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 design for cooling the microclimate primarily consists of humidification and dehumidification (HD) desalination process or multiple-effect humidification. [9] A simple seawater greenhouse consists of two evaporative coolers (evaporators), a condenser, fans, seawater and distilled water pipes and crops in between the two evaporators. [10]
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.
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]
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]
Desalination is the process of removing minerals from seawater to convert it into fresh water. Desalination is divided into two categories in terms of processes: processes driven by thermal energy and processes driven by mechanical energy. [3] Geothermal desalination uses geothermal energy as the thermal energy source to drive the desalination ...
