An in-depth guide to reverse osmosis desalinationThis Water Environment Federation and WateReuseAssociation publication provides comprehensive information on the planning and engineering of brackish and seawater desalination projects for municipal water supplies. After a brief overview of widely used desalination technologies, Desalination Engineering focuses on reverse osmosis desalination. The book discusses basic principles, planning and environmental review of projects, design and selection of key desalination plant components, desalinated water posttreatment, and concentrate management. Guidelines on sizing and cost estimation of desalination plant facilities are also included in this practical resource. COVERAGE INCLUDES: Source water quality characterization Fundamentals of reverse osmosis desalination Planning considerations Environmental review and permitting Intakes for source water collection Intake pump stations Source water screening and conditioning Sand removal, sedimentation, and dissolved air flotation Pretreatment by granular media filtration Pretreatment by membrane filtration Comparison of granular media and membrane pretreatment Reverse osmosis separation Post-treatment of desalinated water Desalination plant discharge management Desalination project cost estimates

When an oil spill occurs in coastal waters of the United States, responders have several options for managing the environmental impacts of the spill, including the use of chemical dispersants and well containment. Dispersants do not reduce the total amount of oil entering the environment; rather, they help break down oil into small droplets that can more easily mix into the water below the surface, increasing biodegradation rates and potentially decreasing the impact of spilled oil on the shoreline. However, because chemical dispersants promote the movement of oil below the surface, their use exposes the underwater environment and the ocean floor to more of the spilled oil, where it may also have harmful effects. This book examines and assesses new spill response capabiities and technologies, with a focus on dispersants and well containment.

The presence of toxic Cr(VI) in the aquatic environment and their harmful effects on living organisms has emerged as one of the most serious environmental concerns in Thailand, located in the Southeast Asian region. The research, undertaken at the Sirindhorn International Institute of Technology of Thammasat University (2001-2003), directly addressed the need of our society for clean water. This book reports the technical applicability of coconut shell waste, a low cost material from local agricultural waste for treatment of Cr(VI)-contaminated water, and can be a useful resource for environmental scientists, engineers, researchers, policy and decision makers, and engineering students world-wide.

This book describes the solar desalination test plant in Abu Dhabi, UAE and gives a summary of its first year performance and economics. The plant has been operating successfully for 18 years supplying fresh water to the City of Abu Dhabi. The plant was commissioned in September 1984 and was running until the year 2002 when it was dismantled after fulfilling its objectives. The aim of the plant is to investigate the technical and economic feasibility of using solar desalination of seawater in providing fresh water to remote communities in the Middle East and to obtain long-term performance and reliability data on the operation of the plant. The plant has proved its technical feasibility and proved to be reliable in operation with few minor maintenance problems that required slight plant modification. Maintenance routines were established to maintain high plant performance. The economic feasibility of the plant was established by comparing the cost of water from a solar MED plant with a conventional MED plant.

Explore a Viable Resource for Desalination The world's freshwater supplies are rapidly depleting and seawater is being positioned as a major feasible replacement in the search for a sustainable water source. Focused on large-scale multi-stage flash (MSF) seawater desalination plants, and based on research conducted on a real 18-stage plant, Multi-Stage Flash Desalination: Modeling, Simulation and Adaptive Control outlines the principles and processes of MSF desalination and highlights the state of the art in MSF desalination modeling, simulation, and control. This book offers a brief overview of MSF plants, explains the importance of the various control systems for large MSF plants, and describes methods of mathematical modeling centered on physical phenomena in the MSF process. It introduces a developed dynamic model and illustrates the simulation of the model using an equation-based flowsheet simulation package (SPEEDUP) from AspenTech. It also presents a method for finding and using a non-parametric model in designing optimal PID control systems and recommends an adaptive scheme that maintains optimal plant operation over a range of operating conditions. The improvements suggested by the author for PID controllers are pervasive in desalination plants of high dimension and also relate to other process industries with comparable conditions. He also discusses the use of renewable energy sources for desalination and stresses the potential of solar energy in the Arab region, an area known for its aridity and scarcity of water. The text: Details the dynamic model of the various elements in an MSF plant Considers the obtained model as well as available measurement data Presents a developed model for use in PID control Provides descriptions, listings, and additional reference material for further research Multi-Stage Flash Desalination: Modeling, Simulation and Adaptive Control covers the processes of desalination and the operation and control of MSF plants for large-scale desalination and provides you with a greater understanding of dynamics, operation, and control.
