Kill Coliform Bacteria at No Swimming Beach Closure Areas Utilizing CLEAN-FLO Lake Aeration

There are many types of bacteria found in natural waters. Fecal coliform bacteria are not part of the normal microbial populace of the water. Coliform bacteria usually only contaminate water from some external source such as leaking septic tanks or stagnant storm sewers, and are almost invariably of fecal nature, resulting in beach closures. Also fecal coliform bacteria usually do not multiply in natural waters, but are only in a transitory state.

CLEAN-FLO lake aeration will reduce fecal and total coliform bacteria levels and eliminate beach closures in several ways:

Fecal coliform bacteria thrive without oxygen. CLEAN-FLO's unique lake aeration increases the oxygen concentration levels throughout the entire water column, so many of the fecal and total coliform bacteria are killed, resulting in improved water quality and elimination of beach closures.
Coliform bacteria of the fecal type require an organic nutrient broth in order to survive. The CLEAN-FLO lake aeration system allows aerobic beneficial bacteria to consume the organic nutrients, removing them from the water column and eliminating the nutrient broth, reducing beach closures.
Fecal and total Coliform bacteria require carbon dioxide, phosphorus, nitrogen, ammonia or sulfur to live. The CLEAN-FLO lake aeration system reduces the amount of these nutrients in the water, reducing beach closures.
Fecal and total coliform bacteria require an acidic to slightly acidic environment for survival, in the pH range of 5.0 to 6.5. By removing carbon dioxide and removing acid-producing bacteria through steps 1 and 3 above, the CLEAN-FLO aeration system causes water to become more alkaline, reducing beach closures.
Coliform bacteria are killed by ultraviolet light, which the sun emits. This ultraviolet does not penetrate the water deeply, so only surface water is affected under normal conditions. Introduction of CLEAN-FLO's unique lake aeration called Continuous Laminar Flow Inversion & Oxygenation will bring the unaffected bottom waters to the surface, where ultraviolet will kill and or weaken the fecal and total coliform bacteria, resulting in improved water quality and elimination of beach closures.
The CLEAN-FLO lake aeration system creates conditions whereby some aerobic bacteria actually feed on fecal and coliform bacteria, reducing beach closures.

Therefore, as a result of highly oxygenating the water body, creating an environment where aerobic bacteria thrive, reducing the nutrient media, raising the pH and exposing pathogenic bacteria to sunlight, coliform bacteria are weakened or killed. Beach closures are prevented.

After a beach closure, tests by Medallion Laboratories of Minneapolis and the Minneapolis Health Department showed fecal coliform bacteria levels decreased from 310/100 ml to less than 1/100 ml while Streptococci levels decreased from 24/100 ml to less than 1/100 ml after the Clean-Flo lake aeration system was installed in Moore Lake in Minnesota.

Tests by Analytical Laboratories, Inc. of Sioux Falls, South Dakota showed total bacteria coliform in a fish pond in Staples, Minnesota declining from 3000/100 ml down to less than 1 /100 ml after our inversion system was installed.

Lake aeration of 519-acre Powai Lake in Mumbai, India reduced coliform bacteria from 100,000-200,000/100 ml pretreatment level to less than 1,000/100 ml. Lake aeration of 25-acre Kachrali Lake in Thane, India reduced coliform levels more than 99%.

If you are experiencing high fecal bacteria and coliform bacteria levels, resulting in beach closures, the CLEAN-FLO lake aeration system is a perfect cure.

If you are experiencing high bacteria levels, the CLEAN-FLO system is a perfect cure.

Parks and Recreation Department beach closure: A CLEAN-FLO lake inversion system was installed in late April of 2006, a significant drop in coliform bacteria levels was observed after a week of operation. The system was turned off a few weeks after installation and bacteria levels rose. When the system was restarted a decrease in bacteria levels was again recorded, suggesting that the CLEAN-FLO lake aeration system was directly affecting bacteria levels in the lake.

If you are experiencing high fecal bacteria and coliform bacteria levels, resulting in beach closures, the CLEAN-FLO lake aeration system is a perfect cure.
