ODOR CONTROL
Beco has provided odor control systems for a variety of challenging odor problems. Using various wet scrubber technologies and detailed knowledge of the specific chemistries, we have resolved the following industrial odor problems:
- Soap Perfume (Colgate-Palmolive)
- Fish Meal (Sandoz)
- Vinegar, alcohols (17 plants of Fleischmann's Yeast)
- Chili Powder (Rogers Food)
- Acrylates, etc., (Asia Pacific Specialties, Australia)
- Butyl hydroxytoluene (Diamond-Shamrock)
- Ketchup (H. J. Heinz)
- Hydrogen Sulfide (Petrolite)
- Mercapto-ethanol (Akcros Chemicals America)

WASTEWATER TREATMENT PLANTS
By optimizing the kinetics of the sulfide and mercaptan absorption reactions, Beco has been able to effectively use spray-contact scrubbers for odor control on wastewater plants. The use of short contact-time spray absorbers avoids the sulfur plugging problems that normally plague packed scrubber operation.
Beco has provided wastewater odor control scrubbers for both small and large municipal treatment plants. The latter have included scrubbers on two of the largest trickling filters in the U.S. at the West New York, New Jersey, secondary treatment plant. At Bristol, Connecticut, a Beco scrubber using hydrogen peroxide as the odor oxidant has been in successful operation since 1988 on sludge holding tanks.
