Untreated biogas can cause serious, or even permanent damage to systems such as boilers, cogeneration systems or biogas upgrading systems, which costs money.
The energy-efficient BIDOX® guarantees that all treated biogas will contain low levels of H2S, reducing the operating costs of biogas processing systems, because removing H2S does not require any chemical additives.
Wherever biogas is produced or used, you will find a biogas treatment system that either increases gas pressure, desulphurises or dries the gas to condition the gas in such a way that it can be used in a boiler, cogeneration system, engine or green gas upgrading system.
BIDOX® systems can be used at biogas and landfill gas installations, treating gas with H2S concentrations up to 10,000 ppm.
The sulphur-containing biogas is treated with aerobic bacteria in a biological gas scrubber, removing H2S under aerobic conditions. A small amount of the washing water is discharged from the BIDOX®, being fed into an existing wastewater treatment system, or being used as a diluted sulphuric acid or herbicide. The bacteria in the BIDOX® require only a small amount of trace elements and minimal aeration, resulting in low operating costs! Nutridox® contains the perfect mix of trace elements. The open gasket material and optimised design help prevent blockages in the BIDOX®.
The BIDOX® is characterised by:
- Low operating costs;
- Biological process, requiring no chemicals.
