This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk parlor wastewater in a dairy operation in Hawaii was investigated for its potential treatment and reuse. Two earthen settling ponds were served as settling process and another 10 acres of wetland were planted with California grass to receive the effluent from settling ponds. It was found that the present treatment systems still remained many problems, such as odor, potential groundwater contamination and surface water pollution. The effluent could not meet the requirements for either disposal or reuse. Improving and integrating other cost effective biological treatment component(s) to the existing lagoons is required in order to meet discharge or reuse standards. Several biological treatment technologies were evaluated and investigated as the alternatives. In order to improve these existed problems, a 5-S approach (system existed, short HRT, small investment, simple operation and maintenance, system thinking) is developed. Among the 5-S, development of a higher SRT (Solids Retention Time) for the bioreactor is essential in order to integrate this unit into the other 4-S.A bioreactor, which is the modification of UASB (Upflow Anaerobic Sludge Blanket) reactor, was investigated. It was found that more than 70-75% of TCOD (Total Chemical Oxygen Demand) removal efficiency and biogas production of 1.5l/l/day with CH4 content of 70-75% could be achieved at 8-15g COD/l/day. The unique operation of the developed bio-nest reactor is able to achieve a higher COD removal efficiency with high organic loading rate with simple design and operation. This unique bioreactor is able to provide better sludge distribution and less dead zone compared to the conventional UASB. The process performance, design and operation criteria of this bioreactor were presented, discussed and compared with the existing anaerobic filter reactor and UASB reactor for the treatment of milk parlor wastewater. It was found that this bioreactor is able to operate in the temperature of 22" 2°C compared.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.
