ABSTRACT

In many industrial processes, it is necessary to separate the solid phase from water or an aqueous solution. Gravitational methods are often used for this purpose (beneficial energetically), e.g. a sedimentation process. However, due to the low efficiency of the classical sedimentation process, it is necessary to intensify this process, e.g. by means of a coagulation process or flocculation process. The effectiveness of the coagulation process depends on a number of factors: dose and type of coagulant, type and concentration of removed impurities, pH, etc. The paper reviews the influence of the parameters of the coagulation process on the efficiency of the suspension treatment process. The coagulation studies of a selected group of suspensions were carried out, with the determination the effect of the dose and the type of coagulant and the conditions of the coagulation process on the obtained sedimentation efficiency. The selection of a coagulant dose was carried out using a jar test and in order to determine the sedimentation efficiency, a sedimentation test was used.

Keywords: coagulation process, sedimentation, intensification
