Abstract:
... Mainstream anaerobic treatment technologies are a viable alternative to conventional aerobic treatment to recover resources and improve process sustainability. However, resource recovery efforts must be coordinated with efforts to abate environmental risks associated with micropollutants (e.g. pharmaceuticals). The microbial and physical mechanisms of micropollutant removal in mainstream anaerobic ...

Amine-containing pharmaceuticals can be effectively removed by chlorination. These drugs, however, may coexist in wastewater. Thus, they may compete with each other, and their chlorinated products may react with each othe ...
