How can the sludge settling ratio be increased quickly?
Thread Content
There has been no water inflow into the wastewater treatment system for a long time, resulting in the sludge level dropping to 3. Recently, the amount of ammonia added increased; the ammonia nitrogen level in the aerobic tank is 300 while COD is 500+. The temperature is 29 degrees and the pH value is 8, though it has risen recently before dropping again. Does backflow have any impact on the settling ratio? It’s been a long time since dilution water was added. Everyone, **please help analyze the reasons for the decrease in sludge volume. How can I improve the sludge settling ratio? I’m a beginner!** ! Thank you! !
The increase in sludge SV depends on the proliferation and sedimentation properties of the sludge. The key is to ensure the healthy growth of the sludge, which requires proper control of the physical and chemical conditions of the microorganisms. You can analyze the operating conditions of the wastewater treatment plant carefully and make adjustments accordingly.
As a newcomer myself, I can’t offer any advice. Still push it a bit.
