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
Improved desalination efficiency is a primary factor contributing to this reduction. Energy consumption remains a significant cost component, accounting for up to half the total cost of the desalination process. [108] Desalination can substantially increase energy intensity, particularly for regions with limited energy resources.
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.
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 ]
A Zero Liquid Discharge (ZLD) process diagram that highlights how wastewater from an industrial process is converted to solids and treated water for reuse via a ZLD plant. Concept of ZLD Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable ...
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.
Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.
