Silane, e.g. trimethylsilane, is a strong reductant and can only exist as such in parts of activated sludge plants where a low redox potential exists, i.e. the anaerobic stages of the process. However, it became apparent that an oxidised variety of silane is present in wastewater, i.e. the AOS which is a strong
