Would I drink the recycled water - No.
Is this "road dirt" like "sandblasting your car" - No
If you took some recycled water and looked at it through a clear glass it may not be exactly as clean as drinking water, but I promise you that no sand/dirt is in their. If that was the case, equipment would constantly be failing. The high pressure tips in the wash gun can't pass a grain of sand. I've had cases where I contaminated my PW when I hooked up a gritty garden hose and it blocked my tip later on. I have a similar model PW that Coin-Op's use.
And media/gravirty filtration probably does remove most of the solid dirt in the water, however what else is left in the water? The big problem is that there is no labeling of what is what, its all a crap shoot. Yes some of the washes use fresh water, but others for sure use recycled. I'm not a fan of blasting "treated" water into anything on my car.
Example of using recycled:
Weidner Coin operated self service car wash systems
and there are plenty more if you google "coin operated car wash water recycling" you will find plenty more. While I'm sure it is fine for the masses, it certainly isn't autopian, and I hope no one is fooled into thinking its as clean as the stuff at home.
