Selecting a Bubble Diffuser for Various Industrial Uses

When you are looking to buy a bubble diffuser for your sewage treatment or wastewater management

of some industry in particular, you need to be very particular in choosing your equipment for the same.

Out of the many choices available to you, your decision should be based on certain critical factors

pertaining to the specific requirements. Out of the many shapes, sizes, squares and rectangular panels

of bubble diffusers available, the differences in working of equipment should be clear to you when

buying.

Difference in working of bubble diffusers

The different materials with which the bubble diffusers are made, such as aluminum oxide, HDPE and

porcelain are put to different uses as explained by various books and papers written on this subject.

However, the question of whether disc diffuser is superior to tube or panel or vice versa has not been

settled yet. Nonetheless, you will find that the manufacturers mostly try to project one type of product

as superior to the other. The reason is purely commercial.

The ordinary manufacturers always look to make more profits and do not pay heed to fulfilling the

needs of the customers. This is mainly based on charging extra for a product that they manufacture for

which it is difficult for the customers to find a competitor of equal standing. The efficacy of a particular

bubble diffuser boils down to oxygen transfer efficiency. The reports published in the 1980s regarding

the use of disc, bubble or tube diffuser do not apply nowadays but some common sense factors hold

true still.

Common sense principles for choosing diffusers

If you are looking for diffusers in a retrievable system that comprises of expensive stainless steel

structures, choose one which is able to manage most volume of air with least bit of stainless

infrastructure. Thus, in this case, you should order tube diffusers.

In a fixed aeration system wherein the pipes are fastened to the floor, you should choose disc diffusers

over tube because of low maintenance costs and but still there is the promise of longevity.

In a failure mode, disc diffuser should be given the preference over tube because the latter possess a

larger air orifice. This allows for larger volume of air to escape in case of clamp failure or rupture of

membrane, thus protecting the rest of the system.

Choice of a bubble diffuser should be made after careful consideration of the factors mentioned above.
