Designing oxidation-based treatment
Engineers developed a sulfide oxidation system to remove hydrogen sulfide odors efficiently and cost-effectively.
Bel Brands partnered with CDM Smith to design and build a treatment system that eliminates downstream odor issues and meets strict discharge limits, all within an accelerated five-month timeframe before the onset of South Dakota's winter.
Engineers developed a sulfide oxidation system to remove hydrogen sulfide odors efficiently and cost-effectively.
Bench-scale trials determined the ideal air flow, retention time and tank size to achieve complete oxidation results.
A design-build approach allowed the team and its local partners to complete design and construction in just five months.
The 81,250-gallon oxidation tank requires less than 5 hours to fully eliminate odors before discharging the effluent.
The new oxidation system processes high-strength wastewater while maintaining less than 5 ppm hydrogen sulfide in the sewer, meeting Bel Brands’ goals for efficiency and environmental stewardship. By avoiding the use of chemicals or offsite disposal, the system minimizes long-term operating costs and environmental impact. Completed under a demanding schedule, the project showcases the power of collaboration and design-build delivery in achieving swift, sustainable industrial solutions.
