Customer Problem
As is common to many manufacturing facilities, the customer faced foul odors associated with
their waste treatment operations. In addition, the customer faced a challenge to control the
level of H2S within the legal limit.
The project concentrated on the manholes in which odor and H2S escaped into the surrounding
areas. The overall length of the sewage system was 21 km, and the total retention time was 2.5
hours (approximate time the probiotic products had to impact the wastewater quality).
Goal
- To control foul odors in the sewage system escaping from the manholes area, reducing
complaints from surrounding neighbors;
- To reduce the levels of Hydrogen Sulfide (H2S) to within the legal guidelines (<35ppm).
Methodology
Daily waste generated from the distillery is 210,000 - 3,100,000 liters, depending on seasonal
fermentation process. Approximately 700 liters of liquid SCD Probiotics were applied directly
to the wastewater treatment system prior to aeration process from the treatment system (see
Exhibits 1 and II).
Results
Results were obtained before and after treatment of SCD Probiotics. Readings were taken by
the personnel of the distillery. Baseline data was gathered in 2006, while data after the SCD
Probiotic treatment applications was taken from April 2008 to June 2009. Hydrogen sulfide
(H2S) data was taken 3 times per day, at 7:00, 2:00 and 10:00.
Significant results were demonstrated and all goals of the project were achieved.
- H2S is reduced to well below the legal limit (Exhibit 3)
- Odor complaints from the surrounding neighbors are virtully non-existant (Exhbit 4)
