This steam evaporator aboard HMS Belfast distilled up to six tons of fresh water per hour for the boiler and for drinking. An evaporator, distiller or distilling apparatus is a piece of ship's equipment used to produce fresh drinking water from sea water by distillation. As fresh water is bulky, may spoil in storage, and is an essential supply ...
Costs of desalinating sea water (infrastructure, energy, and maintenance) are generally higher than fresh water from rivers or groundwater, water recycling, and water conservation, but alternatives are only sometimes available. Desalination costs in 2013 ranged from US$0.45 to US$1.00/m 3. More than half of the cost comes directly from energy ...
The feed water passes in parallel through all the cells, providing a continuous flow of permeate and brine. Although this is a well-known process electrodialysis is not commercially suited for seawater desalination, because it can be used only for brackish water (TDS < 1000 ppm). [38]
The similar Carlsbad Desalination Plant has been operated by Brookfield Infrastructure Partners-owned Poseidon Water since 2015. [7] The sea water intakes from the 1950s-era plant will now be used to pull ocean water in for desalination as the AES power generating plant is being rebuilt to use air instead of sea water to cool the plant.

Chemical is highly diluted. Drinking water. Brackish 1000-10000 Evaporation of groundwater increases the chemical concentration of water. Or intrusion of seawater increases the chemical concentration of water. Water is too saline to be drinkable. [47] Saline 10000-36000 Similar to seawater. Strong evaporation of groundwater or fully mixing with ...
The cost of water from the plant will be $100 to $200 more per acre-foot than recycled water (approximately 0.045 cents per gallon), $1,000 to $1,100 more than reservoir water (approx. 0.32 cents per gallon), but $100 to $200 less than importing water from outside the county. [42] As of April 2015, San Diego County imported 90% of its water. [13]
A watermaker is a device used to obtain potable water by reverse osmosis of seawater. In boating and yachting circles, desalinators are often referred to as "watermakers".. The devices can be expensive to acquire and maintain, but are quite valuable because they reduce the need for large water tanks for a long passage.
In Australia many desalination plants are utilizing wind farms to produce enough energy to operate nearby desalination plants. For example, the Kurnell Desalination Plant, with a capacity of producing 250 million liters (ML) of drinking water per day, supplies 15% of Sydney's water needs via RO technology and is powered using "100 percent renewable energy" from the 140 MW Capital Wind Farm.
