Use of Active Silt after Preliminary Floatation Processing as Bioflokulyant

Abstract

In work options of preliminary handling of active silt with its subsequent use as a bioflokulyant are considered. It is shown that efficiency of use of active silt increases using its preliminary handling allowing to give active silt in the condensed type and also by its activation with addition of reagents. Examples of a floatation condensation of active silt by a floatation method and with use of the chemical reagents having properties of coagulants and flokulyant are given. The received results give the chance to recommend options of reagent and floatation handling of active silt before use it as a flokulyant. In this case volume expenses of use of active silt as a bioflokulyant by 1,5–3 times are cut down.
