Overview of Product Development

In the current sewage treatment process, aerators are widely used. They are not only used in large quantities, but also the core component of the sewage treatment process, directly affecting the operation quality and effluent quality of the sewage plant.

Given its importance in wastewater treatment, various types of aerators have been developed in the industry since their inception, with a trend towards diversification in material selection and working principles. Among them, the most widely used and currently the most mature technology is the disc membrane microporous aerator. It has the characteristics of small aeration bubbles, large gas-liquid area, uniform bubble diffusion, no pore blockage, and strong corrosion resistance, so it is widely used in water treatment projects in various industries.

Key points of development technology

During our years of use of aerators, our company has summarized the defects of various aerators based on customer feedback and our own experience. In cooperation with design institutes and universities, we have developed a new generation of WZZ-215 aerators.

It is designed with a slightly raised arched surface and is mainly made of ABS engineering plastic. The membrane has a special imported rubber (EPDM) with an anti adhesion surface, which is made through special processing. The membrane holes are selected from German imported CNC holes to ensure the quality and accuracy of the holes. The aerator is designed with six air supply slots on the main panel during oxygen aeration, allowing the incoming air to be buffered by a check valve and directly sent to the center of the aeration head to ensure that the membrane can be easily opened with low resistance at once. The membrane adopts ribbed locking mechanical assembly to ensure that the membrane never falls off. During air intake, the micro pores on the air film expand and open on their own to ensure the passage of air. When the aeration is stopped, the variable micropores on the air distribution film are in a closed state. Due to the self expansion and contraction of the variable micropores on the air distribution film, the phenomenon of blockage of the micropores passing through the aerator is avoided. Secondly, a patented rubber check valve device is installed on the chassis of the aerator to prevent the mixture of air and water from entering the gas distribution branch pipe when the pipeline system stops supplying gas, thus avoiding blockage caused by the mixture entering the branch pipe. The air does not require special filtration, and intermittent aeration does not cause blockages. Significant technological improvements have been made to address the common issues of blown air membranes, torn membranes, inability to open membranes, or membrane blockages in variable microporous aerators. These technological reforms have enabled them to operate for a long time without the need for maintenance, making them an excellent product of the new generation.
