In Central California, a startup company WaterFX is developing a solar-powered method of desalination that can enable the use of local water, including runoff water that can be treated and used again. Salty groundwater in the region would be treated to become freshwater, and in areas near the ocean, seawater could be treated. [155]
The resulting fresh water is moved to storage while the heat removed during condensation is transmitted to the remaining feedstock. The VVC process is the more efficient distillation process available in the market today in terms of energy consumption and water recovery ratio. [ 1 ]
In order to overcome water scarcity, substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment. Today about 50% of drinking water comes from desalination, 40% from the mining of non-renewable groundwater and only 10% from surface water in the mountainous southwest of the country.
El Paso Water is planning to boost average water bills by $3.54 per month. An expansion of the Kay Bailey Hutchison Desalination Plant is planned.
The Thames Gateway Water Treatment Works or Beckton Desalination Plant is a desalination plant in Beckton, London, adjacent to Beckton Sewage Treatment Works. [1] The plant takes brackish water from the River Thames and converts it into drinkable water through a reverse osmosis process.
David Feldman, director of Water UCI at UC Irvine, said desalination could eventually provide "somewhere between 10% and half" of California's potable water — with one caveat. "Before we can ...
Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment, concentration of contaminants, and the reclamation of dissolved minerals. [1]
Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. [1]
