“Proteus,” a new device for application of coagulants directly to sediment during its controlled resuspension

Abstract

One basic problem in the restoration of lakes and other waterbasins is limitation of the fraction of bio-available phospho-rus in the water volume. In practice the most frequentlyapplied method is phosphorus precipitation from the watervolume, with the aid of 2 basic coagulants: compounds ofiron, chloride, or sulphate; and aluminium compounds, mostoften sulphate (Burley 1998, Hansen et al. 2003, Klapper2003).
