Tube Membrane Diffuser

Tubular membrane diffuser for wastewater aeration, PP body, EPDM, PU or silicone membrane

Tubular fine-bubble membrane diffuser with polypropylene body, available with EPDM, PU or silicone membrane, suitable for intermittent operation.

Properties

  • available with EPDM, PU or silicone membrane
  • suitable for intermittent operation
  • usually mounted in pairs on square or round stainless steel pipes in the aeration basin
  • air is fed through a 3/4" connector via the aeration grid into the distribution chambers and from there under the membrane
  • the perforation opens when air is supplied; air leaves the diffuser as small bubbles into the wastewater
  • when the air is switched off, the water pressure presses the membrane onto the air hole and closes the aeration system
