  2. Evaporator (marine) - Wikipedia

    en.wikipedia.org/wiki/Evaporator_(marine)

    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 ...

  3. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    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 ...

  4. Reverse osmosis - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis

    RO is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules. [ 2 ] As of 2013 the world's largest RO desalination plant was in Sorek, Israel , outputting 624 thousand cubic metres per day (165 million US gallons per day).

  5. Watermaker - Wikipedia

    en.wikipedia.org/wiki/Watermaker

    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.

  6. Reverse osmosis plant - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis_plant

    Nearly 17% of drinking water in Perth, Australia comes from a reverse osmosis plant that desalinates sea water. [14] Perth is an ideal candidate for reverse osmosis plants as it has a relatively dry and arid climate where conventional freshwater resources are scarce, yet it is surrounded by ocean. [ 15 ]

  7. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    Companies may use seawater for this process due to its low cost. The water used is usually brackish water or brine (i.e. a solution with >0.5% salinity). In these cases, additional contaminant chemicals may be present in the water feed. The low voltage DC current still performs electrochlorination.

  8. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    The drinking of distilled water as a replacement for drinking water has been both advocated and discouraged for health reasons. Distilled water lacks minerals and ions, such as calcium, that play key roles in biological functions, such as in nervous system homeostasis, and are normally found in potable water. The lack of naturally occurring ...

  9. Claude "Bud" Lewis Carlsbad Desalination Plant - Wikipedia

    en.wikipedia.org/wiki/Claude_"Bud"_Lewis_Carlsbad...

    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]
