Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...

Evaluation and Selection of RBC Models for Design of Domestic Wastewater Facilities
This study evaluated three existing models commonly used for the design of Rotating Biological Contactors (RBC). Operating data from six RBC Treatment Plants located in eastern Massachusetts...

Composting Works for Small Wastewater Treatment Plants
The City of Cooper City, Florida, faced with the undesirable position of relying on outside contractors for sludge disposal needs, undertook the task of developing a self-sufficient sludge...

Aerobic Thermophilic Digestion or Liquid Composting of Municipal Sludges
A study funded by Supply and Services Canada through the Wastewater Technology Center of Environment Canada, and the Province of British Columbia is being undertaken over a two year period...

Experimental Study of Windrow Composting of Sludge
An experimental field study of the windrow composition of sludge at the City of Dallas, Texas, Southside Waste Water Treatment Plant was conducted to provide data for possible design of...

Design of Solidified/Stabilized Sludge Landfills
Rehabilitation of highly moist, compressible, and heavy metal-containing wastewater treatment sludges for final disposal in a landfill setting requires consideration of several factors....

Simulation of Oxygen Dynamics in the Vadose Zone
A microcomputer model VIP (Vadose Zone Interactive Processes) was developed as an extension of the RITZ model to provide a mathematical description of land treatment systems for the disposal...

NAPL and Contaminant Transport in the Soil Matrix
A one-dimensional multiphase mass transport model for the migration of a Non-Aqueous Phase Liquid (NAPL) containing sparingly water soluble organics in the unsaturated soil zone is described....

Fate and Transport of an Acid Waste in Soil and Groundwater
A fate and transport study at a closed acid waste pond located on the shore of San Francisco Bay indicated the potential of native soil and groundwater for retarding the movement of contaminants...

Effect of Concentration on the Biological Degradation of Petroleum Hydrocarbons Associated with In Situ Soil-Water Treatment
Sandy soil samples contaminated with weathered JP-5 jet fuel were mixed with uncontaminated sand to provide a concentration gradient from 187 to 1565 mg total petroleum hydrocarbons (TPH)/Kg...

Biological Treatment of PAHs in Soil Residues in Simulated Land Treatment Systems
The lower molecular weight compounds (2 and 3 ring PAHs) are readily degraded by microorganisms. The heavier molecular weight PAH (polycyclic aromatic hydrocarbon) compounds (4, 5 and...

Aerobic Biodegradation of Chlorinated Solvents in Unsaturated Soils
A potentially attractive application of methylotrophic bacteria is in the treatment of contaminated, unsaturated soil. Methane and air could be supplied by injection and withdraw wells,...

Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...

Mathematical Modeling of Compressible Cake Filtration
A numerical and analytical model of cake filtration was derived from liquid and solid continuity and momentum equations. Constitutive relationships describing porosity as functions of...

Environmental Analysis of Sludge Disposal Options
In a Court-ordered agreement to eliminate disposal of sludge from its treatment plants into the ocean, the City of Los Angeles was required to evaluate alternatives for transporting and...

Water Oxidation of Sludges and Toxic Wastes
Waste treatment technologies such as subcritical and supercritical water oxidation processes offer innovative alternatives to vexing sludge and toxic wastewater treatment problems. This...

Digester Gas Resource Recovery at Phoenix, Arizona
Until July 1986, the digester gas produced at this 150 million gallon per day facility, in excess of what was utilized for heating anaerobic digesters was flared. In 1983, a feasibility...

Stabilization of Critical Enclosed Natural Draft Ground Flares
This paper presents the results of an investigation evaluating the causes of and implementing a cost effective solution to combustion driven oscillations in six large natural draft flares....

Conversion of Mixed Waste to LSA Waste?A Case Study
This paper describes a treatment process that was successfully employed at the National Guard Armory in Chicago, Illinois, to convert sludge classified as hazardous chemical/radioactive...

Radioactive Mixed Waste at the Waste Isolation Pilot Plant
This paper discusses compliance by the U.S. Department of Energy Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico with the Resource Conservation and Recovery Act (RCRA) (1)....
