Vapor-compression evaporation involves using either a mechanical compressor or a jet stream to compress the vapor present above the liquid. [56] The compressed vapor is then used to provide the heat needed for the evaporation of the rest of the sea water. [55] Since this system only requires power, it is more cost effective if kept at a small ...
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 ...
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] Due to the complexity for modeling ion transport phenomena in the channels, performance could be affected, considering the non-ideal behavior presented by the exchange ...
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 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 Safe Drinking Water Act, which was passed by Congress in 1974, regulates the country’s drinking water supply, focusing on waters that are or could be used for drinking. This act requires ...

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]
