Overview

Recently, research efforts aiming to improve energy efficiency of wastewater treatment processes for large centralized wastewater treatment plants (WWTPs) have been increasing. Global warming impacts, energy sustainability, and biosolids generation are among several key drivers towards the establishment of energy-efficient WWTPs. WWTPs have been recognized as major contributors of greenhouse gas emissions as these are significant energy consumers in the industrialized world. The quantity of biosolids or excess waste activated sludge produced by WWTP will increase in the future due to population growth and this pose environmental concerns and solid waste disposal issues. Due to limited capacity of landfill sites, more stringent environmental legislation, and air pollution from incineration sites, there is a need to rethink the conventional way of dealing with wastewater and the sludge production that comes with it. This book provides an overview of advanced biological, physical and chemical treatment with the aim of reducing the volume of sewage sludge. Provides a comprehensive list of processes aiming at reducing the volume of sewage sludge and increasing biogas production from waste activated sludge. Includes clear process flowsheet showing how the process is modified compared to the conventional waste activated sludge process. Provides current technologies applied on full scale plant as well as methods still under investigation at laboratory scale. Offers data from pilot scale experience of these processes

Author Information

Dr. Antoine Trzcinski received his PhD from the chemical engineering Department of Imperial College London in the United Kingdom. He developed a novel process for producing biogas from municipal solid waste and for the treatment of landfill leachate. As a senior Research fellow in the Nanyang Environment & Water Research Institute he continued working on solid waste treatment such as waste activated sludge and wastewater treatment in anaerobic membrane bioreactors. He developed novel combinations of pre-treatments of waste activated sludge that result in greater biogas production. He was granted three patents from this work in collaboration with the Public Utilities Board of Singapore. His research interests include fouling mitigation in membrane bioreactors, characterization of soluble microbial products, identification of bacterial and archaeal strains, pharmaceutical and antibiotics removal from wastewater, fate of nanoparticles in the environment and bioelectro stimulation of microbes to improve bioprocesses through interspecies electron transfer (IET). In 2016, He joined the University of Southern Queensland as lecturer and teaches Environmental engineering, Environmental Engineering Practice, Hydraulics, Solid and Liquid Waste Treatment and Applied Chemistry and Microbiology as well as continuing his research in these fields.
