In wastewater treatment, aeration types can generally be divided into two categories: air blower aeration and mechanical aeration. The air blower aeration system consists of an air blower, air diffusion devices (aerators), and a series of interconnected pipes. In this aeration system, the aerator plays a crucial role. The diaphragm-type microporous aerator (fine bubble aerator) is the most commonly used type. It has a high oxygen transfer rate and operational efficiency, but it has some drawbacks, such as the need for dust removal in the incoming air and the risk of clogging in the aerator’s pores. With the development of technology, continuous improvements have been made. Today’s diaphragm-type microporous aerators not only have high energy efficiency and good application effects, but also avoid clogging problems.

Aquasust, in response to market demand and to address wastewater treatment issues, continually optimizes the quality and technology of its aeration discs. The Aquasust aeration disc has many advantages, making it widely used in water treatment. Its unique “工” (gong) shape design is key to enhancing performance. From the perspective of diaphragm lifespan, this “工” shape effectively distributes tearing stress. When the aeration disc operates, the gas impact generates stress, and this structure helps the stress distribute evenly, preventing localized stress concentration that could damage the diaphragm. This greatly improves the tearing strength, extending the diaphragm’s life, reducing the frequency of replacements, and lowering maintenance costs.
The Aquasust aeration disc uses a uniquely developed aeration membrane, which offers excellent durability, significantly extending the overall lifespan of the aeration disc. In practical applications, this reduces the manpower and material costs associated with frequent membrane replacements, ensuring stable long-term operation.

The membrane is particularly outstanding in resisting scaling and calcium deposits. In complex water environments, it effectively prevents the adhesion of impurities and calcium scales, maintaining good ventilation performance and avoiding aeration efficiency reduction caused by scaling, thus ensuring stable equipment operation.
Chemically, the Aquasust aeration disc membrane exhibits exceptional resistance. It maintains stable physical and chemical properties, not deforming or corroding when exposed to strong acids, bases, oils, greases, and other chemicals. This guarantees normal operation of the aeration disc. Moreover, the membrane also performs well in environments containing hydrocarbons, fuels, and solvents, greatly expanding the aeration disc’s application scope. It can effectively meet the aeration needs of industrial wastewater treatment and special chemical processes, making it an ideal choice for wastewater treatment and similar applications.


In terms of pricing, the Aquasust aeration disc offers excellent cost-effectiveness, providing reliable performance at an affordable price. Even compared to well-known foreign brands, it stands out with its competitive pricing. In addition, Aquasust actively expands its after-sales system, offering timely technical support and maintenance services to ensure the stable operation of the equipment, providing users with peace of mind. It is a superior choice for applications such as wastewater treatment.
