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.
