Disc Air Diffuser
Product Description：
Disc Air Diffuser 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 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 (micrometre 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 an 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.

How tube diffuser works
Tube diffusers work by uniformly dispersing a gas (usually air) into a liquid and are commonly used in water treatment and wastewater treatment. Here is a detailed explanation of how a Tube diffuser works:
Gas supply: First, gas (usually compressed air) is delivered to the Tube diffusers through a piping system. These pipes are typically connected to a central gas supply system that controls the flow and distribution of gas through valves and controls.
Tube Diffuser Construction: Tube diffusers are typically made from long tubes that contain tiny holes or micropores inside. These micropores are usually located at the bottom of the pipe, but are sometimes located on the sides.
Gas release: Gas is released through micropores in the pipe of the Tube diffuser and enters the liquid (such as water or wastewater) connected to the pipe. These micro-holes are carefully designed to ensure that the gas is ejected in an even manner.
Gas-liquid mixing: When gas is released from the micropores, it enters the liquid in the form of small bubbles. These small bubbles rise in the liquid while exchanging substances with contaminants, microorganisms or other dissolved gases in the liquid. This uniform dispersion of gas and the small size of the bubbles help improve gas-liquid transfer efficiency.
Mass transfer process: One of the key roles of tube diffusers is to facilitate mass transfer between bubbles and liquid. In water treatment applications, this often involves the diffusion of oxygen from air bubbles into the water to promote biodegradation or remove contaminants from the wastewater.
Improve water oxygenation: Tube diffusers are often used to increase the solubility of oxygen in water. This is important for wastewater treatment and water aeration, as oxygen is a key factor required by microorganisms to degrade pollutants.
In general, Tube diffusers help improve the quality of water bodies, improve wastewater treatment efficiency, and maintain ecological balance in ponds, lakes and other water bodies by evenly dispersing gas into liquids, thus promoting gas-liquid transfer and oxygen dissolution. . The efficiency and performance of these systems are often affected by design, operation and maintenance.
