Evaluation of a biologically-based filtration water reclamation plant for removing emerging contaminants: A pilot plant study

► A biological filtration pilot plant based on Daphnia sp. was studied. ► Removal efficiency of emerging contaminants. ► Effect of the hydraulic loading rate, solar radiation and seasonality. ► Removal efficiency ranged from no detectable removal to more than 90%. ► We suggested biodegradation and photodegradation as relevant removal pathways.
