12 inch High oxygen Aerator Membrane Fine bubble Disc Diffuser
12 inch fine bubble diffuser is a subsurface form of diffusion in which air is introduced in the form of very small bubbles to aid or enhance the treatment of wastewater. It is used to dissolve oxygen into wastewater so that the microorganisms can utilize it while they break down organic material.
