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.

Water Renovation and Reuse focuses on the general principles and technological developments of water reuse and renovation. This book provides documented case studies of reuse practices and experiences throughout the world. Organized into two parts encompassing 15 chapters, this book starts with an overview of the different aspects of the problem to conserve, reuse, and recycle the limited water resources. This text proceeds to discuss the initial phase of water renovation and reuse, which is based on the conservationists' concept that society's wastes should be utilized and conserved to preserve the fertility of the soil. Other chapters explore the second phase of water renovation and reuse, which is motivated by the need to conserve and reuse water in arid areas. This book discusses as well the policy of zero pollution in the United States, which led to programs of land disposal. This book is intended for biologists, engineers, chemists, agronomists, public health officers, and water resources authorities.

Over the past half century, reverse osmosis (RO) has grown from a nascent niche technology into the most versatile and effective desalination and advanced water treatment technology available. However, there remain certain challenges for improving the cost-effectiveness and sustainability of RO desalination plants in various applications. In low-pressure RO applications, both capital (CAPEX) and operating (OPEX) costs are largely influenced by product water recovery, which is typically limited by mineral scale formation. In seawater applications, recovery tends to be limited by the salinity limits on brine discharge and cost is dominated by energy demand. The combination of water scarcity and sustainability imperatives, in many locations, is driving system designs towards minimal and zero liquid discharge (M/ZLD) for inland brackish water, municipal and industrial wastewaters, and even seawater desalination. Herein, we review the basic principles of RO processes, the state-of-the-art for RO membranes, modules and system designs as well as methods for concentrating and treating brines to achieve MLD/ZLD, resource recovery and renewable energy powered desalination systems. Throughout, we provide examples of installations employing conventional and some novel approaches towards high recovery RO in a range of applications from brackish groundwater desalination to oil and gas produced water treatment and seawater desalination.

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.

The effective integration of water and reclaimed wastewater still requires close examination of public health issues, infrastructure and facilities planning, wastewater treatment plant siting, treatment process reliability, economic and financial analyses, and water utility management. This book assembles, analyzes, and reviews the various aspects of wastewater reclamation, recycling, and reuse in most parts of the world. It considers the effective integration of water and reclaimed wastewater, public health issues, infrastructure and facilities planning, waste-water treatment plant siting, treatment process reliability, economic and financial analysis, and water utility management.
