TYPE OF EQUIPMENT:
Vertical biofilter tower.

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.
