A Brief History of the Activated Sludge Process Although recorded history and surviving archaeological sites show that the Babylonians and Assyrians, and later the Romans all used quite sophisticated technology to collect and dispose of their wastes, this environmental awareness was not adopted by later ...
In Dallas Fort Worth (DFW), sewage is treated with a combination of anaerobic digestion, effluent filtration and lime stabilization to create biosolids which are then composted, landfilled, or land applied. The current treatment procedure has certain concerns including emissions or accumulation of odors, ...

Selection of appropriate municipal solid waste (MSW) treatment and disposal technology is a complex multi-criteria process. This paper demonstrates the reliability of the use of multi-criteria decision-making (MCDM) framework for the purpose of selecting the best MSW treatment and disposal alternatives. In this ...
In order to delay the degradation of railway tracks, several techniques have been developed in recent years; the best known of which are: under sleeper pads, geogrid and the use of polymers as elastic elements between ballast particles. The objective of the research described in this paper is to evaluate the effectiveness of incorporating tire rubber waste into the ballast layer in reducing its ...
Building on available evidence that there are differences of exposure to solid waste among men, women and children, it follows that effective solid waste management (SWM) policies need to recognise such variations, as a prelude to rolling out programmes to address associated socio-economic and health risks. However, this logical scenario does not seem to be the case in many middle- and low-income ...
Manufacturing wood plastic composites from polyvinyl chloride (PVC) construction waste is one of the options for its continuously increasing scrap utilization. The aim of this study is to estimate the mechanical properties and durability of composites manufactured from recycled and commercially available PVC ...
For purposes of establishing a benchmark against which performance of municipal solid waste (MSW) collection systems can be evaluated by sector regulators, investors and managers, this study assessed the cost efficiency of MSW collection systems in Ghana, using stochastic frontier analysis (SFA). Data from seventy municipal solid waste collection systems were used to estimate the parameters of a ...
The ineffective management of household solid waste (HSW) in most developing cities in Africa including Monrovia has become a major issue threatening the environment and public health. In response to these waste challenges, developed countries have embarked upon major environmental reforms, and have made advances in best practices and sustainable management of their Municipal Solid Waste (MSW). ...
Hydrated products, such as (hydrated) cement pastes, decomposition through physical-chemical alterations when submitted to high temperatures. One of the main factors that lead to microstructural changes during calcination up to 800ºC, is the dehydration phases of hydrated Portland ...
A large proportion of construction waste has a high recovery value, and some of the existing recycling-classification methods rely mainly on physical properties for vibration screening. In order to effectively recover construction waste, an industrial near-infrared hyperspectral camera is proposed in this paper to distinguish the spectral characteristics of the objects. The testing results were ...
As technology and production escalate, the scourge of landfill waste increasingly threatens the environment. This book examines the evapotranspiration (ET) landfill cover, a new and innovative remedy for landfill waste. Offering a solution to conventional landfill, which utilize barriers to the natural flow of ...
This manual of practice – intended to be a source of information for both the inexperienced and the experienced landfillgas system operator – highlights practices and procedures for the operation and maintenance of landfillgas collection and control systems. Overall, provides a deeper understanding of LFG ...
Innovative and Integrated Technologies for the Treatment of Industrial Wastewater deals with advanced technological solutions for the treatment of industrial wastewater such as aerobic granular biomass based systems, advanced oxidation processes integrated with biological treatments, membrane contactors and ...
A NEW SWANA Publication!
