A study was conducted using an 840 gallon test tank to evaluate the impact of carrier media on standard oxygen transfer efficiency in clean water (SOTEcw), using coarse and fine bubble air diffusers used in Integrated Fixed-Film Activated Sludge and Mixed Bed Biofilm Reactor systems. Fine bubble diffusers, or those that produce a large amount of very small air bubbles, first began to become popular in the 1980s, as they had a much higher efficiency than coarse bubble diffusers. Fine bubble diffusers generally feature a membrane that allows airflow to pass from the piping system on the floor of the tank through the body of ...
AirRex® can be retrofitted into basins equipped with fine bubble aeration to increase efficiency and yield a reasonable payback as well as older, coarse bubble installations. New installations will be the lowest cost high efficiency diffuser system available. The AirRex® piping system is optionally equipped with a 3/4″NPT or BSP female thread.

This product includes a single 9″ fine bubble membrane diffuser disc and a heavy duty base. Key Benefits: Fine bubble diffusion is the … During their years of testing all types of air diffusers for coarse and medium bubble aeration of activated sludge, they worked to develop a truly non-clogging diffuser. They found that the only way to eliminate clogging completely is to locate the metering orifice above the liquid level under aeration, and to use the principle of hydraulic shear to generate small air bubbles, rather than submerged orifices or pores.
These are the most commonly used diffuser in water treatment. Available in fine or coarse bubbles, from 3 – 20 inch and various NPT connection types, makes them easy to operate.
