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.
