The TIBEAN deep water aerator is the consequent Polyplan development. This type of facility is used successfully worldwide in the areas of dams and lake restoration since 25 years.
Formation of fouling sludge and intensified ammonium production are to be prevented. TIBEAN provides sufficient oxygen for the complete mineralization of the dying biomass.
The cost of producing drinking water should remain low. TIBEAN ensures the oxidation and precipitation of iron and manganese by maintaining an oxygen concentration of 4 mg L-1.
The formation of toxic hydrogen sulfide is to be prevented. TIBEAN prevents reductive processes and thus preventing the formation of hydrogen sulfide due to its oxygen-rich environment.
The nutrient supply in the water body should be reduced. TIBEAN supports the fixation of phosphorus in the sediment. This generally improves water quality (reducing trophic levels).
Till date, Polyplan has designed 75 TIBEAN (TIefenwasserBEüftungsANlage) for various applications in dams, bathing lakes and park ponds.
