Reduce Fecal Coliforms |
 |
|
- Fecal coliform counts in a recreational lake in Quebec (1997) were registered
at 300 cfu/100 ml, however after pond mills were installed and effectively
remediating (1998), these values declined quickly to less
than 2 cfu/100 ml. Enviro
Series 600
Lake - Quebec, Canada
- Fecal coliform reduction in municipal waste (utilizing ¼ - 1/3 the required
Enviro Series 600 machine numbers) - Southern Saskatchewan.
Waste water was used for crop irrigation.
- Before machines installation (March 14, 1991): 9300 mpn orgs/mL
- After machines installation (June 11, 1991): 40 mpn orgs/mL
Note: Analysis conducted by Water Quality Branch, Sask. Environment & Public Safety
- Another study on livestock effluent in 2001-02 showed a significant reduction of
total coliform bacteria from a high of 700,000 cfu/ml decline to
less than 1 cfu/ml. The
fecal coliform bacteria in the same sample dropped to less
than 1 cfu/ml from a high of
400,000 cfu/ml. The beneficial aerobic bacterial counts in the same sample
increased significantly from a low of 5,700 cfu/ml to a high of 26 zillion cfu/ml.

Although it was noted that there were insufficient machines to handle
the organic and nutrient load of the facility, it's interesting to note
the significant change in microbial population dynamics. The lagoon
changes from an obligate to facultative anaerobic lagoon, to a
facultative/facultative aerobic lagoon.
There is a significant increase in aerobic organisms
with an insignificant increase in anaerobic organisms.
