  2. 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 produce water for human consumption or irrigation.

  3. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    High grade water recycling. Wave-powered desalination. 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.

  4. 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. As the system is electrically driven, it is considered a "clean" process, it is highly reliable and simple to operate and maintain.

  5. Zero liquid discharge - Wikipedia

    en.wikipedia.org/wiki/Zero_Liquid_Discharge

    Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation ). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received. [ 1][ 2] ZLD technologies ...

  6. Multiple-effect distillation - Wikipedia

    en.wikipedia.org/wiki/Multiple-effect_distillation

    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. Some of the water evaporates, and this steam flows into the tubes of ...

  7. Membrane distillation - Wikipedia

    en.wikipedia.org/wiki/Membrane_distillation

    Membrane distillation ( MD) is a thermally driven separation process in which separation is driven by phase change. A hydrophobic membrane presents a barrier for the liquid phase, allowing the vapour phase (e.g. water vapour) to pass through the membrane's pores. [ 1]

  8. Electrodialysis reversal - Wikipedia

    en.wikipedia.org/wiki/Electrodialysis_reversal

    Wave-powered desalination. Electrodialysis reversal ( EDR) is an electrodialysis reversal water desalination membrane process that has been commercially used since the early 1960s. [1] An electric current migrates dissolved salt ions, including fluorides, nitrates and sulfates, through an electrodialysis stack consisting of alternating layers ...

  9. Low-temperature distillation - Wikipedia

    en.wikipedia.org/wiki/Low-temperature_distillation

    Fig. 1: Two water columns with different temperatures. Low temperature distillation (LTD) is a thermal distillation process in several stages, powered by temperature differences between heat and cooling sources of at least 5 K per stage. Two separate volume flows, a hot evaporator flow and a cool condenser flow, with different temperatures and ...
