Abstract
The invention is directed to a method and apparatus for treating wastewater. The wastewater treatment system includes a bioreactor including activated carbon and a first biological population. The wastewater treatment system may also include a membrane bioreactor and/or a wet oxidation unit.
Claims37
A wastewater treatment system comprising:
- a source of wastewater comprising a concentration of an endocrine disrupting compound;
- a bioreactor fluidly connected downstream of the source of wastewater, the bioreactor comprising an adsorbent;
- and
- an adsorbent regeneration unit fluidly connected downstream of the bioreactor.
A wastewater treatment system comprising:
- a source of wastewater;
- a first membrane bioreactor fluidly connected to the source of wastewater, the bioreactor comprising an adsorbent;
- and
- a wet air oxidation unit fluidly connected to the bioreactor.
A wastewater treatment system comprising:
- a source of wastewater;
- a first bioreactor fluidly connected to the source of wastewater, the first bioreactor comprising an adsorbent;
- a second bioreactor fluidly connected downstream of the first bioreactor;
- and
- a separator fluidly connected downstream of the first bioreactor and upstream of the second bioreactor.
A wastewater treatment system comprising:
- a source of wastewater;
- a wet air oxidation unit comprising an inlet fluidly connected to the source of wastewater and an outlet;
- and
- a membrane bioreactor comprising a biological population and fluidly connected to the outlet.
A wastewater treatment system comprising:
- a source of wastewater;
- a bioreactor fluidly connected downstream of the source of wastewater, the bioreactor comprising an adsorbent;
- and
- an adsorbent regeneration unit fluidly connected downstream of the bioreactor, wherein the adsorbent regeneration unit comprises a second bioreactor.
A wastewater treatment system comprising:
- a source of wastewater;
- a bioreactor fluidly connected downstream of the source of wastewater, the bioreactor comprising an adsorbent;
- an adsorbent regeneration unit fluidly connected downstream of the bioreactor and
- a separator selected from the group consisting of a hydrocyclone and a membrane bioreactor fluidly connected downstream of the bioreactor and fluidly connected upstream of the adsorbent regeneration unit.
