Cleaning up fracking water

Safe fracking

Injecting higher pressure water into shell formations, does liberated oil.  But does are also are the 37 times the volume of contaminated water.

Which ooil company is have started injecting the into deep rock formations.  They potentially disastrous results!  Causing Earth quakes.

The answer is my old friend of vacuum desalination.  We apply one metre of vacuum to brown water, and suck out pure water.  Leaving behind a thick sludge, we need to use time reprocessing techniques to deal with.

To reject back down into the shale formation.  And now we do not interact the contaminated water, so we get no earthquakes.

We removing ooil bound up in the sales.  Which are a major energy reserve globally.  But now we avoid the earthquake problem.

There is no temptation to inject large volumes of brown water into the deep earth.  The immune to potential contamination forms the local lakes and Rivers.  It is not really hard science!
