Abstract

The present invention relates to a method and a system for desulfurization of biogas comprising of hydrogen sulfide. The method comprises the step of preparing a raw biogas and feeding the same to a scrubber tank (100), preparing bacteria and growing the bacteria inside a sphere shaped packing positioned in the scrubber tank (102), deploying bacteria into the aeration tank (103), and supplying oxygen to the aeration tank and the scrubber tank via a pump member (104). The resulting clean purified biogas then exits the scrubber tank (105).
