Suggested Operating Conditions

Beet Molasses (K⁺ form)

• Syrup Temperature: 80 – 85°C (176 – 185°F)
• Syrup pH: 7 – 12
• Dissolved Oxygen Concentration: Recommended < 0.1 ppm, Maximum 0.25 ppm

Simulated Moving Bed Operation

• Oxygen should be removed from feed streams and elution water.
• Limiting dissolved oxygen to less than 0.1 ppm (0.25 ppm maximum) is recommended to maximize resin life.

Hydraulic Characteristics

Information regarding bed expansion as a function of backwash flowrate and pressure drop as a function of service flowrate for the 350-µm size is available, along with thermal expansion data. Equations are provided for calculating these parameters at different temperatures.
