Hydrogen sulphide contaminates biogas streams and in high concentrations can become toxic to digester health when in solution with sulphuric acid (inhibiting methane production if not treated in time). OMEX Environmental has introduced its Active Fe range to address these issues.
Following a high market demand for OMEX Environmental to supply a product that would help overcome all issues associated with traditional hydrogen sulphide deterrents, but also provide an effective solution for the hydrogen sulphide as a problem itself, the firm launched the Active Fe range.
“Further to laboratory- and field-testing of products, customers suggested we develop a range of powdered, non-hazardous, reactive iron-compound blends,” said the firm. At the time, this was a unique product for the market and since then it has managed to shift the mentality around handling the issue of hydrogen sulphide in anaerobic digestion processes.
The Active Fe range consists of three products, each one with unique abilities suited to its intended application:
• The Active Fe33, which is a fast-reacting product originally intended for digesters with low retention times.
• The Active Fe43, which is a more moderate-reacting product but with a set of unique properties that show monitorable effects in a short space of time.
• The Active FeMAX, which is a slower-reacting product, very high in iron concentrations.
All three products aim to achieve the same dual-purpose result: reduction of hydrogen sulphide and augmentation of the available nutrient-iron levels in the digester.
OMEX Environmental says it supplies this range of products as a non-hazardous, cost-effective solution for optimising the performance of anaerobic digestion plants and, amongst the other products in the portfolio for the biogas sector, fully supports it technically with a dedicated team and an effective laboratory support service.
