This page provides information on aluminum (Al) and iron (Fe) compounds and their application in stormwater management.

Overview and description

Iron oxides and hydroxides are chemical compounds composed of iron and oxygen. They are widespread in nature, play an important role in many geological and biological processes, and are widely used in many applications, including use as ores, pigments, and catalysts. Iron oxides may occur with iron in a reduced state (FeII), oxidized state (FeIII), or a mixed state.

Aluminum oxides or are a group of inorganic compounds with formulas including aluminum (Al) and oxygen (O). The most common form, aluminum oxide, has the formula Al2O3, but other forms include Al2O and AlO. Aluminum oxides are primarily used in the manufacture of aluminum metals.
