Product Description

Product Description:

1. Aeration system composition: the pool aerator system consists of disc-type microporous silicone rubber aerator, special rubber sealing adapter, air supply branch pipe, air distribution pipe, DN20 drainage pipe system and pipe adjustable height support frame (stainless steel) and other components.

2. Silicone rubber diaphragm air distribution performance: to ensure that the airflow is uniformly distributed over its entire surface, the number of holes in the silicone rubber diaphragm and the size of the hole diameter is fully in line with the requirements of oxygenation performance.

3. Aerator appearance: microporous silicone rubber membrane appearance smooth, flat, no impurities, no bubbles and cracks.

4. Interchangeability: The aerator is generally connected by R3/4" external threads, which is a universal interface with good interchangeability.

The DUBHE Fine Bubble Disc Diffuser , model number DUDS, is an advanced wastewater treatment component designed for a variety of applications. Manufactured in China from high-quality EPDM material, this diffuser is engineered to provide efficient aeration in wastewater treatment systems. With an air consumption rate of 0.2-0.6m3/min and equipped with 3500 to 8000 holes, it creates an abundance of fine bubbles, leading to a Standard Oxygen Transfer Efficiency (SOTE) ranging from 22% to 59%.

One of the primary application scenarios for the DUBHE Fine Bubble Disc Diffuser is in municipal wastewater treatment plants. Here, the disc diffuser is utilized in aeration tanks to enhance the biological treatment phase by introducing oxygen that is essential for the growth and activity of microorganisms, which break down organic pollutants. The fine bubble aeration process is highly efficient, resulting in energy savings and improved effluent quality.

Another key application for the DUBHE Fine Bubble Disc Diffuser is in industrial wastewater treatment facilities. Industries such as pharmaceuticals, food and beverage, and chemical manufacturing can leverage the high SOTE of the DUDS model to achieve stringent discharge standards while maintaining operational efficiency. The disc shape of the diffuser allows for a uniform distribution of bubbles, providing optimal contact between the wastewater and the microorganisms.

Aquaculture is an additional sector where the DUDS model finds its application. The fine bubbles produced help maintain adequate dissolved oxygen levels in the water, which is critical for the health and growth of fish and other aquatic species. The robust EPDM material ensures that the diffuser can withstand various aquatic environments, making it suitable for both freshwater and marine applications.

Furthermore, the DUBHE Fine Bubble Disc Diffuser is also ideal for use in experimental and pilot-scale wastewater treatment systems. Research institutions and development projects can benefit from the precise control of aeration and the high oxygen transfer efficiency, facilitating the study and development of new wastewater treatment processes and technologies.

In summary, the versatility, durability, and efficiency of the DUBHE Fine Bubble Disc Diffuser make it an excellent choice for a wide range of aeration applications, from municipal and industrial wastewater treatment to aquaculture and research facilities. Its superior performance and reliability are assets in scenarios demanding high-quality aeration and oxygenation.
