Sewerage is just a load of crap. If you think this you are on the wrong track. It can be a valuable commodity. The cleaning process begins with a giant comb that lets the good stuff through and blocks the solids - tampons, tennis balls, toys, sneakers, marbles, cardboard and so on are discarded.
The second stage involves very fine polymer membranes. The membrane pores are less than a millionth of a millimeter thick which filters out microscopic contaminants. That is all there is to it, just fine filters
Purified sewerage is used to water crops and is pumped into the mains water supply for drinking by the public. It is claimed that it is better than bottled water from mineral springs. This of course is a bold-faced lie. It still contains some ultra-fine remnants of crap!
