RAS, or Return Activated Sludge, is a process in sewage treatment plants where a portion of the activated sludge from the secondary clarifier is recycled back to the aeration tank. This recycling helps maintain a high concentration of microorganisms, which are essential for breaking down organic matter in wastewater. By returning RAS, the efficiency of the treatment process is enhanced, allowing for better removal of pollutants before the treated water is discharged or further processed.

Sewage treatment is an essential process in a more advanced society. Untreated sewage can reenter the water system and spread disease. Land around a sewage treatment plant would be cheap, as it is a less desirable area to live, because of the bad smell.
Sewage travels from your home by pipes. The flow is due to the slope of the pipes so the sewage is essentially flowing downhill to a collection well or pit. The collected sewage is pumped from the pits into a forcemain which pressures the material to a sewage treatment plant. In rural ares or industrial parks sewage sometimes flows to a collection tank which is pumped out and into a truck which carries it to sewage plant for discharge to the treatment system
