Abstract
A biofiltration system for treating biodegradable airborne contaminants such as VOCS includes a bio-reactor chamber with a sealed housing, and a heater for maintaining a temperature within the chamber. Several fabric-based bio-reactor panels are mounted within the chamber and are kept in a dampened state by means of an applicator system which applies a temperature-controlled liquid mixture containing microbes and nutrients to the bio-reactor panels. An air handling system moves air laden with biodegradable contaminants through the chamber and over the surfaces of the bio-reactor panels.
Claims20
A biofiltration system for treating biodegradable airborne contaminants, comprising:
- a bio-reactor chamber comprising a sealed housing;
- a heating system for maintaining the temperature within said chamber within a predetermined range;
- a plurality of bio-reactor surfaces mounted within said chamber;
- and
- an air handling system for moving air laden with biodegradable contaminants through said chamber and over the surfaces of said bio-reactor surfaces.
A biofiltration system for treating biodegradable airborne contaminants, comprising:
- a bio-reactor chamber comprising a sealed housing;
- a heater for maintaining the temperature within said chamber within a predetermined range;
- a plurality of bio-reactor panels mounted within said chamber;
- an applicator system for applying a liquid mixture containing microbes and nutrients to said bio-reactor panels;
- and
- an air handling system for moving air laden with biodegradable contaminants through said chamber and over the surfaces of said bio-reactor panels.
A biofiltration system for treating airborne volatile organic compounds (VOCS), comprising:
- a bio-reactor chamber comprising a sealed housing;
- a heater for maintaining the temperature within said chamber within a predetermined optimum range;
- a plurality of fabric-based bio-reactor panels mounted within said chamber;
- a system for applying a temperature-controlled liquid mixture containing microbes and nutrients to said bio-reactor panels;
- and
- an air handling system for moving air laden with VOC through said chamber and over the surfaces of said bio-reactor panels.
A method for operating a biofiltration system for treating airborne volatile organic compounds (VOCS), comprising the steps of:
- defining a plurality of airflow passages extending between bio-reactor panels contained within a sealed housing;
- heating the interior of said sealed housing, including said bio-reactor panels, to a temperature suited to promote the growth of VOC-consuming microbes;
- applying a liquid mixture containing microbes and nutrients to said bio-reactor panels using a recirculation system;
- and
- passing air laden with VOCS through said housing such that said VOC-laden air impinges upon said bio-reactor panels while flowing through said airflow passages, such that microbes carried upon said bio-reactor panels will reduce the amount of VOCS within the air moving through the housing.
