Abstract
A bioreactor for separating contaminants from fluid and degrading the separated contaminants is disclosed.
Claims10
A bioreactor for separating contaminants from a contaminated gas and degrading separated contaminants comprising:
- a contaminated gas source;
- a reaction chamber having a contaminated gas inlet positioned in an upper portion of said reaction chamber and a decontaminated gas outlet positioned in a lower portion of said reaction chamber, said contaminated gas inlet being connected to said contaminated gas source;
- packing material located within said reaction chamber;
- microorganisms associated with said packing material, said microorganisms being capable of separating said contaminants from said contaminated gas and degrading said contaminants subsequent to separation from said contaminated gas;
- and
- a packing material circulator connected to said reaction chamber, wherein said packing material circulator includes a packing material outlet located in a wall of said reaction chamber in said lower portion of said reaction chamber, a packing material inlet located in said wall of said reaction chamber in said upper portion of said reaction chamber and a packing material conveyor connected to said packing material inlet and said packing material outlet.

A bioreactor for separating contaminants from a contaminated gas and degrading separated contaminants comprising:
- a reaction chamber with a wall containing a packing material, said reaction chamber having a contaminated gas inlet positioned in said wall in an upper portion of said reaction chamber, a decontaminated gas outlet positioned in said wall in a lower portion of said reaction chamber, a packing material outlet positioned in said wall in said lower portion of said reaction chamber, and a packing material inlet positioned in said wall in said upper portion of said reaction chamber;
- a contaminated gas source connected to said contaminated gas inlet;
- microorganisms associated with said packing material, said microorganisms being capable of separating said contaminants from said contaminated gas and degrading said separated contaminants;
- and
- a packing material circulator connected to said packing material outlet and to said packing material inlet of said reaction chamber for circulating said packing material, said packing material circulator having a packing material conveyor connected to convey said packing material through said packing material circulator from said packing material outlet to said packing material inlet.
