I'd like to develop a system for homes far from sewage lines whereby
feces are spun in a thing like a washing machine causing liquids to be
spun out. The resulting mass would be scraped off and then dried with a
solar dryer, compacted into bricks and later collected like garbage.
This would eliminate the necessity to run expensive sewer lines to each
home. However, what to do with the liquid waste? First you separate
grey water from urine and leftover water from the feces. Then you use
some sort of electrical ozone generator to sterilize it. Then the tough
part comes, removing the nutrients............

Are you familiar with composting toilets? Except for the grey water,
it's pretty much what you are describing, if I'm understanding you
correctly.

Not my field of expertise ;-), but it might be doable. Without using
water, the volume is considerably less. Everything is centrally
located. There are high volume composting systems, but retrofitting
could be a bitch.

You have to question how it is done now. Hopefully, the water treatment
is better than is was 20 years ago when you could see hundreds of Coney
Island Whitefish floating in the NY harbor.
