Fine Bubble Diffuser

Aporous Tube or Disc or Strip through which air is forced and divided into minute bubbles for diffusion in the water thereby increasing the oxygen quantity in the water or the fluid. This is advanced in the view of better performance, high oxygen transfer efficiency, low power consumption and cost effective due to low maintenance.


Fine bubble membrane diffuser generally delivers greatest energy saving When they can be distributed in more uniform distribution on the floor of the basin. In diffused type of aeration system the size of the bubble play a major role. Bubble diameter can critically affect proces efficiency because it determines the surface area of the bubbles. Surprisingly, the most important factor has been found to be the ratio of the surface energy of the diffuser material at the water interface to the surface tension of the liquid. The higher the ratio, the smaller the bubbles.


Structure :

  • Membrane with micro slits to prevent clogging and back flow with flexibility of air volume.
