In wastewater treatment technologies, a sedimentation tank is applied to eliminate coarse particles, like stones, glass splinters or sand, along with coarse natural product which includes not been separated out because of the screens.
Both of those of such treatments are generally furnished in prefabricated steel tanks named deal plants. Oxygen aeration systems combine pure oxygen with activated sludge.
