From The Pueblo Chieftain (Chris Woodka):
Fowler wants to use a patented process that uses single-cell algae to put oxygen into the water, rather than mechanical processes typically used in lagoons, said Wayne Snider, town administrator. Fowler has nine lagoons and will spend about $15,000 on the pilot program by BiO2 Solutions [Ed. website is still under construction.].
iO2 is using a patented process developed by Lonnie Losh, who said he stumbled across the idea while dealing with wastes from his family’s cattle and hog operations near Strasburg, east of Denver. “What we have come up with is a reliable way to treat lagoon waste and return it to the river,” said Losh, president and co-founder of BiO2. Losh said the algae used in his process do not form the filmy layer sometimes associated with algae in ponds, but penetrate the water more deeply to improve oxygenation. Losh partnered with wastewater treatment engineers to expand the treatment to municipal or industrial systems as well as agriculture. The algae, which are grown in greenhouses and mixed into ponds through diffusion equipment, improved oxygen levels above state standards, reduced ammonia concentrations and lowered costs 80 percent in trials at Wray, Guthrie said. The system could also improve how communities such as Fowler use their water, since discharges from lagoons could be year-round instead of annually.
