Wastewater Odour and Corrosion Control
Wastewater Odour and Corrosion Control

In aerobic systems, there is some direct oxidation by permanganate and the resulting ,manganese dioxide, further catalyses the reaction. The danger posed by corrosion as a result of hydrogen sulphide gas converting into sulfuric ,acid, may appear less immediately, but unchecked, has the potential to cause calamitous, corrosive damage to pipes and other equipment, which in turn exposes the ...

Aeration is also used to oxidize soluble iron ,and manganese, (found in many well waters) to insoluble precipitates. Aeration is often used to reduce the carbon ,dioxide, liberated by a treatment process. For example, ,acid, may be fed to the effluent of sodium zeolite softeners for boiler alkalinity control.

oygen. Oxygen is one of the most abundant elements found in Nature. In its molecular form O 2, oxygen or "dioxygen" is a colourless gas that is relatively insoluble in water (see characteristic constants of gases).. As demonstrated by the oxidation reduction equations, the oxidising capacity of oxygen is heavily dependant on pH and low compared to other oxidants used.
