AB The dynamics of microalgae population during piggery wastewater(PWW) treatment in four open photobioreactors operated at 27 days ofhydraulic retention time, and inoculated with Chlorella sp. (R1),Acutodesmus obliquus (R2), Oscillatoria sp. (R3) and in the absence ofinoculum (R4), were evaluated for 6 months. In addition, the algalbacterialbiomass concentration, removal of organic matter, nutrients andheavy metals were also assessed. The results revealed a high diversityand rapid variations in the structure of microalgae populations,Chlorella sp. being dominant in R4 throughout most of the operationalperiod. Steady state average biomass concentration ranged from 2445-2610mg/L in R1-R3 to 3265 mg/L in R4. No significant differences wererecorded in the removal efficiencies (REs) of total organic carbon (86-87%), inorganic carbon (62-71%), total nitrogen (82-85%) and totalphosphorous (90-92%). Finally, Zn-REs accounted for 26% in R3, 37% in R2,and 49% in R1 and R4.
