Waste water / Sewage treatment

Ozone (O3) is a strong oxidizer and can be particularly effective for cleaning aqueous waste streams. It is sometimes used as a pretreatment method, or to disinfect wastewater after biological treatment. It oxidizes a wide range of organics, (i.e. it can destroy cyanide wastes and phenolic compounds, and is faster acting than alkaline chlorination.) Plus, unlike chlorine, ozone doesn't generate toxic ions in the oxidation process. Oxidation and volatilization of organics, Control of algae and associated compounds, Destabilization (micro-flocculation) of certain types of turbidity, Removal of color-causing compounds, Oxidation of iron and manganese, Very short disinfection times, and Partial oxidation of organics for subsequent removal by microorganisms. Ozonation elevates the dissolved oxygen (DO) concentration of the effluent. The increase in DO can eliminate the need for reaeration and also raise the level of DO in the receiving stream.
