ABSTRACT:
A rollover type car wash and rinse machine which uses permeate from a reverse osmosis unit for a final rinse operation. The machine is operator controlled to wash and initially rinse cars with a spray arch using raw water and concentrate from the reverse osmosis unit. A final rinse can then be performed with a second spray arch using permeate alone, and only after a wash and initial rinse has been performed.
