Distill drinkable water from ocean

By From page A10 | February 21, 2014

The Enterprise of Feb. 16 has an article on Page A2 from the Associated Press on President Obama’s statement about satisfying California needing water. No mention is made of the never-ending supply from the ocean along 800 miles of California coast. Also no one anywhere mentions how California’s abundant sunshine can be utilized to distill drinkable water.

Such water would require little further, often costly, purifications as occurs with much fresh water. That water would need much less treatment with chlorine, reducing greatly the unneeded formation in drinking water treatments of halogenated chlorinated hydrocarbon that escape to cause ozone depletion.

The situation is more drastic than just drought as the huge agricultural enterprise along the coastline is finding that some wells used to irrigate are getting salt water seeping in. That could curtail a big part of a multibillion-dollar industry for the state.

Can someone get state leaders to forget the crazy concept of shipping of Northern California water to Southern California and to start calling for using mirrors to concentrate the sun’s energy in distilling set-ups to get drinkable water? Another reason to get water from the ocean along the coast is that water channels from NorCal to SoCal may get busted open in an earthquake.

What kind of mess could that make for the state?

A further benefit arises from using the solar-powered distilling of ocean water. A concentrated salt solution remains, and that can be used to treat cleaned sewage water dumped in the ocean as occurs in Alameda County Water District at least. Making that cleaned sewage waste water up to ocean level in saltiness will destroy germs so that chlorinating treatments are not needed, curbing formation of ozone depletors.
