Aerators, in those places we cannot see

2022-12-12 13:38

With the increasing industrialization in our country, various industrial and domestic wastewater flows into major rivers, turning the once clean, mirror-like water into dirty, foul-smelling water. People, who once could swim in the river with peace of mind, now dare not easily enter the water for fear of infection and various diseases. Indeed, this wastewater is extremely harmful to society and causes severe environmental pollution. Therefore, when industrial development reached a certain stage, the country promoted wastewater treatment plans. Government funds invested in water resources are used to treat wastewater in major cities. Finally, through persistent efforts, the original foul-smelling water flows through the self-flow of the water plant and becomes clear again when released.


Aerators have a simple structure, saving energy and efficiently utilizing oxygen. They are more common in the oxygenation equipment for urban wastewater and organic industrial wastewater treatment systems. Aerators developed in the 1980s produce extremely small bubbles and are highly corrosion-resistant. In summary, we should observe things from two perspectives, as everything has advantages and disadvantages. Industrial development has brought earth-shattering changes to people's lives, but it has also brought many problems, including industrial wastewater. Failure to treat wastewater promptly may endanger human life and health. Therefore, the emergence and application of aerators are crucial.


It is well known that untreated or improperly treated wastewater can easily become a threatening disaster, affecting people's normal social life and health. Most industrial production enterprises take the prevention of industrial wastewater as their starting point, supporting the research and development of wastewater treatment equipment and investing a large amount of funds and manpower. After long-term research and practice, aerators have begun to appear on the market. Industry insiders believe that aerators are experts in the field of wastewater treatment, bringing new hope to wastewater treatment. Due to the different membrane materials of various aerators, their application ranges are also very different. Before purchasing, be sure to clarify the wastewater treatment object. Aerators using EPDM rubber materials can only be used for municipal wastewater treatment. If low-plasticity EPDM rubber is used instead, they can be used not only for the production and processing of various foods but also for the discharge of wastewater during beverage production.

Practical application of IC tower in food processing wastewater treatment

Wastewater from the food processing industry contains a large amount of organic matter, suspended solids, and oils. Traditional treatment methods often face problems such as high energy consumption and long processing cycles. The IC tower (internal circulation anaerobic reactor), with its unique internal circulation structure and three-phase separation system, demonstrates technical adaptability in treating high-concentration organic wastewater. The core advantage of the IC tower lies in its internal circulation mechanism. Through the fluid movement of the internal rising and falling pipes, it achieves thorough mixing of sludge and wastewater, improving biodegradation efficiency. In food wastewater treatment, the IC tower can adapt to influent conditions with a wide range of COD concentrations, especially suitable for the dairy, meat processing, and brewing industries. Practice has shown that when treating oily wastewater, the IC tower can stably achieve a COD removal rate that meets emission standards by reasonably controlling the hydraulic retention time and organic load. In an actual engineering case, a large seasoning production enterprise used the IC tower as a pretreatment unit. The influent COD concentration ranged from 8000-12000mg/L, and after treatment by the IC tower, it was reduced to below 1500mg/L, significantly reducing the burden on the subsequent aerobic treatment unit. The operating data shows that the biogas yield of the IC tower is stable and can be used for energy recovery, further reducing treatment costs.

The effectiveness of IC tower in treating high-concentration organic wastewater

The IC tower (internal circulation anaerobic reactor) is an important piece of equipment in modern wastewater treatment, demonstrating significant technical characteristics in treating high-concentration organic wastewater. Its unique internal circulation system enhances the contact efficiency between sludge and wastewater, making the organic matter degradation process more thorough and showing clear adaptability in treating industrial wastewater with a COD concentration exceeding 3000 mg/L. The treatment effect of this technology is mainly reflected in two dimensions: organic matter removal rate and biogas production. Actual operating data shows that in wastewater treatment for industries such as brewing and food processing, the IC tower usually maintains a high COD removal rate. The granular sludge formed inside the reactor has good settling performance, ensuring the stability of system operation. When the temperature is controlled around 35℃, the microbial activity reaches an optimal state, and the treatment effect is relatively ideal. In the process of treating high-concentration organic wastewater, the volumetric loading capacity of the IC tower is a key indicator that distinguishes it from traditional anaerobic processes. Due to its multi-stage reaction zone design and internal circulation flow pattern, the equipment can withstand high organic load shocks. Pharmaceutical wastewater treatment cases show that the system can still maintain stable operation when the influent COD fluctuates between 5000-8000 mg/L.

Why are IC towers considered the "quality gatekeepers" of semiconductor packaging and testing plants?

In the back-end process of semiconductor manufacturing, the IC handler (integrated circuit testing and sorting equipment) plays a core role in verifying chip functions and screening for quality. Its working principle is to use a precision robotic arm to send wafers or packaged chips to the testing station, and use the probe card and tester to complete the electrical parameter measurement. Then, according to the test results, it automatically sorts out qualified products and defective products. This integrated "test-judgment-sorting" process makes it a decisive link in the quality control before the chip leaves the factory. From a technical perspective, the gatekeeping role of the IC handler is reflected in three dimensions: First, the contact testing scheme can simulate the actual working state of the chip and detect physical defects such as open circuits, short circuits, and leakage; second, the multi-station parallel testing architecture achieves the screening capacity of thousands of chips per unit time, matching the production capacity needs of the packaging and testing factory; more importantly, its test data is directly related to the yield statistics of the chip, providing key evidence for process improvement. Current mainstream equipment supports environmental temperature testing from -40℃ to 150℃, covering the reliability verification needs of different application scenarios such as consumer electronics and automotive electronics. In industrial practice, the testing standards of IC handlers are often more stringent than the terminal application conditions. Taking the case of a major packaging and testing factory as an example
