Australia’s $40 billion of concrete sewage infrastructure, if left untreated, could corrode away in 8 years from sulphide attack.
Concrete sewer manholes are highly prone to corrosion due to acid attack. The corrosion mechanism is fairly simple:
Generation of H2S in sewer lines fills up the Manhole;
Oxidisation of H2S to H2SO4 by auto oxidation reduces pH;
Sulphide Oxidising Bacteria (SOB) form colonies as pH drops;
Convert H2S to H2SO4 (sulphuric acid) = corrosion of manhole.
One of the solutions to stop corrosion is by spraying PROTECTA-Mag™ (Magnesium Hydroxide coating) on the surface of concrete sewers.
PROTECTA-Mag is 7 times cheaper than other available technologies over the life cycle of the asset and does not require flow diversion or man entry for application.
