You are referring to vacuum flash evaporation used for making drinking water
quality.
We operated such an (early) plant between approx 1970 and 1990 and know
about the costs involved. Later on these plants were built in the
Middle-East and elsewhere.
So we are in a position to compare with membrane technology.

Membrane technology made big strides forward lately.
In fact, the older vacuum flash plant above (not in our realm anymore) is
currently being replaced by a membrane plant (by others).
Client being a hugh US chemical international, so the bucks do count!

By the way: you did not answer my question:
