Our lakes and other natural waters have been victims of the contamination with nutrients from antrophogen sources for a long time. Also drinking water lakes and reservoires can become eutrophicated by the input of phosphorus and nitrogen from point or diffuse sources. In addition air-transferred contaminations have also to be considered. All these affected waters require assistance for their stabilisation. The problem is indicated as oxygen deficiency in the depth water (hypolimnion) where the decay of the sedimenting organic matter takes place. If nothing is done, the conditions in the lake worsen until no oxygen at all is present. The entire biological life becomes into danger, especially when toxic H2S is generated in the surface of the sediments. The LIMNO offers an effective treatment for stabil stratified lakes suffering from oxygen deficiency.
