 Methods are described for flocculating and removing solids suspended in water using an inorganic component containing iron, aluminum, or a mixture thereof in combination with a tannin-based flocculant produced by reacting a condensed tannin with an amino compound and an aldehyde. The tannin-based flocculant is preferably the product of a controlled reaction in which the viscosity is monitored as an indication of suitable shelf life.
