Ovcharenko Institute of Biocolloidal Chemistry NAS of Ukraine popup.description1 The purpose of this project is a comprehensive study of the process of sorption of petroleum products of various origins dissolved in water, the determination of the most effective clay sorbents and the development of technology for their separation from water by flocculation and flotation methods. popup.description2  The process of separation of ultradisperse clay suspensions by ultraflocculation and sedimentation was studied. Bentonite clays from four deposits of Ukraine were selected as samples: Neporotovsky, Ilnytsky, Dashukovsky, Gorbsky. Products of BASF (Germany) were selected as flocculants: Magnafloc 1011, 155, 5250 and E10. The efficiency of the ultraflocculation process was measured using the UFT-TFS-029 device manufactured by Turboflotservice (Kyiv), which contains a Couette flocculant and an electronic analyzer of the average floc size. By adjusting the speed of rotation of the flocculant rotor, it was possible to change the shear rate in the volume between the rotor and the stator in the range from 300 to 3000 s-1. Additionally, an original mini-thickener (which we developed and manufactured as part of the scientific topic) was connected to the outlet of the device to measure the sedimentation rate of flocs of the suspension that underwent the ultraflocculation process in the device. It was found that the most universal flocculant that effectively acts in the ultraflocculation of all samples of clay suspensions is Magnafloc 5250, and the optimal shear rate at which the maximum floc sedimentation rate is 2000-3000 s-1.
