Cogeneration can provide usable heat for desalination in an integrated, or "dual-purpose", facility where a power plant provides the energy for desalination. Alternatively, the facility's energy production may be dedicated to the production of potable water (a stand-alone facility), or excess energy may be produced and incorporated into the ...
Direct methods use thermal energy to vaporize the seawater as part of a 2-phase separation. Such methods are relatively simple and require little space so they are normally used on small systems. However, they have a low production rate due to low operating temperature and pressure, so they are appropriate for systems that yield 200 m 3 /day. [14]
Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity-driven ...
The brine and condensate still carry a small amount of heat that is lost from the system when they are discharged. The heat that was added in the heater makes up for this loss. [citation needed] The heat added in the brine heater usually comes in the form of hot steam from an industrial process co-located with the desalination plant.
In China a desalination plant was planned for Tianjin in 2010, to produce 100,000 m³ of desalinated seawater a day. [ 9 ] [ 10 ] In Spain in 2004, 20 reverse osmosis plants were planned to be built along the Costas, expecting to meet slightly over 1% of Spain's total water needs.
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 ...
Schematic of a multiple effect desalination plant. The first stage is at the top. Pink areas are vapor, lighter blue areas are liquid feed water. Stronger turquoise is condensate. It is not shown how feed water enters other stages than the first. F - feed water in. S - heating steam in. C - heating steam out. W - Fresh water (condensate) out.
