1. Start the bubble
In the initial stage of activated sludge process operation, because the sewage contains some surface active substances, it is easy to cause surface foam. But with the aging of activated sludge, these surface active substances are biodegraded, and the foam phenomenon of vegetable foam box will gradually disappear.
2. Denitrifying foam
If the sewage plant conducts nitrification reaction, denitrification will occur in the sedimentation tank or the place where the aeration is insufficient, and bubbles such as nitrogen will occur to drive part of the sludge to float, showing a foam phenomenon.
Vegetable foam boxes are more environmentally friendly than pulp. We all know that pulp is produced with green plants and requires a lot of natural resources. For this product, this kind of pulp is a waste of resources.
