Book Description
Money-saving water strategies for industry.In the U.S. alone, process industries, petrochemicals, pulp and paper, metals and minerals, and many others ù will generate over 120 million tons of wastewater by the year 2000. Industrial Water Reuse and Wastewater Minimization, by James G. Mann and Y.A. Liu, describes water reuse and wastewater minimization principles and practices thatcan be used worldwide. Relatively easy to use and surprisingly inexpensive, the methods youÆll find in this important guide - particularly water-pinch technology ù are not only ecologically sound, but significantly lower manufacturing costs. Concepts are illustrated withabundant charts, tables, and real-life case studies.This resource includes a CD-ROM at no additional cost. Its Water/Target software generates freshwater use/wastewater generation targets, and suggests ways to reach them....lets you isolate bottlenecks limiting water reuse and find new reuse opportunities - all without the expense ofdetailed.

Book Description
Total supply of fresh water on earth far exceeds human demand. However, scarcity of water currently faced in many regions of the world is caused by two reasons. First, its availability in time and space is not equally distributed. Thus there is problem of water in the wrong place, or at the wrong time and in wrong quantities. Second, while the population growth and expanded industrial activities are increasing demands on available water resources, they also jeopardize the availability of freshwater in adequate quantities by discharge of pollutants into freshwater sources. It is at times like these, when the rising curve of water demand intersects the fluctuating curve of water availability, recycle and reuse of wastewater is seriously considered. Wastewater recycling, reuse and reclamation have been, now, accepted as appropriate ways to conserve water resources as well as to contain polluted waters from contaminating other available clean water sources. This book gives a comprehensive review on water quantity and quality, simple water supply and sanitation systems, and leads to domestic, agricultural and industrial water reuse. Thus, it will provide useful information not only to technologists but also for planners, managers, and NGOs involved in the water sector. The contribution to the book comes from a broad pool of experts, working on technology, policy, health, and economy aspects of water management. Involvement of both academics and industry personnel from developing and developed countries makes this contribution broader and useable for a wide readership.

Book Description
This thesis lays out the basic principles for analyzing a water using operation and then compares the freshwater and wastewater flowrates for the system with and without reuse. First, the system is defined as a mass transfer problem in which the contaminant is transferred from a contaminant rich process stream to a water stream. Next, the system is analyzed treating each water-using operation separately. Finally, the minimum freshwater requirement for the integrated system is determined by maximum water reuse subject to constraints such as minimum driving force for mass transfer. For this analysis, the concentration composite curve, the concentration interval diagram and the freshwater pinch are introduced. The methods of regeneration reuse and recycle are also discussed. The approach for single contaminant problem is extended to multiple contaminants problem with multiple constraints. The preliminary mass exchange network is designed on the basis of concentration interval diagram and further simplification is achieved by loop breaking. The basic concepts of each method are formulated into a mathematical code to obtain computer-aided solution to a problem. Two industrial case studies are discussed to illustrate the significance of wastewater minimization and the results obtained are compared with that predicted using analytical method. The first one is a SO2 extraction problem from four process streams and the second is a petroleum refinery complex problem. An average reduction of about 20% in the freshwater requirement is achieved with water reuse while a reduction of about 60 % is achieved by regeneration reuse. There is also a reduction in the number of units in the mass exchange network by four units with water reuse.

Book Description
Water Recycling and Resource Recovery in Industry: Analysis, Technologies and Implementation provides a definitive and in-depth discussion of the current state-of-the-art tools and technologies enabling the industrial recycling and reuse of water and other resources. The book also presents in detail how these technologies can be implemented in order to maximize resource recycling in industrial practice, and to integrate water and resource recycling in ongoing industrial production processes. Special attention is given to non-process engineering aspects such as systems analysis, software tools, health, regulations, life-cycle analysis, economic impact and public participation. Case studies illustrate the huge potential of environmental technology to optimise resource utilisation in industry. The large number of figures, tables and case studies, together with the book's multidisciplinary approach, makes Water Recycling and Resource Recovery in Industry: Analysis, Technologies and Implementation the perfect reference work for academics, professionals and consultants dealing with industrial water resources recovery. Contents Part I: Industrial reuse for environmental protection Part II: System analysis to assist in closing industrial resource cycles Part III: Characterisation of process water quality Part IV: Technological aspects of closing industrial cycles Part V: Examples of closed water cycles in industrial processes Part VI: Resource protection policies in industry

Book Description
Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
