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...
Estimating Wastewater Capacity of a Cedar Swamp
The response of water table to rainfall provided the basis for estimating the wastewater capacity of a northern Michigan cedar swamp which had been used for disposal of 30 million gallons...
Preliminary Evaluation of Submerged Aquatic Macrophytes in a Pilot-Scale Aquatic Treatment System
A study was done to determine which species of submerged aquatic macrophytes (Elodea nuttallii, Myriophyllum heterophyllum, Ceratophyllum demersum) were suitable candidates for use in...
A Bench-Scale Study of Wastewater Aquaculture Using the Duckweed
A continuous flow bench scale reactor was used to evaluate nutrient removal and growth characteristics of the duckweed, Lemna minor. Such a system can further an understanding of the treatment...
Impact of Dynamic Loading on Bio-Phosphorus Removal
The ability of bench-scale activated sludge biological phosphorus removal systems to produce effluents with consistently low phosphorus concentrations was influenced by influent TOC/COD...
An Innovative Wastewater Management Program
An innovative wastewater management program is described which has been implemented in Orange County, Florida. The wastewater treatment facility utilizes the Bardenpho advanced biological...
Theoretical and Experimental Evaluation of Single-Activated Sludge
The objective of this paper is to discuss the results of operating a laboratory bench scale compartmentalized activated sludge unit operated at a hydraulic detention time ( theta ) of...
Metal Contamination of Sludge by Water Supply Systems
The authors present a cursory review of the source of metals in sewage sludge and an analysis of limited sludge metal data and drinking water data that supports the hypothesis that a water...
Sludge Treatment Design Lands Innovative Funding
The design of sludge treatment facilities for the 10 mgd Ithaca, New York, wastewater treatment plant incorporates both proven technology in the form of gravity thickening and anaerobic...
Transport of Halogenated Organics in Saturated Groundwater Flow: Theoretical and Experimental Results
This paper presents the development of a mathematical model to describe transport of organic chemicals in saturated soil columns and compares model predictions to experimental results....
Solubility of Aromat6ic Solutes and Sorption onto Soil in Polar Solvent/Water Systems
An investigation was performed to evaluate the solubility and sorption of aromatic solutes onto soil from an aqueous phase containing polar solvent. This work relates to the evaluation...
Uncertainty in Unsaturated Zone Pollutant Transport
The portion of a pollutant spill transported to an underlying aquifer is uncertain due to the stochastic nature of precipitation and uncertainty in the geochemical properties of the contaminant...
Design of a GAC Water Treatment System for Radon
The author describes the design of a granular activated carbon (GAC) treatment system for the removal of radon from a public water supply....
Cultivation of Christmas Trees Using Reclaimed Municipal Wastewater
This investigation was initiated to identify benefits and limitations associated with application of reclaimed domestic wastewater to a crop of improved Virginia pine christmas trees....
Water Conserv II - Reclaimed Water for Citrus Irrigation
Water Conserv II is a water reuse project which will involve the use of highly treated wastewater (reclaimed water) for agricultural irrigation. It is anticipated that the project will...
Advanced Filtration Techniques for the Reclamation of Sewage Works Effluent
The central Florida region is currently developing a wastewater reclamation program that will eventually treat 50 MGD (189,300 m**3/d) of municipal wastewater for spray irrigation and...
Innovations in Army Treatment of Remote Site Wastes
The U. S. Army Construction Engineering Research Laboratory (USA-CERL) is currently evaluating new methods for waste treatment at remote sites which will eliminate or mitigate problems...
Analysis of Technologies for Small Water Systems
The problems encountered when small systems must meet the provisions of the National Primary Drinking Water Regulations are discussed. Among the potential water quality problems that could...
Problems in Design of Small Reverse Osmosis Water Purification Systems
Small reverse osmosis water purification systems may be defined as those systems which produce from 100 to 20,000 gallons of water per day. This paper identifies some of the common problem...
A Survey of Anaerobic Digester Operations
In 1981, the ASCE Task Committee on Anaerobic Digestion conducted a survey of wastewater treatment plants throughout the country regarding the use of anaerobic digestion. The two-part...
