An increase in bubbles in the wastewater on a large scale?
Thread Content
Recently, the bubbles used to treat wastewater have increased significantly; there are sticky substances present, which make it difficult for the bubbles to shrink. The bubbles have become larger and brown in color. Need a solution? ? ? ? ?
It is recommended to check the water inflow load and water quality.
The reasons for this situation may be: 1. The raw water contains a large amount of surfactants. 2. The large amount of lipid substances produced during microbial reproduction. 3. Sludge denitrification foam. Items 2 and 3 are the most likely (based on large foam, brown color, and viscosity)
The foam is brown and sticky, indicating that it is biological foam. To temporarily eliminate it, tap water can be sprayed on it. An increased water inflow rate, low dissolved oxygen levels, and a high pH value can all lead to the formation of biological foam
