Chemically Resistant Membranes

 

Sterlitech offers membranes that exhibit high resistance under chemically harsh conditions. These membranes are ideal for applications such as:

  • Organic Solvent Nanofiltration (OSN)
  • Membrane distillation
  • Pervaporation
  • Solvent recycling
  • Electrolysis
  • Treatment of corrosive solutions (acid, caustic, etc.)
  • Low protein binding filtration
  • Fuel cell or battery separator applications
  • Metal and chemical industry applications
