COST EVALUATION OF DESALINATION PLANTS - BISAC: 1: TEC005050 Technology & Engineering : Construction - HVAC 2: TEC009070 Technology & Engineering : Mechanical 3: TEC010030 Technology & Engineering : Environmental - Water Supply The quality with which water is released from desalination plants is continuously increasing. Since desalination permeates are slightly acidic, contain very low buffering capacity and are very soft, posttreatment is always required. This paper reviews the knowledge accumulated in the last decades on desalination post-treatment processes. It covers fundamental chemistry aspects, required water quality criteria, advantages and disadvantages of currently applied processes, engineering and cost considerations, recent full-scale project experience and up-to-date research trends. A full discussion of the engineering involved in the construction of reverse osmosis desalination plants including basic concepts, raw water requirements, materials needs, pressure vessels and racks, reverse osmosis pumps, recovery systems, and more.
