In wastewater treatment technologies, a sedimentation tank is employed to remove coarse particles, for example stones, glass splinters or sand, and also coarse natural materials which has not been divided out through the screens.
Both of those of such treatments are usually offered in prefabricated metal tanks called bundle plants. Oxygen aeration systems blend pure oxygen with activated sludge. A richer focus of oxygen allows the aeration the perfect time to be shortened from six to two hrs, lowering the needed tank volume.
