In this paper design and analysis of energy, exergy, economic and the environmental impacts (4E) of direct twostage reverse osmosis (RO) system have been optimized for supplying Miarkelar water, north of Iran using multiobjective optimization. In this city, water has been provided for a period of 20

Depletion of fresh groundwater sources as the result of overdraft, salinization and pollution becomes a major problem in parts of the world. Desalination of brackish groundwater by membrane technology, e.g. reverse osmosis (RO), seems to be a promising solution to water scarcity problems. However, e

The growth in population and in the standard of living in the developing countries coupled with inefficient use of water and pollution of available water resources have driven desalination to be a major source of fresh water for both domestic and industrial purposes. The potential environmental impac

Lake Victoria basin has a large rural and rapidly growing peri-urban population that lacks sustainable solutions to safe and adequate water supply, energy and sanitation. Access to safe water and sanitation was 60% and 53%, respectively, by 2006. An Integrated Water, Energy and Sanitation Solution (

Salinity gradient power (SGP) is based on the chemical potential difference between concentrated and dilute salt solutions. Reverse electrodialysis (RED) can thus be used to produce electricity by a SGP–RED unit. In principle, a highly concentrated solution can be recovered from a seawater desalinat

A thermoeconomic analysis of a cogenerative system with steam bleedings produced starting from the thermal energy recovered in a municipal solid waste thermovalorization plant is presented. The authors assume that the bled steam is used to feed a seawater multi-stage flash (MSF) desalination plant.

This paper relates to the energetic and exergetic analysis of single-, double- and triple-effect distiller driven by solar energy. Energetic analysis makes it possible to define an applicable zone of operation according to the following criteria: water rejection limit to 50%, maximum salinity limit

We present an analysis of energy and exergy utilization in the utility sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years 1990–2001. Energy and exergy analyses were conducted for its two subsectors, namely power-only plants and power/distillation plants, and hen

La récente conférence de la Haye, sous l’égide du Conseil Mondial de l’Eau, a eu le mérite de rappeler avec insistance que la rareté de l’eau dans de vastes contrées du Monde a un caractère autant géophysique qu’économique: les investissements nécessaires pour renverser la tendance à la pénurie et m
