Freezingmelting process and desalination: review of present status and future prospects

The main factors affecting the use of freezing-melting (FM) process are the capital cost and the process complexity. The FM technology was successful when these two factors were compensated by other advantages. The success in food industry was mainly due to its ability of producing high-quality products compared to the available thermal technology in the market. In chemical industry it is ...

Prospects of nuclear desalination and highlights of related IAEA activities

Currently, several IAEA Member States have shown interest in using nuclear energy for seawater desalination, not only because recent studies have demonstrated that nuclear desalination is feasible, but also because it is economical and has already been demonstrated in several countries. Therefore, this paper will provide a highlight on seawater desalination using nuclear energy as a potential for ...

Toxic brine from desalination plants

A new study has highlighted the problem of brine discharged from desalination plants. More than half the brine comes from Saudi Arabia, the United Arab Emirates, Kuwait and Qatar, with Saudi Arabia alone accounting for 22%. 3 countries - the Maldives, Malta and the Bahamas - meet all their water needs with desalination. Not surprising when you see the islands from the air: The number of ...

Algae Bloom Detection for Desalination Plants

Despite the fact that water covers 70 percent of the planet, a mere 3 percent of that water is fresh. Most of the planet’s freshwater is not readily available. The water systems that perpetuate ecosystems are stressed by a growing human population, disappearing wetlands, agricultural consumption and droughts related to climate change. At present, 14 of the world’s 20 largest cities ...

Desalination as a game-changer in transboundary hydro-politics

This article demonstrates how the availability of seawater desalination is important, not just as an additional source of water supply on a national scale, but as a potential ‘game changer’ in transboundary hydro-political interactions. The advent of desalination can change the nature of relations from a zero-sum game based on resource capture to a mutually beneficial ...

The role and importance of nuclear desalination

Desalination needs energy and saline water as the process raw material. The desalination process where the needed energy is generated by nuclear sources and/or the saline water is supplied from a nuclear installation, such as cooling water from the power unit, is usually called nuclear desalination. Comparing nuclear desalination with alternative water sources in general and to nonnuclear ...

Safety aspects of future nuclear desalination plants: IAEA activities and world efforts

The use of nuclear reactors for seawater desalination has been investigated extensively for more than ten years and various designs of nuclear reactors have been proposed for future nuclear desalination plants. All such plants should satisfy recent safety requirements. In this paper, we firstly review the general safety requirements to be imposed on future nuclear desalination plants. Secondly, ...

Facile synthesis of novel hierarchically porous carbon derived from nature biomass for enhanced removal of NaCl

In this work, the hierarchically porous biomass carbon (HPBC) was originally prepared for desalination through a simple activation of cheap biomass carbon (BC). Such crucial activated conditions as the KOH/C ratio, the activation time and the activation temperature were deeply investigated. It is demonstrated that the activated conditions had a great influence on the structure properties and ...

WAIV- Wind Aided Intensified Evaporation for reduction of desalination brine volume

One of the challenges to inland desalination plants in arid regions is the question of brine disposal. Evaporation ponds proposed for brine disposal present an environmental burden because of the large area required. A process has been developed in cooperation with Lesico Ltd. to drastically reduce the land area required for such brine disposal. It is based on vertically mounted and ...

NIROBOX Desalination Plant in South Africa - Case Study

A high-output desalination plant was urgently needed to solve an acute potable water shortage on the parched southeast coast of Africa. Fluence answered the challenge with 10 of its Nirobox modular, containerized desalination units. The 10,000-m3/d assembly has centralized intake, post-treatment, and remote monitoring, and is fully automated. The plant was ordered and commissioned in just six ...

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 ...

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 ...

Review and evaluation of desalination cost and costing methodologies

Recently, desalination is becoming a viable alternative for supplying potable water due to new developments in desalination technologies. At present, the cost of desalinated water is about US$0.5/m³ by RO and US$ 1.0/m³ by thermal processes. But these costs are location dependent. Thus the selection of an appropriate desalination technology for any location needs a reliable and accurate costing ...
