Ecological Systems and Devices Annotation << Back Flocculent’s influence on ability to live of microorganisms of actived sludge in aerotanks Potapova L.V., Vladimtseva I.V., . Navrotskii A.V., Kolotova O.V. It is established, that on stages of dewatering deposit of active sludge which is realized with use flocculents, there is a real opportunity of hit flocculent in a filtrate due to its adsorption on particles, past through the filter. Threshold concentration of some flocculents, causing inhibition growth of biomass of microorganisms actived sludge is determined. Recommendations for the decision of a problem of minimization of influence flocculents on microorganisms of active silt are given.
