Mechanical / Hydraulic

• Hydraulic membrane diameter: 5.2 mm
• Crossflow flow rate (*): 8.3 x v [m³/h] (where v is superficial velocity in m/s)
• Pressure-drop across module (laminar flow) (**): 1.2 x L0 x v [kPa] (where L0 is module length in m)
• Pressure-drop across module (turbulent flow) (**): 3.6 x L0 x v^(1.75) [kPa]

Storage

• New membrane modules: Store as supplied, in a dry, normally ventilated place, away from heat, ignition, and direct sunlight. Store between 0 and 40 °C. Do not subject to freezing temperatures.
• Used UF membranes: Must be stored wet at all times.
  • To avoid biological growth: Treat with a compatible biocide.
  • Short-term shutdowns: Daily flush with permeate quality water containing up to 2.0 ppm free available chlorine for 30 to 60 minutes may be adequate.
  • Long-term storage: Clean membranes before disinfection. A 1% sodium metabisulfite solution can be used for disinfection.
  • In either situation, modules should be stored hydraulically filled.
