Water Reuse System
The CBL utilizes a water reuse system that filters water discharged from the washers and stores it in a
reuse tank for use in subsequent wash loads. Water from the washer is discharged from a reuse drain
into the Water Treatment System (WTS) transfer tank (Figure 4, Item 1) located behind the washers.
When the WTS transfer tank is full, the untreated water is pumped up to a WTS holding tank (Figure 4,
Item 2) located over the washers. Pump P-3 (Figure 4, Item 3) takes water from the WTS hold tank and
sends it through the F-1 (Figure 4, Item 4) and F-2 (Figure 5, Item 5) filters to remove gross impurities.
Water is then routed to the nanofilter feed tank (Figure 5, Item 6) for collection. Water from the nanofilter
feed tank is fed into Pump P-4 (Figure 5, Item 7) and through a series of three nanofiltration vessels
(Figure 5, Item 8) that remove all remaining impurities and bacteriological products. Water then passes
through carbon filter F-3 (Figure 5, Item 9) and is stored in the reuse tank (Figure 5, Item 10) for later
