Removal and fate of 18 bisphenols in lab-scale algal bioreactors

The removal of 18 bisphenols at wastewater relevant concentrations (μgL−1range) was investigated and com-pared between Chlorella vulgaris cultures with pH adjusted to 6.8 and pH non-adjusted cultures where pH raised to above 10. Bisphenols with a high partition coefficient (log P > 6) partitioned to biomass soon after spiking, whereas bisphenols with a low partition coefficient (log P < 4) remained largely in the aqueous phase. Hydro-phobic bisphenols and BPF isomers were removed to a large degree in pH adjusted conditions, while BPS and BPAF were the most recalcitrant. The overall average removal after 13 days was similar in both experiments, with 72 ± 2% and 73 ± 5% removed in pH non-adjusted and pH adjusted series, respectively. The removal cor-related with chlorophyll concentration for most bisphenols meaning that algae played a crucial role in their removal, while culture pH also governed the removal of some compounds.
