Product Overview

CM Aquatechnik supplies fine-bubble membrane disc and tube diffusers for biological aeration in activated sludge, MBR, and SBR treatment tanks. EPDM and polyurethane membrane diffusers achieve oxygen transfer efficiency (OTE) of 6–8% per metre submergence, typically 20–35% standard oxygen transfer efficiency (SOTE) — significantly higher than coarse-bubble systems.

Key Features

  • EPDM membrane achieves > 99% bubble uniformity for efficient oxygen transfer
  • Patented non-return check valve prevents sludge backflow when air is off
  • Polyurethane membranes for oily or greasy wastewater service
  • Drop-in replacement for FLEXAZÓN, SANITAIRE, and other major brands
  • Anchor saddles and diffuser holders in PP, HDPE, or SS316L
  • Full air distribution piping design and supply available

Applications

Activated sludge aeration tanks MBR bioreactor aeration SBR (sequencing batch reactor) aeration Nitrification and denitrification tanks Sludge aerobic digestion Lagoon destratification
