Environmental Effects of Sewage Sludge Disposal


Book Description




Sewage Sludge


Book Description

Sewage sludge is the product resulting from wastewater treatment plants and aquaculture systems. It is an abundant waste biomass, as its production keeps increasing due to population growth, particularly in developing countries and intensified wastewater treatment plants in the developed world due to industrialisation. Effective management and handling of sewage sludge in an environmentally friendly way has become a matter of increasing importance globally, due to the potential health risks on the environment. Importantly, sewage sludge contains large amounts of organic components and nutrients; hence, resource recovery from such an abundant biomass is necessary. This comprehensive book presents an assessment into the impact of sewage sludge on the environment and provides the various treatment options for converting the sludge into useful resources. Biochemical (or biological) and thermochemical (or thermal) methods of sewage sludge treatment are covered. Through contributions from experts in diverse fields, this book has been organised to suit a variety of readers, including professionals and students who are interested in sewage sludge treatment as well as resource recovery from sewage sludge by using different and innovative technologies.

Wastewater Treatment Engineering


Book Description

This book provides useful information about bioremediation, phytoremediation, and mycoremediation of wastewater and some aspects of the chemical wastewater treatment processes, including ion exchange, neutralization, adsorption, and disinfection. Additionally, this book elucidates and illustrates the wastewater treatment plants in terms of plant sizing, plant layout, plant design, and plant location. Cutting-edge topics include wet air oxidation of aqueous wastes, biodegradation of nitroaromatic compounds, biological treatment of sanitary landfill leachate, bacterial strains for the bioremediation of olive mill wastewater, gelation of arabinoxylans from maize wastewater, and modeling wastewater evolution.










Agricultural Recycling of Sewage Sludge and the Environment


Book Description

Sewage sludge application to land is the principal way of deriving a beneficial use for sludge by recycling plant nutrients and organic matter for crop production. It is becoming ever more important as other options for the disposal of sewage sludge are diminishing. Agricultural application also provides a cost-effective method of sludge disposal, but it is essential that sludge recycling in agriculture is regulated to minimize potential environmental problems. This book, based on work funded by the Foundation for Water Research, provides an overview of the environmental impact of sludge application to agricultural land and relates it to other accepted agricultural practices. It puts the potential environmental effects into perspective and distinguishes between perceived and real risk. It is a significant contribution to thinking on this increasingly important topic and is relevant to students and researchers in soil, crop and environmental science. It will also be vital for all those involved in the waste and water industries.
