Odor Control - Solid Waste Collection Site Application
A Waste Management Solid Waste Transfer Station was receiving numerous complaints
from residents living around their facility. The transfer station is located in the
center of a residential area and in an effort to mend the company’s relationship
with the community the plant manager was seeking a solution to the odor problems.
The odors were being created by several different sources. Many of the dumpsters
used in the transfer of waste from the collection sites to the transfer station were
notorious for emitting offensive odors. The transfer station physical plant was also
responsible for odor problems. As the waste was dumped into the transfer station
bays for separation and reloading, odors were being generated by runoff from the
piles. This runoff was also causing a serious concrete corrosion problem resulting
from leaching hydrogen sulfide. The plant manager estimated that 50% of the transfer
stations concrete floor had been eroded away over the past 8 years. Finally, the
retention pond located behind the transfer station was also a major contributor to
the odor problems at the transfer station.
Tests were conducted by using the Bio1 in the normal wash down cycle of the dumpsters
and plant physical facility. The product was applied through the chemical intake
line of a pressure wash system at a rate of 6 ounces per gallon of water. The treatment
resulted in an immediately improvement in the reduction of offensive odors. The product
was most notably effective when it was used to rinse a dumpster that was used for
waste collection at a seafood restaurant.
This particular collection site was notorious for producing extremely offensive odors
in the collection dumpster. After the rinse down was completed the plant employees
were amazed at the dramatic reduction in the odors. The results from the wash down
of the physical plant facility were good, but less impressive than the dumpster’s
tests. While the treatment did improve the air quality in the facility, the presence
of waste transfer trailers loaded with fermenting waste distorted the test results.
The retention pond was shocked with a 100-PPM treatment of Bio1. An immediate reduction
in the hydrogen sulfide (H2S) levels were observed. 24-hours after the shock treatment,
odors from the retention pond were reduced to levels that could only be detected
in the immediate area surrounding the pond. A daily maintenance program was recommended
with a metering rate of 10 PPM of Bio1 to continue control of the odors.
The treatment of the collection dumpsters and retention pond resulted in outstanding
reductions in odors. The application of the product in dumpster applications required
no additional clean-up steps as the product was introduced through the use of the
chemical uptake line on the existing pressure washing system. The initial treatment
of the retention pond required a system shock, but the daily maintenance would require
no additional personnel involvement as a metering pump was utilized to inject the
product into the pond.
Bio1 is non-corrosive so the degragation of concrete is lessened.
All Organic Products Company products are noncorrosive, nonpathogenic and safe to
store and use. They are harmless to people, pets and wild life if used as directed.
