  • The growing use of composite materials in the desalination process

    The vast majority of the Earth’s surface is covered by saltwater and people living on the remaining land need fresh water to sustain life. But, as our readers are well aware, more than 1 billion people lack reliable access to fresh water and that count is only expected to grow. Remarkably, almost 60 percent of the world’s population lives less than 60 km from a seacoast. Desalinated ...

  • Low-pressure desalting membranes for seawater

    The Long Beach Water Department (LBWD), similar to many Southern California utilities, have been facing the issue of decreased potable water supplies. Because of its location, the City of Long Beach is ideally situated to take advantage of desalinated seawater as a source of drinking water. However, the primary barrier to seawater desalination has been its relatively high cost as compared to ...

  • Effects of drinking desalinated seawater on cell viability and proliferation

    Desalination of seawater is becoming an important means to address the increasing scarcity of freshwater resources in the world. Seawater has been used as drinking water in the health, food, and medical fields and various beneficial effects have been suggested, although not confirmed. Given the presence of 63 minerals and trace elements in drinking desalinated seawater (63 DSW), we evaluated ...

  • Present and future activities of nuclear desalination in Japan

    Seawater desalination plants have been installed at several nuclear power plants in Japan in order to satisfy the regulations for nuclear plant installation. This has been done where there is a limited source of water due to the geological conditions. These desalination plants are being operated to ensure supplemental water by using thermal or electrical energy from the nuclear power plant. The ...

  • Impact of elevated Ca2+/Mg2+ concentrations of reverse osmosis membrane desalinated seawater on the stability of water pipe materials

    Hardness and alkalinity are known factors influencing the chemical stability of desalinated water. This study was carried out to investigate the effect of Ca2+ and Mg2+ on corrosion and/or scale formation on the surface of different water distribution pipe materials under tropical conditions. The corrosion rates of ductile iron, cast iron and cement-lined ductile iron coupons were ...

  • Utilizing available `coldness` from Liquefied Natural Gas (LNG) regasification process for seawater desalination

    Abstract With the increasing use of natural gas, Liquefied Natural Gas (LNG) is becoming more extensively used to ease the storage and transport of gas. The process of returning the natural gas to its gaseous state (regasification) prior to distribution to the gas pipeline absorbs large quantities of heat and therefore provides a readily available and inexpensive source of "coldness" at low ...

  • Prospects of nuclear desalination in Morocco

    In the last few years, Morocco has faced a continuous series of dry seasons, which has put a great stress on its limited water resources. Hence, for some time now Morocco has been considering desalinating seawater to supply fresh water to some areas. In the early 1980's, due to limited energy resources, Morocco was obliged to consider other alternatives to meet its energy demands. A feasibility ...

  • Innovative seawater intake for reverse osmosis desalination plants

    Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...

  • Optimum thermal coupling system for co-generation nuclear desalination plants

    Owing to the small number of established nuclear desalination plants worldwide, there is a lack of technical data and not enough practical experience in the field of coupling systems. Therefore, in this study different coupling technologies concerning co-generation systems for linking nuclear power reactors to large thermal seawater desalination units (MED and MSF) are reviewed and optimised. ...

  • Seawater desalination and serum magnesium concentrations in Israel

    With increasing shortage of fresh water globally, more countries are consuming desalinated seawater (DSW). In Israel >50% of drinking water is now derived from DSW. Desalination removes magnesium, and hypomagnesaemia has been associated with increased cardiac morbidity and mortality. Presently the impact of consuming DSW on body magnesium status has not been established. We quantified ...

  • Water reuse in the Kingdom of Saudi Arabia – status, prospects and research needs

    Saudi Arabia is one of the driest countries in the world. While desalination plants currently installed in the country represent 30% of the world's desalination capacity, seawater desalination alone will not be able to provide sufficient supplies to meet the increasing freshwater demand. However, with only 9% of the total municipal wastewater generated currently being ...

  • Status and prospects of nuclear desalination

    Recent statistics show that currently 2.3 billion people live in water-stressed areas and among them 1.7 billion live in water-scarce areas. In the light of this, the Millennium Declaration by the UN General Assembly in 2000 has set up a target to halve, by the year 2015, the world population who are unable to reach, or to afford, safe drinking water. Better water conservation, water management, ...
