Biotifx® ULTRA Resolves Odor Issues at a Beverage Manufacturer Lagoon

  • MDG


A west coast beverage manufacturer with evaporative wastewater holding ponds was experiencing strong odor issues and a persistent sludge cap. After a single treatment with Biotifx® ULTRA, the odors and sludge cap were completely eliminated.


A west coast beverage manufacturer was operating evaporative wastewater storage ponds. They produced an average of 35,000 gallons of wastewater per day. The site consisted of 18 storage ponds, each roughly 1.1 million gallons in size. Once a given pond was filled, it would be allowed to dry completely before excavating solids and refilling. The typical cycle included one month to fill the pond, followed by three months of drying. Over time, an issue arose when a persistent sludge cap formed on the surface of the water. This cap started preventing water from evaporating within their normal three-month cycle and it caused the lagoon to become anaerobic, releasing strong, unpleasant odors.


To remove the sludge cap over the lagoon and demonstrate a reduction in odor when treating Biotifx® ULTRA compared to untreated ponds.


Two ponds of similar condition were chosen for the trial. One was treated and one was designated as the control. The treated pond received a single 20kg dose (5ppm) of Biotix® ULTRA. The product was hydrated and dosed from shore at multiple points. Baseline data for all ponds included pictures of scum layer, basic water chemistry monitoring, as well as an odor survey. Odor surveys were conducted by placing a water sample from each pond into a sealed jar. Sample jars were then allowed to rest for 10 minutes. After resting jars were shaken vigorously for 20 seconds and de-capped, they were smelled by each of the three surveyors. Surveyors (including plant personnel) then ranked the odor from 1-10. Ten being the worst and one being least odorous. The procedure was repeated at 2 and 3 weeks after treatment.


After two weeks of treatment, the sludge cap on the lagoon was removed and odor reduction was much greater than in the control lagoon. Three weeks after the initial treatment, the scum layer and odors had been eliminated while both issues still priested in the control pond.
