Disc Air 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 that help break down the waste so that it can settle in the secondary clarifiers or be filtered by membranes. A fine bubble diffuser is commonly manufactured in various forms: tube, disc, plate, and dome. The importance of achieving ever smaller bubble sizes has been a hotly debated subject in the industry as ultra-fine bubbles (micrometer size) are generally perceived to rise too slowly and provide too little "pumpage" to provide adequate mixing of sewage in an aeration tank. Along with surface aerators, fine bubble aeration is one of the most often selected solutions for wastewater lagoon treatment. Installed at the bottom of the lagoon, fine bubble aerators release tiny bubbles that slowly rise to the surface of the water. These thousands of tiny bubbles collectively have a very large surface area. As a result, they can efficiently and effectively transfer oxygen to the entirety of the water column.
Cons of Tube Diffusers:
Boasting a Standard Aeration Efficiency (SAE) of 4–7 lbs O2/hr/hp-wire, very few aeration technologies can compete with the fine bubble in terms of energy efficiency. In many cases, switching from alternative lagoon aeration technologies, such as surface aeration or coarse bubble aeration, can save anywhere from 40–60% (or more) on energy costs. Similar to other industries, wastewater treatment must advance with the times. With the current worldwide initiative to “Go Green,” and to find energy-efficient, environmentally friendly solutions, fine bubble aeration fits in perfectly. There is some necessary maintenance, such as periodic cleaning, but maintenance is a part of any wastewater lagoon aeration system. Its energy efficiency and ability to improve dissolved oxygen levels tend to outweigh the negatives. For this reason, we’ve recently seen a worldwide trend of wastewater treatment facilities switching from surface aeration (and other wastewater lagoon treatment alternatives) to fine bubble aeration.
