A pump transports the clean sludge to what is called a digestion tower.
As wastewater enters a plant for treatment, it flows by way of a display. This removes substantial floating objects, which include rags and sticks, which clog pipes or destruction devices.
Immediately after biological treatment, approximately ninety% from the wastewater is cleaned of biodegradable substances.
