The design of water supply systems based on desalination
United Nations. Dept. of Economic and Social Affairs.
Water systems maintain more than 2 million miles of distribution mains. 11 In , nearly 80% of systems were less than 40 years old, while 4% were more than 80 years old. 12 , main breaks occur each year in the US, disrupting supply and risking contamination of drinking water. The drinking water filtration systems offer constant and reliable operation, which however requires high degree of automation, reliable power supply and relatively high costs. There are also gravity driven systems on the market and in development, more suitable for remote applications.
Early applications of desalination were small-scale plants deploying a range of technologies. However with the technological developments in Reverse Osmosis, most new plants use this technology because it has a proven history of use and low energy and capital costs compared with other available desalination technologies. This has led to the recent trend for larger seawater. The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Major human settlements could initially develop only where fresh surface water was plentiful, such as near.
Executive Summary 5 Reuse/Recycling Aside from the desalination of seawater or brackish aquifers, one potential solution to the nationâ s water supply problem is to utilize increasingly impaired waters, such as municipal wastewaters, by applying desalination treatment technologies for contaminant removal. Reverse Osmosis Desalination Process. The core process of desalination is the Reverse Osmosis Process. It consists of a High pressure pump followed by an Energy Recovery device and the Reverse Osmosis Membranes. SWRO. High pressure pump. Before entering the seawater reverse osmosis membranes, clarified seawater is pressurized by the High Pressure Pump typically between 55 and 85 .

Ideally, these considerations should be compared against equally rig- orous environmental impact analyses of water supply alternatives, so that decisions can be made based on comparisons of the full economic costs and benefits, including environmental and social costs and benefits, among the various.
The socio-economical development of many regions lacking a sufficient supply of fresh water (FW) may at times be planned with the help of desalination technologies for sea and brackish water (SW.
This chapter discusses the cost of desalination powered by % renewable energy power plants and demonstrates how and why renewable energy powered desalination is a lucrative option to meet the future global water demand.
The global desalination demand bybased solely on water stress and water demand, is estimated. Saltwater is desalinated to produce water suitable for human consumption or by-product of the desalination process is brine.
Desalination is used on many seagoing ships and of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water sources.
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/5(17).
Rational Design of Next-generation Nanomaterials and Nanodevices for Water Applications is intended for undergraduates, graduates, scientists and professionals in the fields of environmental science and engineering, material science, chemistry, and chemistry engineering.

Water production and transfer are the main energy consumers in a desalination-based water supply system. The average specific energy consumption of 4 kWh/m 3 was considered for all desali- nation.
Desalination produces fresh water from seawater. Given that seawater accounts for 97% of water on the earth, it is the most reliable source of fresh water production, especially for water-stressed countries on the coasts. Middle East is an example for that since it faces arid climate and relies on desalination for fresh water by: 1.
Advances in Water Desalination is designed to meet the knowledge needs in the rapidly advancing field of water desalination, and consists of one book volume per year, containing 5–7 invited high quality timely reviews, each treating in depth a specific aspect of the desalination and related water treatment field, and written by invited top.
