The conventional technology is
aerobic activated sludge.
It is based on optimizing conditions
for selected biological organisms
to metabolize (Monod kinetics) human waste
into biomass (sludge)
which can be disposed of
or anaerobically converted in methane gas.

Nano technology could help system performance in:
Influent nutrient monitoring
Oxygen supply
Fluid mechanical mixing shear
Sedimentation performance
Effluent monitoring

Strictly physico chemical process are probably still
too expensive (energy intensive) with or without
nanotechnology.
