Montgomery (1985) reported on a treatment for
H2S removal using a cascade tray aerator on the top of a
ground water storage tank. The process produced high
levels of turbidity and an offensive rotten egg odour.
The turbidity resulted from the oxidation of hydrogen
sulphide to elemental Sulphur (S0). The removal
efficiency was only 20% at ambient pH and
temperature and the remaining hydrogen sulphide was
oxidized by chlorine and sent to the storage tank. The
turbidity created by elemental sulphur interfered with
the disinfection process and created issues in the
distribution pipes.
