Hydraulic Characteristics

Backwash

• Bed Expansion: Bed should be expanded between 50 and 70% for at least 10 to 15 minutes during up-flow backwash.
• Initial Classification: Approximately 30 minutes of expansion is usually sufficient when first putting into service.
• Factors Affecting Expansion: Bed expansion increases with flow rate and decreases with influent fluid temperature. Caution is needed to avoid resin loss due to 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 influent water quality, application, and plant design.

Typical Packaging

• 1 ft³ Sack
• 25 L Sack
• 5 ft³ Drum (Fiber)
