Operating principle

The waste stream is used to fluidise granules, typically quartz sand, in the reactor column. By adding iron and manganese and an oxidising agent to the wastewater, the metals are adsorbed on the granule surfaces and oxidised.

This is an ongoing process and the metal coating increases the diameter of the granules which must be replaced eventually.

These granules are the waste product of the process.They contain about 10% water and are easily dried and handled.
