OMEX Environmental is supplying a new non-hazardous iron powder product to the anaerobic digestion industry for the minimisation of hydrogen sulphide levels in a plant’s fermenter.
Biogas can often contain hydrogen sulphide which needs to be removed to avoid odour and corrosion issues occurring. The dissolved H2S in high concentrations can be toxic to the bacteria in the slurry which can inhibit the production of biogas and cause its composition to alter.
The presence of hydrogen sulphide in biogas also makes it corrosive to metal parts. Iron is subject to surface attack, although not major corrosion. However, the effect on non-ferrous metals in components such as pressure regulators, gas meters, valves and mountings, is much more serious as they are very quickly corroded.
Active Fe is designed to minimise hydrogen sulphide levels in the fermenter by binding it immediately during formation. Therefore allowing the AD process to occur uninhibited resulting in optimal biogas yields and methane content.
How does Active Fe help? OMEX Environmental summarises the benefits as follows:
• Easy to apply straight into the fermenter
• An effective measure in preventing acidification
• Non-hazardous compared to other iron products in the market
• Fast results
