Sewage sludge treatment - Wikipedia
The treatment can take place in the sewage treatment plant itself (by recycling the liquid to the start of the treatment process) or as a separate process. Phosphorus recovery Edit One method for treating sludge dewatering streams is by using a process that is also used for phosphorus recovery.

Wastewater treatment - Primary treatment | Britannica.com
Wastewater treatment - Primary treatment: Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars. They block floating debris such as wood, rags, and other bulky objects that could clog pipes or pumps.
