Water And Wastewater Management In The Tropics

Water and Wastewater Management in the Tropics provides the necessary conceptual framework and tools to assess all appropriate aspects of water and sanitation projects in developing countries. Using the lessons learned from courses taught at the Technical University of Denmark, Water and Wastewater Management in the Tropics is the concerted effort of a broad team including "hard core" engineers and practitioners as well as "soft core" environmental and institutional planners and economists, with contributions from renowned researchers as well as seasoned project managers. The first part of the book aims to give a basic understanding of international projects and addresses how to identify, formulate, select, organise, cost, finance, implement and manage water and wastewater management projects in developing countries. Later chapters focus on three different types of water and wastewater management projects in a tropical context: rural water and sanitation; urban water and wastewater management; and, industrial water and wastewater management. Water and Wastewater Management in the Tropics will appeal to graduate environmental engineering students but also to practitioners, economists, sociologists, and institutional planners working with water and sanitation projects in developing countries.

This book provides a systematic exposition of the design features of constructed wetlands, and their management (in terms of siting, physical maintenance, and operation). Only very few books (or chapters) have been published on constructed wetlands in tropical conditions and none are current. The selection of plant species, managing their growth and harvesting cycles, and the impact these have on the attenuation of organic and inorganic pollutants, nutrients, and pathogens would be of interest to students and practitioners of the art working under tropical conditions. The potential of constructed wetlands as a low-cost intervention for developing countries in tropical regions that faced water pollution problems, in particular, deserves to be explored systematically.

In warmer climates, sewage loses its content of dissolved oxygen more rapidly, causing it to become "stale" or "septic", necessitating the use of waste stabilization ponds. Waste stabilization ponds utilize environmentally-aware technology in treating the wastewater of communities in hot climates. This book covers waste stabilization ponds in detail, and examines wastewater management and treatment today.

Excess water in the urban environment results in flooding,which causes structural damage, risks to personal safety and disruption to city life. Water is also a major contributory factor for disease transmission as well as being the medium for transport of many pollutants. These problems are of increasing concern due to climate changes and are parti

The IWA Conference on Environmental Biotechnology: Advancement in Water and Wastewater Application in the Tropics, held in Kuala Lumpur, Malaysia on 9-10 December 2003, was a peer-reviewed conference. It was specially organized for Malaysia and the Asia-Pacific region in collaboration between Universiti Teknologi Malaysia (UTM), the International Water Association (IWA), the Malaysia Water Association and the Malaysian Biotechnology Directorate. Papers presented in the conference covered current perspectives on the advancement of water and wastewater applications using environmental biotechnology, as well as methodologies, techniques, modelling, case studies, directions and other specific issues. The emphasis was also on its feasibility in developing countries. The conference also focussed on the biodegradation and bioconversion, health related microorganisms, microbial community structure and analysis, sludge reduction and material recovery, drinking water treatment and safety, nutrient removal and recovery, sensors, modelling and control, molecular techniques, integrated treatment concepts and biological nutrient removal for developing countries, particularly in the tropical region.

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.
