How to deal with the thick layer of scum in the aerobic tank of a wastewater treatment plant
Thread Content
In our aerobic tank, a large number of bacteria have died, which has resulted in the formation of a thick layer of scum on the surface of the tank. This scum accumulates at the top, and it cannot be removed even by spraying water. Is there any effective way to get rid of it? Ours has a thick layer now.
If there is a lack of nutrients in the water or an excess of harmful substances that poison the fungi, it will cause the fungi to die and float to the surface
This part is dead mud, and its low density due to the presence of bubbles makes it difficult to settle； Generally, an overflow method is used to introduce water into the sludge collection tank ； Alternatively, stirring and spraying can be used to remove the bubbles from the sludge so that it sinks ； If the scum is caused by filaments, the only options are overflow or skimming.
