*1 BV (Bed Volume) = 1 m³ solution per m³ resin or 7.5 gal per ft³ resin

Hydraulic Characteristics

• Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 1.
• Estimated pressure drop as a function of service flowrate and viscosity is shown in Figure 2. These pressure drop expectations are valid at the start of the service run with clean feed and a well-classified bed.
• Temperature (for figures): 5 – 60°C (41 – 140°F)
• Viscosity (for figures): 1 – 10 cP
