A pilot system containing a particularly designed configuration of pri
mary flotation unit and a combined flotation-filtration clarifier, was
used for advanced municipal wastewater treatment. The system which wa
s investigated demonstrated the feasibility of municipal wastewater tr
eatment by the flotation separation of fluid and coagulated-flocculate
d solids (Total suspended solids (TSS), organic load, Phosphorous (P),
Total Kjeldahl Nitrogen (TKN)) without using microbiological oxidatio
n. The particular objective herein was to create a preliminary approac
h to theoretical evaluation of positive pilot-study results in the for
m of two kinetic models. Based on positive pilot results, and kinetic
analysis, the following conclusions were reached: A double-stage flota
tion/filtration system might be a viable alternative for municipal was
tewater treatment. Empirical models and prediction developed here refl
ect the kinetics of the removal of coagulated and flocculated solids b
y flotation.
