    The aim of this contribution is to investigate aggregation efficiencies when a fluidised layer of granular material (FLGM) is applied for a treatment of surface water with high DOC (Dissolved Organic Carbon) and low alkalinity in pilot size operation. It was established that FLGM can be effective for agitation of a system using destabilised particles with the aim to a form readily separable suspension. An aggregation efficiency of the FLGM reactor was evaluated by degrees of destabilization and aggregation of the particles of impurities. The maximal separation efficiencies of the pilot plant after filtration attained φAl = 0.96 and φDOC = 0.73. These values exceeded not negligibly the ones reported for the conventional aggregation processes.

    Příspěvek se zabývá vlivem vysokých intenzit agregačního míchání na separovatelnost suspenze filtrací při úpravě vody s v DOC a nízkou hodnotou KNK4.5. Jako míchací element byla použita fluidní vrstva zrnitého materiálu. Byla zjištěna vysoká míra agregace znečišťujících příměsí, která se pozitivně odrazila na účinnosti separace agregátů pomocí filtrace.
