Water treatment, where does the solid waste (poop) go?

Question

So the typical answer is that it separated via a straining process, sanitized and taken to an incinerator or landfill. Since landfills are far more popular in the U.S., focus on that. Is it stored separately from the rest of the trash, that is, how is it processed at the landfill?

Answer 1

No, the solid waste (poop) does not go to a landfill or an incinerator. It is "composted" into a sludge.

Typically, sludges are thickened (dewatered) to reduce the volumes transported off-site for disposal. There is no process which completely eliminates the need to dispose of biosolids. There is, however, an additional step some cities are taking to superheat the wastewater sludge and convert it into small pelletized granules that are high in nitrogen and other organic materials. This product is then sold to local farmers and turf farms as a soil amendment or fertilizer, reducing the amount of space required to dispose of sludge in landfills

Answer 2

Bacteria break down feces very well. They do it in large tanks called 'digesters'. There are even special strains of bacteria specifically for use in large-scale waste treatment plants that work aerobically (with oxygen).

The waste product from the bacteriological breakdown of feces is semi-inert sludge that can be safely put into the ground in landfills.

Answer 3

I thought it was broken down by chemicals and machinery at the water facility until it was gone, saw something similar on Dirty Jobs with Mike Rowe before, but not 100% sure, I am no poop expert for sure, good question though
