SiGa-Tech filters are used for high efficient removal of siloxanes which are organic silicon compounds and considerable H2S reduction.
Siloxanes are responsible for deposit forming which cause damage of generator motor elements. Hydrogen sulfide on the other hand in connection with high humidity of biogas can cause corrosion aggressiveness towards biogas network elements which has direct contact with biogas.
Filter bed has been developed in order to combine high efficient siloxanes removal (over 95% efficiency) with H2S reduction. Only application of properly selected activated carbons can assure expected technological effect.
Siloxanes removal filters can also be insulated and located outside the buildings.
