Some people do not realize that a river flows mostly only on the surface. A graph of velocity vectors of river water is parabolic, with zero flow at the bottom and maximum flow at the surface. The surface water of a river is oxygenated by the atmosphere, while the bottom water is usually near-zero mg/l oxygen, and is stagnant. To aid in river improvement and restore water quality, an inversion system is necessary to bring river water from the bottom to the surface. CLEAN-FLO International developed a water treatment process for river improvement to bring river water at the bottom of rivers up to the surface so that the entire river is oxygenated by the atmosphere surface to bottom. Bottom toxic gases are also then neutralized and foul odors quickly disappear. We call this highly specialized aeration system, and water treatment process Continuous Laminar Flow Inversion and Oxygenation. This aeration system results in many benefits for river improvement, including restored water quality. First, inversion and oxygenation enables beneficial bacteria, insects and fish to thrive on the bottom. In the process, beneficial bacteria feed on the organic matter and the organic sediment is biodegraded to carbon dioxide (which the CLEAN-FLO Process and aeration system exhausts to the atmosphere) and water. |

Insects feed on the organic matter and on the bacteria, and fish feed on the insects. The result is a great improvement in fish health, number and growth rate. In any water body, when the bottom is oxygenated, phosphorus and nitrogen in the water column is bound to the sediment, where it becomes food for the beneficial bacteria and insects.
Second, inversion and oxygenation will reduce disease causing bacteria. Many pathogens are strict anaerobes and require a nutrient broth for survival and practically all pathogens are killed by ultraviolet light, which the sun emits. Also aerobic bacteria feed on pathogenic bacteria. 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, these pathogens are weakened or killed.
As a result of utilizing the CLEAN-FLO Continuous Laminar Flow Inversion and Oxygenation aeration system and water treatment process for river improvement, all parameters of water quality greatly improve. The river water then becomes very clean and suitable for everyone’s use.
Helpe Mineure River: As a result of a river improvement project that utilized the CLEAN-FLO inversion and oxygenation aeration system technology, the City of Fourmies, France has been awarded the “Prix de l’Environment” award for cleaning up the Helpe Mineure River. Engineers worked with CLEAN-FLO International during the river improvement project. Some 43 kilometers of the Helpe Mineure River had been classified by the French Government as unsuitable for any use. The river was polluted with wastewater from a screw manufacturing plant, in addition to raw sewage from the city. The entire stretch of the formerly polluted river is now suitable for fishing, washing, and drinking water for animals. Click here for more information on the Helpe Mineure river improvement project.
