I was on the U.S.S.Constellation in the 70's. The ship's desalination systems were a mess and in need of major repairs. We were due to go home but were called to the Indian Ocean instead for a " show of force ". It got to the point just getting a drink of any water was nearly impossible. No showers, no laundry and no water coolers. We would sneak into the officers mess at night to fill cans of water to drink and that even reeked of jet fuel. Being over 140 degrees F on the flight deck we were dropping like flies. After all these years later I still treat water like gold.

Priority order for water from the evaps is: Boilers Galley "Hotel Services" Showers/Laundry/General cleaning. Blame the lack of water on the CO, not engineering. That Oiler that kept your JP-5 topped off was quite capable of transferring raw distilled water, boiler feed, or potable water. All he needed to do was swallow his pride, admit that his ship had a problem, and order up a few thousand gallons. That's why there was a padeye for the RAS cables installed near the Water Inlet... The Evaps were considered critical engineering equipment. Spare parts up to and including complete units should have sailed with the battle group on one of the Replenishment ships. If not available onboard, then whatever was needed should have been airlifted out to the BG or closest shore installation and cross-decked until it made it to where it was needed. Again, a possible pride issue...First step is to admit that your ship has a problem. From the carrier POV, a matter of ordering the parts and letting the support ships handle the logistics. As far as petroleum products in the water goes, there was a leakage issue or somebody screwed up and put the wrong liquid in the wrong tank. I spent my time on a Replenishment Oiler that carried more fuel than your carrier did, and NEVER noted anything indicating a contamination issue. With 5 million gallons of DFM (Boiler fuel) and 2.5 million gallons of JP-5 onboard in like 20 tanks, I'm sure that there was ample opportunity for a screw up, but it never happened.

Whatever RATE, FALLS UNDER THE PROCUREMENT OF THIS OPERATION, has THE MOST "IMPORTANT", and TAKEN FOR "GRANTED" JOB ON ALL US WARSHIPS. NON COMBAT VESSELS, included.

Correcting some of your issues, 1) Nimitz class aircraft carriers do not use Reverse Osmosis (RO) units to make distilled water. they use 4 7 stage vacuum type distilling units. each one is rated to 100000 gallons of water a day. the ships normal operations normally only need 2 in service to make up for all operations a Nimitz class carrier can do. 2) the water from these distilling units are so pure, they have to add salts back to the waters before it is aloud for human consumption. reactor and steam plant water purity requirement require the water made is grade 1 water. RO units are not capable of producing Grade 1 water in the quantities required for a Nimitz class carrier's continuous operation. the major loss of water onboard a Nimitz class aircraft carrier is from its steam catapult systems. Sources: Myself - Reactor Operator for Nimitz class Aircraft Carriers RPM/SPM CVN-68 class Steam Catapult Tech manual CVN-68 class.

I served two combat tours (1972-1974) as an AT in Vietnam aboard the USS Ranger (CVA-61). I've learned since then that the desalination processes also drew in Dioxin, as in Agent Orange. When Dioxin & salt water merge, Dioxin becomes 10X's more potent. The Ranger's water system became so contaminated with Dioxin, as in 100 years worth, the Ranger, along with other Blue Water ships, was scrapped completely! I defer to "Military Intelligence" to cover up the evidence. Thank you, Monsanto & DOW Chemical!

Dioxin? Ever hear the line "Hook, line, and sinker"? Somebody fed you the whole tackle box... The "Desilination processes" onboard ships of the time was Distillation, resulting in chemically pure distilled water. We're not talking the "distilled water" your wife buys for her iron to iron her dresses, we are talking literally Lab Grade distilled water. Trace minerals need to be ADDED to this water to make it safe to drink. I'm guessing that you are a follower of an organization with the initials BWNVVA. They have ONE major goal for existence, that being to ensure that you are scared by their propaganda enough to pay your annual dues and contribute regularly in order to run their bank account up as high a possible. This organization makes much of using "contaminated" inshore water for production of shipboard potable water. The reality is that the regulations exist in order to prevent fouling of the Evaporator intake filters due to the higher levels of marine organisms and other solids found in inshore waters. The "scientific tests" which show that the distillation process would actually INCREASE the Dioxin content of the final product used distillation methods not even close to what the Navy was using in the 60's and 70's, and failed to include the additional steps taken AFTER distillation. FWIW, it wasn't potable water contamination which caused older ships to be removed from service, it was the fact that firing boilers with oil is very expensive.

@@DGill48 I found myself unable to construct a tinfoil hat sufficient to completely understand the theory, but it appears that they are blaming it on a combination of taking on contaminated water from shore-based municipal water and using ship's distilling equipment while close inshore where the waters were contaminated. Apparently the Dioxin was not detectable during the battery of tests ran before introducing water from ANY source into the ship's potable water tanks. To improve throughput and increase efficiency, shipboard Evaporators run at a vacuum to drop the vaporization temperature. Raw water is pumped through the Evaps and a small amount is vaporized and condensed, with the remainder going overboard. I could almost see 1,4-Dioxin with a BP of 75C/167F ending up in the condensate, but (at least in the 80's) hydrocarbons and chlorine compounds were specifically tested for, as were dissolved flammable gasses. In any case, Evaps were generally secured while running close to shore to avoid processing raw feed which might be contaminated with chemicals, bio load, silt, etc. Due to the low-temp distillation process, a heavy bio load wreaks havoc on the Bromination process used for treatment, and NOBODY wants to tear down and clean the Evaps. Backing up a bit, the Evap output goes to holding tanks, is tested, pumped to specific tanks, and is then pulled from those tanks and treated appropriately for either Boiler Feed or Potable Water for storage as appropriate. The Evap output is pretty much lab-grade distilled water. First purity test is a pretty sensitive Conductivity Test. Single-digit readings in the uA range are enough to divert the Evaps to the bilges. After that comes lab testing. If it passes it either gets Boiler Chems or trace minerals and Bromine.

Ok so why not just make a ship that only desalinates ocean water while collecting drinking water? It could be used by military, private, or commercial vessels, or shipped to an area in crisis if needed.

It’s called freshwater generator, you evaporate seawater then condensate it. And a device called salinometer will test it’s salinity if it’s already safe to drink at a certain ppm.
