Reduce Fecal Coliforms
  1. 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

  1. Fecal coliform reduction in municipal waste (utilizing - 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

  2. 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. Enviro Series 200.

    After machines installation:
    May 10, 1995



    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.
