Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. The manual outlines the theoretical …
Many communities are facing water scarcity in developing and developed countries alike. There are numerous publications and on-going research studies documenting the changes in our climate and potential for worsening shortages in our future. Meeting future potable water demands as communities continue to grow will rely heavily on using our existing water resources more efficiently. Preparing…
Over the last decades, some non-OECD countries such as Brazil, Indonesia, Colombia, Mexico, India and China have been rapidly industrializing. While this has had positive effects on economic growth, it has also caused pollution with severe effects . In response to the new pollution threat, most of the industrializing economies have installed pollution prevention and control regulations, and imp…

More than any other locale, the Pacific Ocean has been the meeting place between humans and whales. From Indigenous Pacific peoples who built lives and cosmologies around whales, to Euro-American whalers who descended upon the Pacific during the nineteenth century, and to the new forms of human-cetacean partnerships that have emerged from the late twentieth century, the relationship between the…
The pressure of climate change, environmental degradation, and urbanisation, as well as the widening of socio- economic disparities have rendered the global population increasingly vulnerable to the impact of natural disasters. With a primary focus on medical and public health humanitarian response to disasters, Public Health Humanitarian Responses to Natural Disasters provides a timely critica…
This book aims to provide an overview of how photocatalysis can be employed in water and wastewater treatment. Each chapter will attend to a different area of interest, starting with an introduction on the fundamentals of photocatalysis. The covered topics include metal organic frameworks (MOFs), photocatalytic reactor types and configurations, landfill leachate treatment, and life cycle assess…
Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks t…
The water sector is in the middle of a paradigm shift from focusing on treatment and meeting discharge permit limits to integrated operation that also enables a circular water economy via water reuse, resource recovery, and system level planning and operation. While the sector has gone through different stages of such revolution, from improving energy efficiency to recovering renewable energy a…
This book covers the principles and practices of technologies for the control of pollution originating from organic wastes (e.g. human feces and urine, wastewater, solid wastes, animal manure and agro-industrial wastes) and the recycling of these organic wastes into valuable products such as fertilizer, biofuels, algal and fish protein and irrigated crops. Each recycling technology is described…
