General Solvent Resistance (Guidelines)

• Acids, pH >2: + (Resistant)
• Bases, pH <11: + (Resistant)
• Organic esters, ketones, ethers: -- (Not recommended)

Storage

• New membrane modules: Can be stored as supplied in a dry, normally ventilated place, away from sources of heat, ignition, and direct sunlight. Store between 0 and 40 °C. Do not subject to freezing temperatures.
• After use: UF membranes need to be stored wet at all times.
• Biological growth prevention: Treat wet membranes 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.
  • Long-term storage: Clean membranes before disinfection. A 1% sodium metabisulfite solution can be used for disinfection.
• In either post-use storage situation, modules should be stored hydraulically filled.
