The preferred cleaning flow rates are nominal product flow and reject flow base on the module
reject flow calculations in Table 6-1.
Valves and Hoses
Figure 6-1 shows a typical flow diagram for cleaning or sanitizing a VNX system. Valves are
needed for mixing, cleaning, and draining the tank.
Flexible hose is ideal for connecting cleaning equipment to the system. Verify that the
construction materials of the valves and hose are compatible with the cleaning solutions.
