Measurement of Activated Sludge Rheology
Rheological measurements provide fundamental information on the physical properties of activated sludge. Such properties influence the behavior of activated sludge in wastewater and sludge...
Impoundment Design for Precious Metal Tailings
An engineering study and design of impoundments for the disposal of mill tailings in central Nevada is presented. Mill process waste is generated as flotation tailings and cyanide residue....
Field Scale Solidification/Stabilization of Hazardous Wastes
The selection of appropriate remedial action measures only takes place after a full evaluation of all feasible alternatives. An alternative to off site disposal is solidification/stabilization...
Variable Leachate Treatment System: A Cast Study
This paper explores the experience of the authors in collecting data and designing leachate collection and treatment facilities at municipal sanitary landfills over the last several years....
A Rule-Base Inference System for Liner/Waste Compatibility
Determining the chemical compatibility of a liner material for containment of wastes rests mainly on the application of expert opinion to interpret the results of short-term immersion...
Evaluation of PVC Bottom Linear From an Existing Landfill Located in a Subtropical Climate
Remedial action to curtail leachate seepage on a sanitary landfill located in a subtropical climate included the attachment of new PVC liner to an existing 20 mil PVC liner which has been...
Anaerobic Treatment of Phenol: Degradability, Toxicity and Kinetics
Anaerobic biodegradation of phenol was demonstrated at up to 1000 mg/L in batch serum bottle studies and 1900 mg/L in anaerobic filters. In batch serum bottle studies, concentrations of...
Treatment of the Wastewater From the Alkaline Cooking of Maize in an RBC System
The liquid waste resulting from cooking and washing of maize is called nejayote or nexayote. The soluble COD concentration of this waste ranges from 10,000 to 20,000 mg/l. In an effort...
Land Treatment of API Separator Sludge
An extensive research project was undertaken to establish design and operational guidelines for treatment of oily sludge using land treatment systems. Forty-five test plots were established...
Land Treatment of Refinery Wastes
The authors discuss: waste characteristics; land treatment; and cost comparison with incineration....
Program for Control of Petroleum Refinery Wastewater
The Sanitation Districts of Los Angeles County (LACSD) provide wastewater treatment services to approximately four million residents and eight thousand industrial companies. Large and...
Relating Water Treatment Problems to O & M Factors
The author discusses the operations and maintenance factors that must be considered in dealing with water treatment problems....
Belt Filter Operation and Maintenance Survey (ASCE-WPMC Subcommittee Report)
This report summarizes the results of a national survey of municipal wastewater plant belt press installations conducted by an ASCE Task Committee in 1984. Data from 106 installations...
Lime Sludge Lagoon Dewatering Using a Mobile Belt Filter Press
A major company was faced with the removal of 2100 cubic yards of lime sludge stored in three lagoons. Because the sludge contained relatively high concentrations of tin and nickel, it...
Controlling Factors in Vacuum Filter Performance
Changes in the processes at Milwaukee's Jones Island sewage treatment facilities required testing of the filterability of various mixtures of sludges. The main purpose of...
Design and Construction of TCE/PCE Removal Facilities
This paper presents a review of the design and construction of a facility in Arcadia, California, to remove trichloroethylene (TCE) and tetrachlorethylene (PCE) from ground water. (Edited...
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...
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...
Evaluation of Risks Associated with Dioxin Emissions From a Resource Recovery Facility
Dioxin emissions from resource recovery facilities are a current concern to the application of this technology in the disposal of municipal refuse. A quantitative risk assessment performed...
Hazard Assessment of Landfill Fire Air Emissions
The PJP Landfill, located in northeastern New Jersey, is a suspected hazardous waste site, and is listed on the federal Superfund National Priorities List. In addition to contaminating...
