  2. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    Such plants can operate at 23–27 kWh/m 3 (appr. 90 MJ/m 3) of distilled water. [5] Because the colder salt water entering the process counterflows with the saline waste water/distilled water, relatively little heat energy leaves in the outflow—most of the heat is picked up by the colder saline water flowing toward the heater and the energy ...

  3. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    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

  4. Low-temperature distillation - Wikipedia

    en.wikipedia.org/wiki/Low-temperature_distillation

    Also, the effluent of existing sea water desalination plants can be treated further in a low temperature distillation to maximise the dewatering capacity of a desalination system. Low temperature distillation can accommodate variations in the plant load, running efficiently from 50 – 100% of plant design capacity depending on the available ...

  5. Multiple-effect distillation - Wikipedia

    en.wikipedia.org/wiki/Multiple-effect_distillation

    The salt water collected at the bottom of each stage can be sprayed on the tubes in the next stage, since this water has a suitable temperature and pressure near or slightly above the operating temperature and pressure in the next stage. Some of this water will flash into steam as it is released into the next stage at lower pressure than the ...

  6. Low-temperature thermal desalination - Wikipedia

    en.wikipedia.org/wiki/Low-temperature_thermal...

    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 ...

  7. Vapor-compression desalination - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_desalination

    The VVC process is the more efficient distillation process available in the market today in terms of energy consumption and water recovery ratio. [1] As the system is electrically driven, it is considered a "clean" process, it is highly reliable and simple to operate and maintain.

    Still, Mitchell said he thinks desalination has a place in California’s water portfolio,and noted that it has already proved viable in Australia and Israel, which gets nearly 90% of its drinking ...

  9. Reverse osmosis plant - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis_plant

    Nearly 17% of drinking water in Perth, Australia comes from a reverse osmosis plant that desalinates sea water. [14] Perth is an ideal candidate for reverse osmosis plants as it has a relatively dry and arid climate where conventional freshwater resources are scarce, yet it is surrounded by ocean. [ 15 ]
