A Value Chain Model to Support Business Process Reengineering in Turnkey Contracting Firm
This paper discusses important factors of BPR as it is related to the use of information technology in the E&C industry. It then presents an industry value chain model from the...
Computer Use in Claims Analysis -- Roundtable Discussion
Preparation or defense of construction claims is inherently time consuming and often counter-productive. This outline discusses some tools currently used in the construction industry to...
Settlement Evaluation for Cap Closure Performance
Predicting short and long-term performance of a landfill cap system is a difficult task considering the generally unknown nature of the waste and magnitude and variation of settlement...
Modeling Settlements of an Existing Municipal Solid Waste Landfill Sideslope Using an Earthen Surcharge Pile
This paper discusses the results of a large-scale field compressibility test completed on municipal solid waste (MSW). The test consisted of surcharging the waste mass with an earthen...
The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...
Meeting 503 Regulations for Ten Biosolids Incinerators (And Associated Stories)
This paper provides an overview of the Hampton Roads Sanitation District's Part 503 regulations compliance program regarding incineration of biosolids at five of its treatment facilities....
Beneficial Use Alternatives for Water Treatment Plant Residuals
The beneficial use alternatives which are currently in practice for water treatment plant residuals and their relative advantages and disadvantages are summarized in this paper. The alternatives...
Beneficial Use of Ash: An Innovative Approach to Sludge Management
Disposal of ash resulting from the incineration of municipal sewage sludge has historically been a relatively easy, albeit, expensive requirement. The traditional method of disposal is...
Modifying One of the Nation's Most Successful Biosolids Lime Stabilization Operations
Since 1978, the Vallejo, California, Sanitation and Flood Control District has managed a tremendously successful biosolids program consisting of lime stabilization and agricultural land...
Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...
Optimizing Secondary Clarifier Performance: A Presentation Outline
Optimizing secondary clarifier performance is an activity that involves a consideration of the design, the maintenance, and the operation of the clarifier. Although the basic shape of...
Evaluating Activated Sludge Secondary Clarifier Performance: A Protocol
To establish a consistent methodology for evaluating secondary clarifier performance, the ASCE Clarifier Research Technical Committee prepared procedural guidelines in the form of a draft...
Sludge Hopper Design for Activated Sludge Clarifiers
Only in the past few years has any attention been allocated to the transport characteristics of sludge collectors. However, no attention has been given to a design rationale for the sludge...
Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...
Chelating Composite Membrane: Its Application in Selective Heavy-Metal Solid-Phase Separation
Selective removal of small amounts of heavy metals from the background of large amounts of innocuous sludge or slurry is a challenging separation problem. Conventional fixed-bed sorption...
