X-Flow-Compact-1-6 -5-2MM

Summary

Product identification

• Product Name: X-FLOW COMPACT 1.6 - 5.2MM Ultrafiltration Membrane
• Article Code: 7271KPB99R
• Description: Hydrophilic tubular polyvinylidene fluoride membrane cast on a polyester carrier. Structure is asymmetric, with a mean pore size of 30 nm. Developed for use in large-scale processes for water purification, offering high performance and very good anti-fouling behavior. Membrane elements can be backflushed for efficient cleaning, resulting in a higher average product flux.

Hydraulic

• Membrane diameter: 5.2 mm
• Crossflow flow rate: 8.3 x v [m³/h], where v = superficial velocity in m/s
• Pressure-drop across module (laminar flow): 1.2 x L0 x v [kPa], where L0 = module length in m, v = superficial velocity in m/s
• Pressure-drop across module (turbulent flow): 3.6 x L0 x v¹·⁷⁵ [kPa], where L0 = module length in m, v = superficial velocity in m/s

Electrical

• 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.

Mechanical / hydraulic

• Backwash water should be free of particulates and should be of permeate quality or better.
• To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasing temperatures.
• Bring the module or element back to ambient operating temperature slowly (typical value 3 °C/min).

Materials of Construction

• Housing: PVC, drinking water quality
• Potting: EP resin
• Membrane:
  • Material composed of polyvinylidene fluoride
  • Carrier is a composite polyester woven/non woven

Weight Specifications

• Dry weight of membrane element: ca. 2 kg [4 lbs]
• Membrane element filled with water: ca. 5 kg [11 lbs]

Cleaning Chemical Resistance

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.

• NaOCl (active chlorine): 500 ppm max.
  • Typical 200 ppm, at ≤ 40 °C
  • Maximum 500 ppm
  • 250,000 ppm hours cumulative at 30 °C
• H₂O₂: 1000 ppm max.
• NaOH: pH ≤ 11
• Nitric acid: pH ≥ 1
• Phosphoric acid: pH ≥ 1
• EDTA: pH ≤ 11
• Citric acid
• Enzymatic compounds

General Solvent Resistance

• Acids, pH >2: +
• Bases, pH <11: +
• Organic esters, ketones, ethers: --
• Aliphatic alcohols: ++
• Aliphatic hydrocarbons: ++
• Halogenated hydrocarbons: ++
• Aromatic hydrocarbons: +
• Polar organic solvents: --
• Oils: ++

Storage

• New membrane modules can be stored as supplied.
• Store membrane modules in a dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight.
• Storage temperature: 0 to 40 °C.
• Membrane modules should not be subjected to any freezing temperatures.
• After use, UF membranes need to be stored wet at all times.
• To avoid biological growth during shutdowns or storage, wet membranes should be treated with a compatible biocide.
• 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 the disinfection step is carried out. A 1% sodium metabisulfite solution can be used for disinfection.
• In either situation, modules should be stored hydraulically filled.
