X-Flow-RX300-0-9UFC

Summary

Product Identification

The X-flow RX-300 0.9UFC is an ultrafiltration pilot module designed for the production of process and potable water. Typical applications include the filtration of surface water, potable water, and WWTP effluent.

• Product Name: X-flow RX-300 0.9UFC
• Article Code: 1051BL895A
• Mode of Operation: Feed-and-bleed with a minor crossflow, or dead-end mode with regular backwash (permeate only) and chemically enhanced backwash.

Materials of Construction

• Housing: PSF
• Potting: EP resin
• Membrane: PES/PVP

Operating Limits

• Max. System Pressure:
  • 800 kPa [116 psi] at 20 °C
  • 600 kPa [86 psi] at 40 °C
  • 400 kPa [58 psi] at 60 °C
• Max. Transmembrane Pressure:
  • 300 kPa [43 psi] at 0-30 °C
  • 200 kPa [29 psi] at 30-60 °C
• Max. Backflush Pressure:
  • 300 kPa [43 psi] at 0-30 °C
  • 150 kPa [21.5 psi] at 30-60 °C
• Max. Temperature: 60 °C [140 °F]

Important Operating Notes:

• Avoid sudden temperature changes, particularly decreases, to prevent mechanical damage.
• Do not exceed 60 °C process temperature.
• Bring the module or element back to ambient operating temperature slowly (typical value 1 °C/min).
• Final maximum operating limits are determined by the lowest values of the membrane and element pressure and temperature specifications.

Mechanical / Hydraulic

• Membrane diameter: 0.9 mm [35.4 mil]
• Membrane area: 0.08 m² [0.86 ft²]
• Element length L0: 300 mm [11.8 Inch]
• Element outer diameter: 23.9 mm [0.94 Inch]

Process Characteristics (water 20 °C):

• Membrane diameter: 0.9 mm [35.4 mil]
• Flow rate (*): 0.27 x v [1.19 x v] m³/h/gpm (where v is superficial velocity in m/s [ft/s])
• Pressure-drop across module at 1 m/s: 11 kPa [1.6 psi]
• Pressure-drop across module at 2 m/s: 24 kPa [3.5 psi]

Backwash Considerations:

• Backwash water should be free of particulates and be of permeate quality or better.
• Backwash pumps should preferably be made of non-corroding materials (e.g., plastic or stainless steel).
• If compressed air is used to pressurize backwash water, do not allow a two-phase air/water mixture to enter the element.

Storage and Preservation

• New Modules: Can be stored as supplied in original packaging. Elements contain an aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%).
• Storage Conditions: Dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight. Store between 0 and 40 °C. Do not subject to freezing temperatures.
• Shelf Life: Maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership.
• After Use: UF membrane modules must be stored wet at all times.
  • Short-term shutdowns (1–7 days): A daily backwash with UF permeate quality water for 30 seconds at 215 lmh should be adequate for bacteria control. Before shutdown, modules must be cleaned by a standard Chemical Enhanced Backwash (CEB).
  • Long-term storage (> 7 days): Clean membranes using a CEB before disinfection. A 0.5% sodium metabisulfite solution can be used for disinfection. In both short and long-term storage, modules should remain filled with storage solution.
