SCRUBBING SYSTEM OPERATING INSTRUCTIONS
THE RECOVERY OR ESP SCRUBBING SYSTEM - HOW IT WORKS
During the scrubbing process (shown in Figure 15), fi ltered water from the solution tank is fed to the solution line, where it combines with detergent
from the metering pump. This mixture is then fed to the fl oor where three disc scrubbing brushes work to dislodge soil.
After scrubbing, the dirty solution is vacuumed from the fl oor and discharged into the containment chamber in the forward portion of the recovery
tank, where a system of baffl es helps to clarify the solution on its way to the pumping chamber in the rear of the recovery tank. At intervals, a system
of sensors activates the recycling pump, which sends fi ltered solution from the pumping chamber on its way to the solution tank. Here, it is ready to
be mixed with fresh, metered detergent and repeat the cycle.
