Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. [1]
Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. [1] One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to
Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them.
The first method utilizes an ejector system motivated by steam at manometric pressure from an external source in order to recycle vapor from the desalination process. The form is designated ejectocompression or thermocompression. Using the second method, water vapor is compressed by means of a mechanical device, electrically driven in most cases.
The LTD process is most suitable for high saline feedwaters starting from typical concentrations of sea water to concentrated wastewater solutions from various industrial processes. [10] One possible application is the capacity duplication of RO based desalination systems by further treatment of the evolving effluents to the precipitation of salts.
Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment, concentration of contaminants, and the reclamation of dissolved minerals. [1]
The process does create some residual contaminants, but it’s less than that of desalted seawater and can be disposed of in septic tanks. Cohen said it's a promising solution not only for remote ...
Obtaining fresh water from seawater is a theoretically simple system that, in practice, presented many difficulties. While there are numerous effective methods today, early desalination efforts had low yields and often could not produce potable water. [1]
