Free chlorine can also be introduced through the injection of ...

  • Removal of APIs and bacteria from hospital wastewater by MBR plus O3, O3 + H2O2, PAC or ClO2

    The objective of this study has been to develop technologies that can reduce the content of active pharmaceutical ingredients (APIs) and bacteria from hospital wastewater. The results from the laboratory- and pilot-scale testings showed that efficient removal of the vast majority of APIs could be achieved by a membrane bioreactor (MBR) followed by ozone, ozone + hydrogen peroxide or ...
