Abstract
Systems and methods for treating wastewater are disclosed. Zero valent iron media may be used in a moving packed bed reactor. A media recovery system may return media to the reactor.
Claims26
A wastewater treatment system, comprising:
- a wastewater inlet;
- a vessel including a moving packed media bed, the vessel configured to receive wastewater to be treated from the wastewater inlet and to contact the wastewater to be treated with a catalyzing media in the moving packed media bed to produce treated water;
- an effluent outlet in fluid communication with the vessel and configured to receive the treated water from the vessel;
- and
- a media recirculation system configured to transport catalyzing media from a first portion of the moving packed media bed to a second portion of the moving packed media bed.

A wastewater treatment system, comprising:
- a wastewater inlet;
- a vessel including a moving packed media bed, the vessel configured to receive wastewater to be treated from the wastewater inlet and to contact the wastewater to be treated with a catalyzing media in the moving packed media bed to produce treated water;
- an effluent outlet in fluid communication with the vessel and configured to receive the treated wastewater from the vessel;
- a media recirculation system configured to transport catalyzing media from a first portion of the moving packed media bed to a second portion of the moving packed media bed;
- and
- a media recovery system in fluid communication with the effluent outlet and configured to remove catalyzing media from the effluent and return the removed catalyzing media to the vessel.
3 more elements
A method of treating wastewater, the method comprising:
- introducing the wastewater into a reactor including a catalyzing media;
- contacting the wastewater with the catalyzing media in the reactor to form an effluent;
- moving a portion of the catalyzing media from a first position in the reactor to a second position in the reactor;
- removing the effluent from the reactor;
- removing catalyzing media from the effluent removed from the reactor;
- and
- recycling the removed catalyzing media to the reactor.
4 more elements
A wastewater treatment system, comprising:
- a wastewater inlet in fluid communication with a source of wastewater including a soluble heavy metal contaminant;
- a vessel configured to receive wastewater to be treated from the wastewater inlet and contact the wastewater to be treated with a catalyzing media in the vessel, the catalyzing media configured to one of precipitate and adsorb at least a portion of the soluble heavy metal contaminant and produce treated water;
- an effluent outlet in fluid communication with the vessel and configured to receive the treated water from the vessel;
- and
- a media recovery system in fluid communication with the effluent outlet and configured to selectively remove active catalyzing media as compared to spent catalyzing media from the treated water and return the active catalyzing media to the vessel.
2 more elements
A method of treating wastewater including a soluble contaminant, the method comprising:
- introducing the wastewater into a vessel including a catalyzing media, the catalyzing media configured to one of precipitate and adsorb at least a portion of the soluble contaminant and produce treated water;
- removing the treated water from an effluent outlet in fluid communication with the vessel;
- selectively removing active catalyzing media as compared to spent catalyzing media from the treated water;
- and
- returning the active catalyzing media to the vessel.
