Hydraulic Characteristics

Backwash

During up-flow backwash, the resin bed should be expanded between 50% and 70% for at least 10 to 15 minutes. Bed expansion increases with flow rate and decreases with influent fluid temperature. Caution should be taken to avoid resin loss by over-expansion.

Pressure Drop

The pressure drop across the resin bed depends on particle size distribution, bed depth, voids volume, flow rate, and influent solution viscosity. Factors such as particulate matter, abnormal resin compressibility, or incomplete bed classification can increase head loss. Service flow rates may vary from 10 to 40 BV/h depending on water quality, application, and plant design.
