Selection Recommendations from 2023 Asian Games City Disc Diffuser Suppliers

Discs Diffusers are an essential component in aeration systems used in various water treatment applications such as wastewater treatment, aquaculture, and pond aeration. The selection of high-quality diffuser discs is crucial to achieving optimum aeration performance and reducing maintenance costs. In this article, we will discuss how to distinguish high-quality discs diffuser from low-quality ones.

How To Distinguish High-quality Disc Diffusers From Low-quality Ones?

1. About Disc Diffuser Material

The quality of disc diffusers is highly dependent on the material used to manufacture them. Common materials include rubber, silicone, polyurethane, and EPDM. EPDM Disc diffusers are the most commonly used due to their excellent aging resistance, UV resistance, and corrosion resistance. Therefore, when selecting disc diffusers, it is essential to choose those made of high-quality materials that can In the process of treating wastewater withstand harsh environments and have a longer lifespan. Good membrane skin, its tear strength can be improved to more than 35KN/m, good material can have high strength and high resilience and at the same time has good tear resistance. 

2. Disc Diffuser Hole Size and Spacing

.
The aperture and spacing of the aeration disc are important details to consider when choosing a high-quality aeration system, as they have a significant impact on the aeration performance and efficiency.

Firstly, the size of the aperture directly affects the aeration efficiency of the disc diffuser. The smaller the aperture, the better the aeration effect, as it can generate more bubbles at more locations, thereby increasing the aeration area and the amount of dissolved oxygen in the water. However, a too-small aperture can also increase resistance and the risk of blockage, as small holes are easily obstructed by suspended particles.

Secondly, the spacing between apertures is also a factor to consider. The smaller the spacing, the higher the aeration efficiency of the disc, as it can generate more bubbles on a larger aeration area. However, too-small spacing can also cause the aeration disc diffuser to become easily blocked, as suspended particles can more easily enter the small apertures and clog the holes.

Therefore, when choosing an aeration disc, it is necessary to consider the ventilation requirements of the system and the water quality to determine the most suitable aperture and spacing. Generally, for ordinary ponds and aquaculture applications, aeration discs with apertures between 2-5mm and spacing between 1-2cm are most commonly used. For wastewater treatment applications, the aperture and spacing may require more precise adjustments and selection.

3. Aeration Rate That Cannot Be Ignored

The airflow rate is an important indicator to measure the performance of an aeration disc. It represents the volume of gas that the aeration disc can inject into the water per unit of time. The higher the airflow rate of the aeration disc, the higher the oxidation efficiency of the aeration system, which means that it can increase the dissolved oxygen content in the water and promote the growth and health of aquatic organisms.

The airflow rate is influenced by multiple factors, including the aperture and spacing of the aeration disc, the material, the working pressure, etc. The aperture and spacing are the most critical factors as they directly affect the aeration area and the generation of bubbles. Material is also important, as different materials can have different effects on gas distribution and diffusion. The working pressure can also affect the airflow rate, as it affects the gas flow velocity and pressure, thereby affecting the generation and distribution of bubbles. To ensure that the aeration disc has a high airflow rate, it is necessary to choose a high-quality aeration disc. High-quality aeration discs usually have excellent material, precise processing technology, and high-quality apertures and spacing. In addition, it is also necessary to pay attention to the working pressure and airflow rate of the aeration disc to ensure that it can meet the requirements of specific applications.

4. About Durability

Durability is an essential factor to consider when selecting a disc diffuser. The lifespan of diffuser discs is dependent on the material, design, and maintenance practices. High-quality diffuser discs are designed to withstand harsh environments and have a longer lifespan, reducing the frequency of replacement and maintenance， more efficient in the use of wastewater treatment and aquaculture

Based on the above information, to choose an aeration disk believe that I can help you choose a high-quality aeration disk. Let you no longer worry about poor ventilation, poor durability, high noise, cleaning difficulties, etc.
