Description

This standard describes sodium aluminate (Na2Al2O4) in both liquid and solid form for use in the treatment of potable water, wastewater, or reclaimed water. Sodium aluminate according to this standard is a combination of sodium oxide (Na2O) and aluminum oxide (Al2O3) with sufficient excess causticity (sodium oxide) for stabilization. It can be referenced in documents for purchasing and receiving sodium aluminate and can be used as a guide for testing the physical and chemical properties of sodium aluminate samples. The stipulations of this standard apply when this document has been referenced and then only to sodium aluminate used in the treatment of potable water, wastewater, or reclaimed water.
