  2. Advanced oxidation process - Wikipedia

    en.wikipedia.org/wiki/Advanced_oxidation_process

    Although oxidation processes involving ·OH have been in use since late 19th century (such as Fenton's reagent, which was used as an analytical reagent at that time), the utilization of such oxidative species in water treatment did not receive adequate attention until Glaze et al. [1] suggested the possible generation of ·OH "in sufficient ...

    en.wikipedia.org/wiki/Supercritical_water_oxidation

    Supercritical water oxidation (SCWO) is a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point. Under these conditions water becomes a fluid with unique properties that can be used to advantage in the destruction of recalcitrant and hazardous wastes such as polychlorinated biphenyls (PCB) or ...

    en.wikipedia.org/wiki/Wet_oxidation

    The oxidation reactions occur in superheated water at a temperature above the normal boiling point of water (100 °C), but below the critical point (374 °C). The system must be maintained under pressure to avoid excessive evaporation of water. This is done to control energy consumption due to the latent heat of vaporization. It is also done ...

  6. Oxygenated treatment - Wikipedia

    en.wikipedia.org/wiki/Oxygenated_treatment

    With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers.

  8. Girdler sulfide process - Wikipedia

    en.wikipedia.org/wiki/Girdler_sulfide_process

    Demineralised and deaerated water is fed to the cold tower where deuterium migration preferentially takes place from the hydrogen sulfide gas to the liquid water. Normal water is fed to the hot tower where deuterium transfer takes place from the liquid water to the hydrogen sulfide gas. In cascade systems, the same water is used for both inputs.
