Microporous aerator: pipe connection and installation methods

Release time:

2022-12-30 14:50

 

 

Microporous aerators, also known as multi-porous structure gas diffusion devices, are made using porous materials such as ceramsite sand and coarse porcelain, mixed with a suitable binder such as urea-formaldehyde resin, and then fired at high temperatures to form diffusion plates, external diffusion pipes, and external diffusion hoods.

The hydrolysis acidification tank equipment consists of a mechanical filter, air distribution pipelines, three-way valves, four-way valves, bends, controllers, connectors, and elimination devices.

The air distribution pipelines are arranged in a general annular layout. The mechanical filters are arranged according to the air supply volume and the density of the tank shape layout. The mechanical filters and air distribution pipelines are connected using G3/4 bolts. The base is a threaded mechanical filter with British threads. During installation, first fix the controller to the pool with expansion screws according to the required specifications, then fix the air distribution pipelines to the controller with hose clamps.

To prevent damage to the hydrolysis acidification tank equipment from other work such as electric arc welding flames and construction work (e.g., concrete lifting), install the mechanical filter after the construction work is completed and before adding water. To prevent gas leakage from the pipelines and connections, add water to a depth of about 10 cm above the mechanical filter for leak testing. Then, ventilate. If any gas leakage is found in the pipeline connections, clean it immediately, and then put it into formal use.

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
