The choice of a fine bubble diffuser – Disc Diffuser – Tube Diffuser Panel or diffuser?
Diffusers are available in many ways, including discos, tubes, square and rectangular panels, and various materials, including EPDM elastomers and as porous media such as aluminum oxide, porcelain, or HDPE. Many books and articles have been written about the differences between these media.
However, there are still many questions about the superiority or application disk vs vs tube panel. Many of the manufacturers in the business of making multiple types of diffuser, although they tend to encourage and promote more than others, usually for commercial reasons (Which have a greater margin in a product) or for reasons of product differentiation (when specified by a customer or an engineer, is hard to find "same" competitors).
Many tests of efficiency of oxygen transfer have been conducted over the years in each type of diffuser (Some of which are published in Handbuch ATV), however product development is dynamic, and what was tested in mid-1980 can not be applied today to the modern disks, tubes and panels.
There are some common sense principles to follow, regardless of the evolution of technology.
In a stainless steel retrieval system costly, diffuser that can handle most of the air with stainless infrastructure will at least be an attractive option. Normally the tube diffusers are recovering systems for this reason.
In a fixed system where the pipes are bolted to the floor, and longevity and low maintenance are required, disc diffusers are popular tubes.
On failure, it is important (ie catastrophic disc diffusers vs slow) may take priority over the tubes. tube diffusers are have a large air hole size, therefore in case of a rupture of the membrane or the lack of restraint, a large volume of air can escape from that hole, starve the rest of the system.
The deeper the tank, broadcasters benefit less from the panel to offer in terms of efficiency. The panels are designed to produce very fine bubbles. In a shallow tank, this is a benefit, albeit a costly from panel systems often carry a hefty price tag due to the amount of equipment required to purchase and install. However, in a deep tank, so much of the oxygen is transferred at the time that the bubble has risen 15 feet that the bubble is said to be without oxygen, therefore, the benefit disappears. You should also take account of the drop panel of broadcasters, since what gain in terms of efficiency of small bubbles often lost in the additional power needed to overcome the pressure of the high back of the membranes of the panel.
Whatever type of speaker, one must consider PTFE-coated membrane diffusers, which can extend the life of the membrane and also reduce surface contamination as well.
