In sewer systems, when hydrogen sulfide gas is emitted from sewage and meets condensing
moisture, the process can form sulfuric acid that rapidly corrodes the concrete in a sewer tunnel. This is known as the microbially induced corrosion, which poses a severe threat to the sustainability of concrete in sewer tunnels. Andrew discusses a system developed to prolong the service life of water treatment works.
