    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 ...

    en.wikipedia.org/wiki/Water_resources

    Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...

    The flow of water can be reversed if a pressure larger than the osmotic pressure is applied on the higher concentration side. In Reverse osmosis desalination systems, seawater pressure is raised above the natural osmotic pressure, forcing pure water through membrane pores to the fresh water side. Reverse osmosis (RO) is the most common ...

    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]

    where X is the exchange site on the soil particles. [51] Compared to seawater, the water in the transition zone would have excess calcium and be depleted in sodium. Compare with fresh water, it is the opposite case. Other cations like magnesium and potassium exchange as well. Magnesium and calcium would be exchanged for sodium. [11]
