With a low inflow load and aged sludge, does excessive sludge discharge easily lead to the proliferation of filamental bacteria?
Thread Content
The COD load in the inlet water is low, and the levels of nitrogen and phosphorus are also low; the nitrogen and phosphorus levels in the inlet water meet the **Grade A standard for wastewater discharge**. Currently, the sludge is showing signs of aging, and we plan to gradually reduce its concentration. However, we are concerned that if this reduction is not managed properly, it could lead to an overgrowth of filamental bacteria. What issues need to be taken into account during this process to prevent such overgrowth? We seek guidance!
Increase oxygen supply； Adjust pH; add nutrients ； Appropriately increase F/M, etc.
This can occur if not handled properly, and sludge aging and disintegration are likely to happen; be careful not to over-aerate and reduce the dissolved oxygen level appropriately.
