X-Flow-RX300-1-5UFC

Summary

Product identification

The RX-300 1.5UFC is an ultrafiltration pilot module designed for the production of process and potable water.

Typical applications include:

• Filtration of surface water
• Filtration of potable water
• Filtration of WWTP (Wastewater Treatment Plant) effluent

Mode of operation is feed-and-bleed with a minor crossflow or dead-end mode with regular backwash (permeate only) and chemically enhanced backwash.

• Article Code: 1051BB495A

Materials of Construction

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

Mechanical / Hydraulic

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]

Membrane Characteristics (Water at 20 °C)

• Membrane diameter: 1.5 mm [59 mil]
• Flow rate (*): 0.25 x v m³/h [0.33 x v gpm] (where v is 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 Requirements

• 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 backwash water, do not allow a two-phase air/water mixture to enter the element.

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]

Operational Guidelines

• 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).
• Final maximum operating limits are determined by the lowest values of the membrane and element pressure and temperature specifications.

Storage

New Membrane Modules

• Can be stored as supplied in the original packaging.
• Contain an aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%).
• Should be stored in a dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight.
• Store between 0 and 40 °C.
• Should not be subjected to any freezing temperatures.
• Shelf life is a maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership for X-Flow BV to the Client. After 6 months, all warranties are null and void unless otherwise agreed.

After Use

• UF membrane modules need to be stored wet at all times.
• To avoid biological growth during shutdowns or storage, wet membranes can be treated with a compatible biocide.
• The membrane is compatible with many common disinfecting agents or biocidal preservatives.
• For short-term shutdowns (1–7 days), a daily backwash with UF permeate quality water for 30 seconds at 250 lmh should be adequate for bacteria control. Before the shutdown, modules must be cleaned by a standard Chemical Enhanced Backwash (CEB).
• For 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, modules should remain filled with storage solution.
