Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Bugs and Carbon Make a PACT
At its Chambers Works in southern New Jersey, DuPont was ordered to sharply reduce the BOD load in the wastewater it discharged to the Delaware River. Out of this mandate came the PACT...
Special Water Treatment in New Jersey
The New Jersey Department of Environmental Protection (NJDEP) performed a study on 'special water treatment'. The main goal of the project was to assess in detail...
Removal of EDB from Groundwater by Granular Activated Carbon Filtration
Application of ethylene dibromide (EDB) pesticide to crops may result in contamination of groundwater. Various water treatment alternatives are: granulated activated carbon adsorption,...
What About the Point-of-Use?
Point-of-use (POU) granular activated carbon (GAC) treatment devices are being installed more frequently on community water sytems and on private wells. This article describes carbon filter...
Removal of Radon and Uranium from a water supply
The removal of Radon and Radium from drinking water with the help of granulated activated carbon (GAC) adsorption was investigated. A packed bed column was used for the purpose. It has...
Carbon Columns: Success at Last
The first large scale application of carbon columns for municipal wastewater treatment has been operating for two years. The columns were designed as part of a program to upgrade an out...
Groundwater Models in Choosing Water Treatment Methods
This paper presents an example of the use of groundwater models to identify the source of contamination and then design a treatment scheme. Included is a discussion of several different...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...
Building Assessment Techniques for Indoor Air Quality Evaluations
Techniques for indoor air quality evaluations are presented and discussed. The techniques presented first focus on procedures to determine effective ventilation rates and pathways of air...
The Use of Activated Carbon as a Polishing Step for Treatment of Industrial Plating Wastewaters
An activated carbon adsorption process was utilized as a polishing step following the precipitation (hydroxide or sulfide) process. Zinc and cadmium were the metals studied. Since plating...
Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...
Predicting Carbon Adsorption of Organics from Humid Air
Increased levels of humidity resulted in reduced adsorption capacity for trichloroethylene (TCE) at low influent concentrations on a microporous activated carbon. Water vapor also reduced...
