Treated floc curtains

Abstract

An apparatus and method are provided for removing ultra fine sediment suspended in water where the apparatus includes a sheet of open weave textile material, such as jute, that has a polymer flocculant applied thereto to provide a floe curtain for the water to flow through such that the suspended sediment can contact the flocculant and precipitate out of the water. The sheet comprises a top edge and a bottom edge with a top border disposed along the top edge of the sheet and a bottom border disposed near the bottom edge of the sheet. The top border comprises a first plurality of spaced-apart grommets disposed therealong. The sheet further comprises a geotextile tube disposed between the bottom edge and the bottom border. Two or more floe curtains can be placed in a spaced-apart configuration in the water to provide stages of successive filtering as the water flows through the floe curtains.
