The solar humidification–dehumidification method (HDH) is a thermal water desalination method. It is based on evaporation of sea water or brackish water and subsequent condensation of the generated humid air, mostly at ambient pressure. This process mimics the natural water cycle, but over a much shorter time frame.
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
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]
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 th
Low-temperature thermal desalination (LTTD) is a desalination technique which takes advantage of the fact that water evaporates at lower temperatures at low pressures, even as low as ambient temperature. The system uses vacuum pumps to create a low pressure, low-temperature environment in which water evaporates even at a temperature difference ...
David Feldman, director of Water UCI at UC Irvine, said desalination could eventually provide "somewhere between 10% and half" of California's potable water — with one caveat.
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]
1. Constructing a seawater desalination plant, that uses the reverse osmosis desalination process, where two liters of sea water are taken in, producing one liter of drinkable water and a second liter of very salty water , which is returned to the sea. [1] [4] A three-year operation and maintenance period is part of the EPC contract. [6] 2.
