摘要: Abstract 530 L high rate alga pond (HRAP) and 380 L airlift tubular photobioreactor (TPBR) were operated compared in a urban wastewater treatment plant (WWTP), with the main purpose of removing nitrogen phosphorous from effluent WWTP while generating valuable biomass. The photosynthetic activity TPBR was during entire experiment higher than HRAP. maximum areal productivity reached 8.26 ± 1.43 21.76 ± 0.3 g SS m−2 d−1 for HRAP respectively. Total (TN) removal averaged 89.68 ± 3.12 65.12 ± 2.87% respectively, total phosphorus (TP) 86.71 ± 0.61 58.78 ± 1.17% lipid content showed no significant differences (p
