Nestled in the famous horse country of Virginia are the Goose Creek Waste Water Treatment Polishing lagoons. Experienced in lake management, aquaculture, and industrial waste treatment, Alken-Murray sought to expand its knowledge and experience biological augmentation of municipal waste treatment. In 1991, Alken-Murray selected several facilities to offer free of charge test trials of various Alken Clear-Flo® formulas. Loudon County Sanitation Authority was approached with a proposal to treat its three Goose Creek lagoons, known for persistent problems with odor and an overgrowth of algae. Since the Goosecreek lagoon system was not subject to industrial waste influents and had not experience difficulty meeting its high discharge limits, serious industrial remediation was not required.
After an extensive exchange of knowledge, a treatment program was authorized,utilizing Alken Clear-Flo® 1000, an inexpensive, gentle,but effective general waste degrader that competes with algae for nutrients present in the water, would be the most suitable choice. By rapidly reducing BOD, CF 1000 is also designed to reduce odors.
Seeding of the three lagoons began on August 22nd. Within one week, odors and algae were reduced. Greater improvement was seen by September 8th. By the end of September, the lagoons were so clean they could be mistaken for decorative lakes.
The photographs illustrate the algae and turbidity reduction in lagoons #2 and #3. We did not include photographs of lagoon #1 since it was in better condition at the beginning of treatment and was therefore incapable of demonstrating as much improvement. Since we have not yet mastered the technique of "scratch and sniff" printing, one will have to take our word for odor reduction.
