RO/DI Question

[Hendersonracing]

Ok quick question....We have a big car wash here at work with a ro/di unit on it..But they are not getting anywaste water...what is the purpose of the waste water and how do these units work....I get alot of waste water with my ro-di at home, I thought it just split up the water

are you sure it is RO/DI? the waste water is where all of the impurities go from the RO.

I would guess it is a highend filter setup and not a RO/DI. I dont see the purpose for a RO unit at a carwash, but I do with a good filter setup.

Because spots on the car just suck
