RX-300 0.83UFC

Summary

Product identification

The X-FLOW RX300 0.83UFC is an ultrafiltration pilot module, used for the production of process and potable water.

• Article Code: 1051BL895A
• Typical Applications: 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

Mechanical / hydraulic

Element Specifications

• Membrane diameter: 0.83 mm [32.7 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]

Membrane Characteristics (Water 20 °C)

• Membrane diameter: 0.83 mm [32.7 mil]
• Flow rate (*): 0.27 x v [1.19 x v] (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]

Operating limits

• Max. system pressure:
  • at 20 °C: 800 kPa [116 psi]
  • at 40 °C: 600 kPa [86 psi]
  • at 60 °C: 400 kPa [58 psi]
• Max. transmembrane pressure:
  • at 0-30 °C: 300 kPa [43 psi]
  • at 30-60 °C: 200 kPa [29 psi]
• Max. backflush pressure:
  • at 0-30 °C: 300 kPa [43 psi]
  • at 30-60 °C: 150 kPa [21.5 psi]
• Max. temperature: 60 °C [140 °F]

Process Characteristics (Water 20 °C) Guidelines:

• To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasing temperatures.
• 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.

Product water

• Backwash water should be free of particulates and should 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 the backwash water, do not allow a two-phase air/water mixture to enter the element.

Storage

• New membrane modules: Can be stored as supplied in the original packaging.
• Preservation solution: The membrane 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.
• Freezing: Membrane modules should not be subjected to any freezing temperatures.
• Shelf life: A maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership. After this period, all warrantees 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): A daily backwash with UF permeate quality water for 30 seconds at 240 lmh should be adequate for bacteria control. Before the shutdown period, modules must be cleaned by a standard Chemical Enhanced Backwash (CEB).
• Long-term storage (> 7 days): Membranes should be disinfected after a CEB. A 0.5% sodium metabisulfite solution can be used for disinfection.
• In both short and long-term storage situations, the modules should remain filled with storage solution.
