Possibilities of Flotation Plant’s Upgrading with Use of Hydro pneumatic system of aeration for Activated Sludge’s Thickening

Abstract

There were considered possibilities of flotation plants’ upgrading with application of hydro pneumatic system of aeration for activated sludge’s thickening. There was demonstrated that in flotation plans with pneumatic system of aeration, used for manufacturing of fodder hydrolytic yeasts, could be made substitution for hydro pneumatic system with receiving of sufficient efficiency for practical purposes. There were pointed ways of intensification of flotation process for activated sludges’ thickening by means of cationically active flocculants.
