Comanche Livestock was established near Strasburg, CO in 1970, growing to a 1,800-sow farrow-to-finish operation. Since that time Denver expansion has crept ever closer, with some developments nearby. Odor had become a challenge for the operation, and was certain to eventually become a bigger issue. Solids build-up were a problem, with the lagoons requiring two separate clean-outs at a cost of $75,000 each time.
The goal was to be envirnomentaly-responsible by reducing odors and sludge buildup, increase dissolved oxygen levels, creating an effluent wastewater stream at a standard acceptable for center pivot irrigation
The primary wastewater lagoon had 6 feet of sludge, 2 feet of liquid, and a surface crust ranging from 6 inches to 18 inches. Dissolved oxygen levels in what liquid media remained in the center were less than 1.0 mg/L. The existing effluent was of such poor quality that it continually plugged the irrigation sprinklers.
The BiO2 Solution™ green technology cultivates microalgae that act like biological oxygen compressors. This patented formula of multi-species single-cell microalgae was introduced into the primary wastewater lagoon. These microalgae provided abundant oxygen to the lagoon and initiated, perpetuated, and maintained the process of rapid aerobic digestion.
- Odor was effectively reduced from the lagoons
- Crusting at the surface was eliminated
- Sludge build-up on the bottom was reduced.
- Readings for BOD, TSS, KN and NH3 were reduced.
- Dissolved oxygen levels increased to the point that full aerobic digestion is occurring throughout the waste material
