Removal characteristics of DON in pharmaceutical wastewater and its influence on the N-nitrosodimethylamine formation potential and acute toxicity of DOM
Anaerobic and MBBR process are effective at removing DON. DON and DOC removal are not coupled as well as their molecular changes. DON fractions play significant roles in NDMA formation and acute toxicity of DOM. Measurement of DON and its fractions are recommended in pharmaceutical wastewater.
