If the sludge is found white during operation

- Jun 27, 2019-

cause:


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.


  Solution:


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.
