Aluminium is a metal and is widely used as a coagulant in water treatment. Typical applications include the monitoring of aluminium residuals in drinking water, post clarification aluminium levels in the water treatment process and also effluent discharge from industrial processes.


Online aluminium monitors use colorimetry to determine the aluminium concentration in water. Typically they use Pyrochatecol violet (PCV) chemistry which is free from fluoride interference unlike other colorimetric methods such as Eriochrome R.
