposal techniques should be studied and revised. New methods should be implemented...
Numerous releases of hazardous substances have occurred at uncontrolled sites all around the United States. These sites pose toxic threats to public health and our environment, and potential...
Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...
Noise Control Program for the Boston Harbor Project
A noise control engineering program has been instituted for the Boston Harbor project to make the facility virtually inaudible at the property line. The program integrates the noise mitigation...
Environmental Protection, Resource Allocation and CERCLA: A Practitioners Perspective
In accepting Superfund's mandate of protection of human health and the environment in a timely manner, critics often overlook, the limited human, technical and material resources...
The Effects of Hazardous Organic Pollutants on the Performance of Activated Sludge Systems
The effects of phthalate esters (diethyl phthalate and dimethyl phthalate) and phenols (2,4-dinitrophenol, 2,4-dimethylphenol and 4-nitrophenol) on the performance of a laboratory-scale...
Vacuum Anaerobic Treatment: A New Approach
Anaerobic processes have an organic loading limit that when exceeded leads to process failure. The research summarized in this paper demonstrates that both organic removal rate enhancement...
Influence of Hydrodynamics on Biofilm Accumulation
The influence of hydrodynamics on biofilm thickness was investigated under laminar and turbulent flow conditions. The maximum biofilm thickness was found within the transition region between...
Optimization of Innovative Biological Treatment
This paper presents the experimental and theoretical development of a method for predicting the optimal operating conditions for an innovative biological reactor design. The innovative...
Protecting a Sensitive Ecosystem Through Advanced Treatment at the Reno-Sparks Wastewater Treatment Facility
The requirements for high degrees of nutrient removal at the Reno-Sparks Wastewater Treatment Facility required employment of several cost-effective, innovative treatment process applications....
Products of Chloramination in Dilute Aqueous Solution
Chloride and nitrate formation was determined in the reaction of chlorine with ammonia in molar excess, in dilute aqueous solution. Nitrate was formed under all conditions investigated....
