The answer to your question is no, simple membrane-like desalination removes total dissolved solids (TDS), or salt, from water. If there is a thermal component added to the process it can remove some metals, but usually not heavy metals like zinc, aluminum, barium, etc. Desalination does not treat volatile organics, like benzene. Nor radium, if it exists. You can understand this better just by asking what's-his-name, here:

There is NO way this water can pass whole effluent toxicity testing simply by reducing TDS. No way, not under EPA methodology using the right test organisms.

Desalination creates a waste stream, a brine like sludge that has to be disposed of in the ground, and its way worse that high TDS produced water.

There ARE standards for effluent discharges in Texas for an array of industry, including the oil and gas industry. The Permian tight oil sector does not like those standards…

All extended reach wells from pads built in the permafrost; some laterals as long at 4 miles, or more, some very short laterals, some deviations to various undrained reservoirs on different structures.

The average cumprod. of wells in this AOI is 3,000,000 BO and 3 BCF, but there are some 15 and 18,000,000 barrel and 40 BCF wells in the mix.

You've heard me rant before about EOG's "grip it and rip it" operational style, here is a cool example, below, of what I mean...

EOG and Anadarko in the Delaware Basin, above, several years back but still very relevant today. EOG has never met a choke it liked and essentially guts their wells for maximum cash flow. Anadarko, on the other hand, practiced some level of pressure preservation/reservoir management by restricting IPs.

As a result, Anadarko wells were better wells.
