Consequently, the third step of ,wastewater, treatment includes biological ,nitrogen removal,. This means a combination of nitrification and denitrification processes, carried out by various micro organisms. Nitrification means ammonium ,oxidation, from protein decomposition processes by bacteria, and subsequent conversion to nitrates.

Removal of iron – OxyPure is effective in oxidation and precipitation of iron, by oxidizing the iron to form dense solids, which are easily removed. Iron could otherwise discolor water, spot laundry, stain plumbing fixtures, and if bacteria were to grow, an abnormal taste, odor and biofouling could develop in the water system.

Fe2+, Sb(V) ,removal, by the AIM could be greatly enhanced, in which a treatment of 50 mg/L with 10 g/L AIM could decrease Sb(V) to below 6 ug/L, the EPA drinking water maximum contaminant level (MCL). Sequential dosing test showed that such high ,removal, of Sb(V) could be sustained in a continuous flow treatment system.
