For fine bubble diffusers, the common standard recommended for effluent air quality is milligrams or less of dirt per thousand cubic feet of air. In addition to particulates in the air, diffusers can be clogged externally by fine sand in the tank liquor, excessive calcium carbonate hardness in the water supply.

Diffused aeration systems can be classified into three categories: Porous (fine bubble) diffusers: Fine pore diffusers are mounted or screwed into the diffuser header pipe (air manifold) that may run along the length or width of the tank or on a short manifold mounted on a movable pipe (lift pipe).

Fine bubble diffusers produce a plethora of very small air bubbles which rise slowly from the floor of a wastewater treatment plant or sewage treatment plant aeration tank and provide substantial and efficient mass transfer of oxygen to the water.

The oxygen, combined with the food source, sewage, allows the bacteria to produce enzymes which help break down the. Coarse bubble diffusers are a non-clog diffuser ideally suited for intermittent aeration systems and sewage streams that have had limited screening.

Air quality required for the coarse bubble diffuser is not as critical as for the fine bubble type. The EPCO Australia range of coarse bubble diffusers are extremely reliable under arduous.

For clean water aeration, the oxygen transfer efficiency provided by fine bubble diffusers usually exceeds that available from coarse bubble systems.

In wastewater, this may not always be the case. The design engineer and equipment vendor use a factor called alpha to adjust the clean water transfer efficiency to take into account the affects of.
