A comprehensive guide to sludge management, reuse, and
disposal
When wastewater is treated, reducing organic material to carbon
dioxide, water, and bacterial cells–the cells are disposed of,
producing a semisolid and nutrient-rich byproduct called sludge.
The expansion in global population and industrial activity has
turned the production of excess sludge into an international
environmental challenge, with the ultimate disposal of excess
sludge now one of the most expensive problems faced by wastewater
facilities.
Written by two leading environmental engineers, Biological
Sludge Minimization and Biomaterials/Bioenergy Recovery
Technologies offers a comprehensive look at cutting-edge
techniques for reducing sludge production, converting sludge into a
value-added material, recovering useful resources from sludge, and
sludge incineration. Reflecting the impact of new stringent
environmental legislation, this book offers a frank appraisal of
how sludge can be realistically managed, covering key concerns and
the latest tools:
* Fundamentals of biological processes for wastewater treatment,
wastewater microbiology, and microbial metabolism, essential to
understanding how sludge is produced
* Prediction of primary sludge and waste-activated sludge
production, among the chief design and operational challenges of a
wastewater treatment plant
* Technologies for sludge reduction, with a focus on reducing
microbial growth yield as well as enhancing sludge
disintegration
* The use of anerobic digestion of sewage sludge for biogas
recovery, in terms of process fundamentals, design, and
operation
* The use of the microbial fuel cell (MFC) system for the
sustainable treatment of organic wastes and electrical energy
recovery
