Hydraulic Characteristics

Backwash

• During up-flow backwash, the resin bed should be expanded between 50% and 70% in volume for at least 10 to 15 minutes.
• This operation frees particulate matter, clears bubbles and voids, and reclassifies resin particles.
• Approximately 30 minutes of expansion is usually sufficient when first putting into service.
• Bed expansion increases with flow rate and decreases with influent fluid temperature.
• Caution is advised to avoid resin loss through the top of the vessel due to over-expansion.

Pressure Drop

• The pressure drop across a resin bed depends on particle size distribution, bed depth, void volume, flow rate, and influent solution viscosity.
• Factors such as filtered 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 influent water quality, application, and plant design.
