Comment on Desalination system could produce freshwater that is cheaper than tap water
assassin_aragorn@lemmy.world 1 year agoYes and no. I get what you’re saying. No wash is 100% efficient, nor does it have to be. It’s just going to set the number of runs the unit can do before it needs to go offline for more intensive cleaning. Short run times though lead to more expensive operation. What this work does is increase the run time by more efficiently removing salt.
Do you get what I mean? Long term salt buildup is going to cause problems, and the more slowly you can make that happen, the better.

salt is not limestone

What does that have to do with anything?

limestone deposited by water leads to a hard, not easy to remove build up as it will not readily redissolve into any water, unlike salt, that will gladly let its self be dissolved via osmotic pressure until the maximum salinity of water is reached
seawater for example has around 34-35 ppt salt, water is satisfied at around 260ppt, meaning that one saltwater flush of the system will clean out basically all the salt of like 7 prior runs
