X-Flow-B-0125

Summary

Product identification

The B 0125 is described as an advanced filtration, classic ultrafiltration membrane.

• ARTICLE CODE: HD70600
• Membrane Type: Hydrophilic polysulfone tubular membrane cast on a composite polyester carrier
• Tubular Membrane Diameter: 14.4 mm
• Structure: Asymmetric
• Developed for use in a variety of ultrafiltration processes in industrial food and non-food applications.

Operating limits

• pH: 2 - 10 (at 25 °C)
• Chlorine exposure: 150000 ppm.h (at 25 °C)
• Temperature: 1 - 70 °C
• Transmembrane pressure: -20 .. + 1000 kPa

Performance Data

• Initial flux: 125 ± 25 l/m².h (at 100 kPa with RO-water at 25 °C)
• Molecular weight cutoff: 50 kDa (90% rejection on dextranes)

Membrane Composition

• Membrane material composed of hydrophilic polysulfone.
• Membrane carrier is a composite polyester woven/non-woven.

Applications

• Concentration of modified starch wastewater
• Manufacture of starch derivates
• Production of whey protein concentrates
• Highly economical direct conversion of sour skimmed milk into quark
• Concentration of whole milk for cheese production
• Cost effective water removal from whole egg, egg white, fermented egg white and rinsing water
• Enzyme concentration
• Clarification of fruit juices

Solvent Resistance

The resistance of the membrane to solvents strongly depends on actual process conditions; indications are guidelines only.

• Acids, pH > 2: Compatible (+)
• Bases, pH < 11: Compatible (+)
• Organic esters, ketones, ethers: Not compatible (--)
• Aliphatic alcohols: Compatible (+)
• Aliphatic hydrocarbons: Compatible (+)
• Halogenated hydrocarbons: Not compatible (--)
• Aromatic hydrocarbons: Not compatible (--)
• Polar organic solvents: Not compatible (--)
• Oils: Compatible (+)

Cleaning

It is recommended to keep the pH between 1 and 11 and not to exceed a temperature of 40 °C during cleaning and/or disinfection.

• Chemical Cleaning Agents:
  • NaOCl (active chlorine): 500 ppm max.
  • H₂O₂: 1000 ppm max.
  • NaOH: pH ≤ 11 max.
  • Nitric acid: pH ≥ 1
  • Phosphoric acid: pH ≥ 1
  • EDTA: pH ≤ 11
  • Sodium tri-phosphate
  • Citric acid
  • Enzymatic compounds

Storage

• New membrane modules:
  • Store as supplied 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.
• Used UF membranes:
  • Must be stored wet at all times.
  • 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.
  • For long-term storage, membranes should be cleaned before disinfection. A 1% sodium metabisulfite solution can be used for disinfection.
  • In either situation, modules should be stored hydraulically filled.
