Odor (VOC) Bio-Filtration and Bio-Gas Scrubbers

Odor (VOC) Bio-Filtration

Odor and other forms of air pollution are rapidly becoming major U.S. problems.  PBS has developed simple and effective air pollution control devices for the abatement of Odor and VOC emissions.

An example of Odor Bio-Filtration is the air cleaning system at Coors Brewing Company, Golden,

Colorado, wherein upflow beds of biologically activated Iron Sponge are employed to remove 

Hydrogen Sulfide chemically, and other organic odor components biologically.

PBS offers large site-constructed beds, modular fiberglass Bio-Filters for the removal of a variety of volatile organic compounds from gas streams.  Bio-Filter design and materials of construction depend upon the specific Odor/VOC problem.  All Bio-Filter designs are low cost and simple to operate, generally requiring no chemical additions.

Hydrogen Sulfide Filters are routinely employed in all PBS anaerobic system designs.  These Filters, packed with Iron Sponge Media for the removal of Hydrogen Sulfide, generally last for years without media change-out and routinely reduce Hydrogen Sulfide concentration by over 99%.

Hydrogen Sulfide Monitors

Phoenix Bio-Systems, Inc. also provides a simple and effective means of on-line monitoring for H₂S in Bio-gas.  Our H₂S Monitor is used to continuously measure H₂S on-line, which helps to measure and control Sulfur Dioxide emissions in flared bio-gas, particularly in conjunction with our scrubber systems.  The monitor is provided with constant pressure/flow micro-pumps and a unique dilution control system which allows the on-line measurement of H₂S in very high concentrations.  The monitor is easy to install, calibrate and operate, and is designed for use with PLC and DCS systems.
