Solar desalination

It is a well-known fact that the energy used in the process of desalinating seawater is directly proportional to the amount of salt extracted from the water. Very small portions of fresh water consumed in each house is used for drinking and cooking, the rest is used for flushing, cleaning, and water

In July, 1988, the first start-up of a solar multi-effect distillation system took place at the Plataforma Solar de Almería, a solar research centre located in southeastern Spain, near Almeria. The plant, known as “Sol-14”, is still in operation. The plant was built and connected to the previous exi

The Sol-14 plant is a solar multi-effect distillation system installed at the Plataforma Solar de Almería, a solar research centre located in southeastern Spain, near Almería. In July 1988 the first start-up of the plant took place, which was connected to the previous existing solar facilities. In t

improvements of thermal solar and seawater distillation technologies were considered in order to analyze the perspectives of the competitiveness of solar vs. conventional energy in seawater desalination. Indirect solar desalination has interesting potential for development. Nevertheless, intensive r

The objective of this paper is to compare the economics of using solar energy to operate small multiple effect seawater distillation systems in remote areas with the conventional method of using fossil fuels. The particular multiple effect system used is an advanced horizontal tube, falling film sys
