Answer 1

It depends on the type of water waste treatment.
Sewage: http://en.wikipedia.org/wiki/Sewage_treatment
Industrial: http://en.wikipedia.org/wiki/Industrial_wastewater_treatment
Agriculture: http://en.wikipedia.org/wiki/Agricultural_wastewater_treatment

The most common is sewage because each industry and company handles its own sewage treatment.

Cities, towns and municipalities handle sewage. The waste from the street sewers is rarely treated like sewage; it is mostly clean rain water with debris. So it is run through underground tunnels to empty in a nearby river, stream, etc. It may have a grate to filter our large debris and to keep people out of the tunnels, but little else is done to clean or treat it.

Sewer waste that goes down the drain or the toilet has a wide range of solid and liquid waste, human and animal waste, food, paper, and anything else that gets thrown into the toilet or down the drain.

In this system the water is filtered and large waste is removed. It is then let to sit in filtration ponds where either evaporation removes the water or the water leaches through the gravel and filter material to come out underneath. Then it is treated with chemicals like chlorine to purify it. Fluoride is added and it is put back into the drinking water system.

1. Primary treatment and removal of large objects, then sand and grit.
2. Secondary treatment with activated sludge (bacteria is used to destroy organic matter), filtered, membranes, and biological reactors are used to further treat the waste.
3. Tertiary treatment using settling ponds, lagooning, and disinfection.

You can expect to work with a lot of pipes and filters that run liquids around, add chemicals and remove waste. Then there will be large circular open pools, some even have a rotating grate. Finally, there will be hazardous chemicals like Chlorine and Fluorine.

Answer 2

Well, they take poopy water and make it water that you drink.

The process really involves a lot of running the water through filters, but it also involves adding chemicals that cause phosphorus to collect on the bottom as to remove it.
