The function of the lamellar settler is to remove suspended semi-heavy and heavy particles (grit, clay and lime) from the water. These elements hinder subsequent treatment by producing deposits in hydraulic conduits, piping and channels and causing abrasion to pump impellers and equipment etc.
In the decanter it is where solids are separated from the treated water. This separation is done by simple gravity, being solid, higher density, which settle to the bottom.
