Studies on a new stainless steel mesh dynamic membrane for wastewater treatment.

In this study an innovative dynamic membrane bioreactor (DMBR) was implemented from a stainless-steel mesh filter, which was used as a support material, and activated sludge used as an adsorption and filtration interface containing particulate organics. This work indicated that DMBR can achieve rapid solid-liquid pollutants separation. The activated sludge in the aeration tank quickly formed a thin dynamic membrane layer on the filter.
