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.
Since 1975, desalination technology has seen significant advancements, decreasing the average cost of producing one cubic meter of freshwater from seawater from $1.10 in 2000 to approximately $0.50 today. Improved desalination efficiency is a primary factor contributing to this reduction.
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.
Technology innovation is needed to deliver autonomous, precise, resilient, intensified, modular, and electrified desalination systems that reduce the cost, improve the performance, and enhance the resilience of nontraditional water reuse systems. [10]
New estimates for the construction portion of the project are more than double – originally thought to cost about $220 million, costs are now estimated to reach about $541.5 million.
Electrodialysis reversal (EDR) is an electrodialysis reversal water desalination membrane process that has been commercially used since the early 1960s. [1] An electric current migrates dissolved salt ions, including fluorides, nitrates and sulfates, through an electrodialysis stack consisting of alternating layers of cationic and anionic ion exchange membranes.
California has awarded $120 million for desalination projects, compared to $1.4 billion on charging stations and $500 million for electric school buses. The California Air Resources Board has the ...
Low-temperature thermal desalination (LTTD) is a desalination technique which takes advantage of the fact that water evaporates at lower temperatures at low pressures, even as low as ambient temperature. The system uses vacuum pumps to create a low pressure, low-temperature environment in which water evaporates even at a temperature difference ...
