R-100 1.5 MF

Summary

Product identification

The Pentair X-Flow R-100 is a microfiltration membrane module, specifically the 6” R-100 RVS module and R-100 RVS insert. It is a stainless steel module designed for the filtration and/or clarification of aqueous solutions and beverages such as wine, juice, or cider.

The mode of operation is feed and bleed in crossflow mode with regular backwash.

Process Characteristics

(Based on water at 20 °C, superficial velocity (v) in m/s)

• For 1.5 mm Membrane Diameter:

  • Crossflow flow rate: 14.8 x v m³/h
  • Pressure-drop across module at 1 m/s: 7 kPa
  • Pressure-drop across module at 2 m/s: 24 kPa

Operating limits

• Max. system pressure:
  • 1000 kPa at 20 °C
  • 600 kPa at 65 °C
• Max. transmembrane pressure:
  • 300 kPa at 0-50 °C
  • 200 kPa at 50-65 °C
• Max. backflush pressure:
  • 200 kPa at 0-30 °C
  • 150 kPa at 30-40 °C
  • 100 kPa at 40-65 °C
• Max. temperature: 65 °C

Final maximum operating limits are determined by the lowest values of the membrane and element pressure and temperature specifications. To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreases. Do not exceed 65 °C process temperature. Bring the module or element back to ambient operating temperature slowly (typical value 2-3 °C/min). Failure to adhere to this guideline can result in irreparable damage.

Feed 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 a dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight.

• Storage temperature: 0 to 40 °C
• Relative humidity: 20 to 80 %
• Membrane modules should not be subjected to any freezing temperatures.

After use, MF membranes can be dried and spontaneously re-wetted without the use of any wetting agents. To avoid biological growth during shutdowns or storage, wet membranes should be treated with a compatible biocide. The membrane is compatible with many common disinfecting agents or biocidal preservatives.

For short-term shutdowns, a daily flush with permeate quality water containing up to 2.0 ppm free available chlorine for 30 to 60 minutes may be adequate for bacteria control. In case of long-term storage, membranes should be cleaned before the disinfection step is carried out. For disinfection, a 1% sodium metabisulfite solution can be used.
