Air can be included with the churning motion of mechanical propeller-like mixers located within the tank surface area.
Many of the water is eradicated in the stage called thickening and then the sludge is processed read more in large tanks referred to as digesters.
The sewage water is initially permitted to go through a primary wastewater treatment plant. At this time, the treatment works by using screens and settling tanks to get rid of many of the floating components more info through the wastewater.
