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 ...
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 polyamide film is a dense, void-free polymer with a high surface area, allowing for its high water permeability. [64] A recent study has found that the water permeability is primarily governed by the internal nanoscale mass distribution of the polyamide active layer. [65] The reverse osmosis process requires maintenance.
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.
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.

Artificial seawater (abbreviated ASW) is a mixture of dissolved mineral salts (and sometimes vitamins) that simulates seawater. Artificial seawater is primarily used in marine biology and in marine and reef aquaria , and allows the easy preparation of media appropriate for marine organisms (including algae , bacteria , plants and animals ).
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 ...
Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options.
