Product Description

Product Description

The Fine Bubble Disc Diffuser is a state-of-the-art aeration device designed to enhance the efficiency of wastewater treatment processes. This cutting-edge product is engineered to deliver a high oxygen transfer efficiency (OTE), with a Standard Oxygen Transfer Efficiency (SOTE) ranging from 22% to an impressive 59%. The Fine Bubble Disc Diffuser stands out in the market for its ability to significantly improve the dissolution of oxygen into wastewater, thereby facilitating the biological degradation of pollutants and enhancing the overall treatment process.

Specification

Applications

In a wastewater treatment plant, the Fine Bubble Disc Diffuser is installed in the aeration tank, where it releases a constant stream of small air bubbles. These bubbles rise to the surface, creating turbulence and increasing the contact between air and water. This allows for the transfer of oxygen from the air into the water, promoting the growth of beneficial bacteria that break down organic matter.
In an aquaculture facility, the Fine Bubble Disc Diffuser is used to provide oxygen to fish and other aquatic animals. The small bubbles created by the diffuser help to increase the dissolved oxygen levels in the water, creating a healthier environment for the aquatic life to thrive in.
In industrial processes, the Fine Bubble Disc Diffuser is used to aerate and mix liquids, such as in fermentation tanks or chemical reactors. It helps to improve the efficiency of the process by providing a constant supply of oxygen and promoting mixing and circulation. Overall, the Fine Bubble Disc Diffuser is a versatile and essential product that plays a crucial role in various applications. Its high-quality design and efficient performance make it a popular choice for aeration systems around the world.
