Application scenarios of coarse bubble diffuser for aeration tanks
Apr 19, 2025
1. Municipal sewage treatment plants
In large municipal sewage treatment plants, a huge amount of sewage needs to be treated every day. With its excellent stirring ability, coarse bubble diffuser for aeration tanks can ensure that the activated sludge and sewage are fully mixed. In the primary enhanced treatment stage, it can quickly increase the dissolved oxygen, help microorganisms decompose organic pollutants in sewage, and lay the foundation for subsequent deep treatment. Moreover, in the face of complex and diverse sewage water quality, its non-clogging characteristics ensure the stable operation of the equipment, reduce maintenance costs and downtime risks, and maintain the continuity of the sewage treatment process.
2. Industrial wastewater treatment
Food processing wastewater: The wastewater generated by food processing is rich in a large amount of organic debris and suspended matter. The strong stirring function of coarse bubble diffuser for aeration tanks can prevent these impurities from precipitating, while efficiently oxygenating, providing a suitable environment for microorganisms that degrade high-concentration organic matter. For example, in the treatment of meat processing wastewater, it can quickly decompose pollutants such as blood and grease to achieve standard discharge.
Papermaking wastewater: Papermaking wastewater contains difficult-to-degrade substances such as fiber and lignin, and the water quality and water volume fluctuate greatly. Coarse bubble diffuser for aeration tanks can adapt to this unstable working condition, continuously provide sufficient oxygen, promote the decomposition of complex pollutants by microorganisms, and prevent the accumulation of fiber and other substances in the aeration tank through strong stirring.

3. Aquaculture
In large-scale aquaculture ponds, sufficient dissolved oxygen is required to ensure the healthy growth of aquatic organisms such as fish. Coarse bubble diffuser for aeration tanks are easy to install and can be evenly arranged at the bottom of the pond. The larger bubbles it produces can quickly increase the dissolved oxygen in the water body, and at the same time stir the water flow, making the pond water temperature and dissolved oxygen distribution more even, creating a good living environment for aquatic organisms, preventing the occurrence of diseases, and improving aquaculture production and quality.
4. Landscape water restoration
Urban landscape lakes, rivers and other water bodies are prone to eutrophication, leading to algae breeding and water quality deterioration. Coarse bubble diffuser for aeration tanks can be installed at the bottom of the water body. Through aeration, it increases dissolved oxygen in the water, promotes the reproduction of aerobic microorganisms, decomposes organic matter in the water body, and inhibits excessive growth of algae. Its strong stirring effect can also break the stratification of the water body, improve water circulation, restore the ecological balance of the landscape water body, enhance the self-purification ability of the water body, and make the landscape water clearer and more beautiful.
