RX-300 1.5UFC

Summary

Product identification

• Product Name: X-flow RX-300 1.5UFC Ultrafiltration Membrane
• Article Code: 1051BB495A
• Type: Ultrafiltration pilot module
• Applications: Production of process and potable water; filtration of surface water, potable water, and WWTP effluent.
• 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
• Element Specifications:
  • Membrane diameter: 1.5 mm [59 mil]
  • Membrane area: 0.04 m² [0.46 ft²]
  • Element length L0: 300 mm [11.8 Inch]
  • Element outer diameter: 23.9 mm [0.94 Inch]

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. Trans-membrane 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]
• Temperature Change Caution: To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreases. Do not exceed 60 °C process temperature. Bring the module or element back to ambient operating temperature slowly (typical value 1 °C/min). Failure to adhere to this guideline can result in irreparable damage. Final maximum operating limits are determined by the lowest values of the membrane and element pressure and temperature specifications.

Mechanical / hydraulic

• Membrane Characteristics:
  • Membrane diameter: 1.5 mm [59 mil]
  • Flow rate (*): 0.25 x v [0.33 x v] (where v = superficial velocity in m/s [ft/s])
  • Pressure-drop across module at 1 m/s: 4 kPa [0.6 psi]
  • Pressure-drop across module at 2 m/s: 17 kPa [2.5 psi]
• Backwash Water Quality: Backwash water should be free of particulates and should be of permeate quality or better.
• Backwash Pumps: Backwash pumps should preferably be made of non-corroding materials, e.g., plastic or stainless steel.
• Compressed Air for Backwash: If compressed air is used to pressurize the backwash water, do not allow a two-phase air/water mixture to enter the element.

Storage

• New Modules: Can be stored as supplied in the original packaging.
• Preservation Solution (as supplied): Aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%).
• Storage Conditions: Store in a dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight. Store between 0 and 40 °C. Membrane modules should not be subjected to any freezing temperatures.
• Shelf Life: Maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership. After the maximum period of 6 months, all warranties are null and void unless otherwise agreed in writing.
• After Use: UF membrane modules need to be stored wet at all times.
• Short-Term Shutdowns (1 – 7 days):
  • Before the shutdown period, modules must be cleaned by a standard Chemical Enhanced Backwash (CEB).
  • A daily backwash with UF permeate quality water for 30 seconds at 250 lmh should be adequate for bacteria control.
• Long-Term Storage (> 7 days):
  • Membranes should be cleaned using a CEB before the disinfection step is carried out.
  • For disinfection, a 0.5% sodium metabisulfite solution can be used.
• General Storage (after use): In both short and long-term storage situations, the modules should remain filled with storage solution.
