Choosing Ecological Sewage Treatment


Book Description

Choosing Ecological Sewage Treatment describes several off-mains sewage treatment systems and shows you how to deal safely with the sewage of up to about 50 people. - Understand nutrient recycling and the 'big circle' of sewage. - Find out which system is right for your situation: includes reed beds, septic tanks, cesspools and leach fields. - Learn how to separate, collect and use urine and the water from your kitchen and bathroom. - Become water wise and cut down on waste. Experienced practitioners Grant, Moodie and Weedon give a thorough tour of the subject, provide the most up-to-date advice regarding sewage regulations and illustrate their subject with case studies of systems they have installed themselves.

"This manual contains overview information on treatment technologies, installation practices, and past performance."--Introduction.




The Ecology of Waste Water Treatment


Book Description

« The Ecology of Waste Water Treatment covers the principles of biology considered necessary for an understanding of some ecological aspects of wastewater treatment. This book is composed of seven chapters, and begins with an overview of the significant biological aspects related to wastewater treatment. The subsequent chapters examine the factors determining the dominant organisms in sludge and bacteria beds. Other chapters highlight the role of biological oxidation in wastewater treatment and the ecological parameters in the design and operation of activated sludge plants. A chapter provides practical methods of maintaining population balance at a low level of microorganisms. The final chapter considers the operational requirements necessary to ensure suitable ecological conditions for bacteria beds. This book is of value to microbiologists, ecologists, and environment-related fields. » --




Choosing Environmental Policy


Book Description

The two distinct approaches to environmental policy include direct regulation-sometimes called 'command and control' policies-and regulation by economic, or market-based incentives. This book is the first to compare the costs and outcomes of these approaches by examining realworld applications. In a unique format, paired case studies from the United States and Europe contrast direct regulation on one side of the Atlantic with an incentivebased policy on the other. For example, Germany‘s direct regulation of SO2 emissions is compared with an incentive approach in the U.S. Direct regulation of water pollution via the U.S. Clean Water Act is contrasted with Hollands incentive-based fee system. Additional studies contrast solutions for eliminating leaded gasoline and reducing nitrogen oxide emissions, CFCs, and chlorinated solvents. The cases presented in Choosing Environmental Policy were selected to allow the sharpest, most direct comparisons of direct regulation and incentive-based strategies. In practice, environmental policy is often a mix of both types of instruments. This innovative investigation will interest scholars, students, and policymakers who want more precise information as to what kind of 'blend' will yield the most effective policy. Are incentive instruments more efficient than regulatory ones? Do regulatory policies necessarily have higher administrative costs? Are incentive policies more difficult to monitor? Are firms more likely to oppose market-based instruments or traditional regulation? These are some of the important questions the authors address, often with surprising results.




Design and Selection of Small Wastewater Treatment Systems


Book Description

This report provides general information on the design and selection of wastewater systems with capacities for populations up to 2500. This information is intended for use by individuals with limited experience in wastewater treatment and disposal as a source of available alternatives in small systems, as well as an outline of the steps and procedures to undertake when selecting a particular wastewater management scheme for a small community. Material covered includes: measurement and estimation of wastewater flows; physical, chemical and biological characteristics of domestic wastewater; on-site wastewater treatment and disposal processes; central wastewater collection and treatment systems; operating problems associated with small treatment systems; disposal of liquid effluents and waste sludges; and procedures employed in the selection and approval of wastewater systems. A case history is provided to illustrate the selection procedures discussed within the text.







Nature Based Solutions for Wastewater Treatment


Book Description

There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential to be further promoted globally as both a sustainable and practical solution. This book serves as a compilation of technical references, case examples and guidance for applying nature-based solutions for treatment of domestic wastewater, and enables a wide variety of stakeholders to understand the design parameters, removal efficiencies, costs, co-benefits for both people and nature and trade-offs for consideration in their local context. Examples through case studies are from across the globe and provide practical insights into the variety of potentially applicable solutions.




Sewage Treatment Plants


Book Description

Sewage Treatment Plants: Economic Evaluation of Innovative Technologies for Energy Efficiency aims to show how cost saving can be achieved in sewage treatment plants through implementation of novel, energy efficient technologies or modification of the conventional, energy demanding treatment facilities towards the concept of energy streamlining. The book brings together knowledge from Engineering, Economics, Utility Management and Practice and helps to provide a better understanding of the real economic value with methodologies and practices about innovative energy technologies and policies in sewage treatment plants.
