Reverse osmosis desalination plant in Barcelona, Spain. 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]
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.
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.
El Paso Water is planning to boost average water bills by $3.54 per month. An expansion of the Kay Bailey Hutchison Desalination Plant is planned.
According to the International Desalination Association, for 2011, RO was used in 66% of installed desalination capacity (0.0445 of 0.0674 km 3 /day), and nearly all new plants. [22] Other plants use thermal distillation methods: multiple-effect distillation , and multi-stage flash .

The future of what may become the Coastal Bend’s first desalination plant will likely soon become more clear after years of lengthy discussions and heated debate.
Waste heat from the power plant is used to heat the seawater, providing cooling for the power plant at the same time. This reduces the energy needed by half to two-thirds, which drastically alters the economics of the plant, since energy is by far the largest operating cost of MSF plants. Reverse osmosis, MSF distillation's main competitor ...
