How to quickly troubleshoot wastewater screens for MBBR system

To quickly troubleshoot wastewater screens for the MBBR system, you can do it one by one from the following aspects:

1. Observe the operating phenomenon
Check whether there is abnormal noise when the screen is running. If there is a harsh friction sound, it may be that the screen and the transmission parts are loose or worn; observe the running speed of the screen. If the speed slows down or stops significantly, it may be a motor failure, the transmission belt slips, or the screen is stuck by a large amount of impurities.

2. Check the blockage
Check whether there are a lot of impurities accumulated on the surface of the screen. If there are too many impurities, the screen may be blocked and affect the water flow efficiency; check the liquid level difference before and after the screen. If the liquid level difference is too large, it means that the screen is blocked from passing water, and it is necessary to further clean the impurities or check whether the screen is damaged or deformed.

3. Check the electrical system
Check the running current of the motor. If the current is too large or too small, it may indicate motor failure or abnormal load; check whether the circuit breaker, contactor, and other components in the electrical control cabinet are working properly, whether there are problems such as contact burnout and loose circuit; check whether the electronic components such as sensors and controllers transmit signals normally to ensure that the automatic control system can accurately feedback the operation status of the screen.

4. Check mechanical parts
Check whether the transmission belts, chains, and other transmission parts are loose or broken, and adjust or replace them in time; check whether the rotating parts such as bearings and sleeves are worn or lack oil, resulting in poor operation; check whether the screen frame is stable, deformed or cracked. If the frame is damaged, it may affect the normal operation and screening effect of the screen.

5. Analyze the impact of water quality
Compare the changes in the quality of the incoming water. If the impurity content and particle size in the sewage suddenly change, it may exceed the processing capacity of the screen and cause failure; check the pH of the sewage. If the corrosiveness of the water quality increases, it may accelerate the damage to the screen material. It is necessary to take anti-corrosion measures or replace the corrosion-resistant screen in time.
