Percentage
of influent and effluent carbon (A) and nitrogen (B)
fluxes, under normal and reduced mass transfer conditions (S1, kLa = 34 d–1 and S2, kLa = 0.5
d–1). The S1 and S2 scenarios were analyzed according
to seasons: spring, summer, autumn, and winter. In Figure 4A, C-ORG, PARTICULATE is the
organic carbon present in XS and XI fractions; C-ORG, SOLUBLE is the organic carbon
present in SS and SI fractions; C-ALG, C-NIT, and C-HET are the organic fractions
present in the algal, nitrifying (AOB and NOB) and heterotrophic biomass,
respectively. In Figure 4B, N-ORG is the organic nitrogen present in XS, XI, SS, and SI fractions; N-ALG, N-NIT, and
N-HET are the organic nitrogen fractions present in the algal, nitrifying
(AOB and NOB) and heterotrophic biomass, respectively. The computed
fluxes of N2, NH3 and CO2 are gaseous,
while all other are liquid fluxes.
