If the sludge is found white during operation

- Jun 27, 2019-


Lack of nutrition, filamentous fungi or sessile ciliates multiply, poor growth of bacterial micelles;

The PH value is high or too low, causing a large amount of filamentous bacteria to grow, the sludge is loose, and the volume is too large.


Adjust the influent load according to the nutrient ratio, and increase the amount of ammonia nitrogen to maintain the color of the sludge for several days;

Adjust the pH value of the influent water to maintain the pH value of the aeration tank between 6 and 8. Maintain the pH range for a long time to effectively prevent sludge expansion.
