Model BIO-DESOLF Series -Biological Biogas Desulphurization Vertical Biofilter Towers
Operating Principals: In anaerobic fermentation of waste for biogas production, the methane produced contains high levels of hydrogen sulphide which is highly corrosive for the power production unit.
Our BIO-DESOLF plants reduce the hydrogen sulphide content through a biological treatment, without chemical reagents consumption.
A correct BIO-DESOLF management has to control the following operative parameters: temperature, pH, oxygen quantity and nutritional substances.
BIO-DESOLF efficiency in optimal working conditions is more than 90%. In plants where could happen important changes in biogas’ flow o in H2S concentration, we advice the installation of a chemical desulphurization plant (DESOLF-VTR) after BIO-DESOLF, to guarantee a very high efficiency in H2S removal even with large changes in biogas flow or H2S concentration in the gas to be treated.
