The nitrifying trickling filter (NTF) is a process commonly used in wastewater treatment to remove ammonia. What is less clear is its ability to remove emerging organic contaminants. This study evaluated the potential of NTF to remove eight trace organic chemicals of concern (CoCs), with initial concentration of caffeine, bisphenol A, benzotriazole, trimethoprim and acetaminophen 1 mg L−1, atrazine 2 mg L−1, 17α-ethynylestradiol 5 mg L−1 and N, N-diethyl-m-toluamide 10 mg L−1, using a laboratory-scale NTF system. The impact of initial nitrification rate on chemicals' removal and the impact of chemicals on nitrification rate were investigated.
