Abstract

Ozone and chloramines are critically important for achieving stringent public health criteria and operational water quality objectives in potable reuse treatment trains, but these disinfectants are also linked to the formation of N-nitrosodimethylamine (NDMA). In the current study, a pilot-scale ozone-biofiltration system was used to treat membrane bioreactor (MBR) filtrate from a full-scale water reclamation facility. Experiments were designed to assess the roles of preoxidation, empty bed contact time (EBCT), and media type on NDMA formation and removal. In biological activated carbon (BAC) and anthracite columns receiving pre-ozonated MBR filtrate, EBCTs... (see abstract in article).
