- Abstract
Introduction. The aim of the work was to build a mathematical model of the process of suspension filtering on the filter with self-purifier filter element that is designed as a cylindrical compression spring. Materials and methods. Research of the filtering process was performed on the filter with self-purifier filter element. As a studied suspension the milk whey was used, obtained in the production of cottage cheese. The concentration of the dispersed phase in the milk whey was defined by centrifugation of samples followed by further drying sludge in a drying oven. Results and discussion. The gained mathematical model is based on the model of the filtering process with clogging each pore with the individual particle. The model takes into account that not all of the dispersed phase particles that are larger than the width of the filter holes, will clog them, but only their particle that is directly proportional to the ratio of living area to the total area of the filter surface. The mathematical model allows to determine the length of the filtering process based on the volume of suspension, and to set the rational period between regenerations of self-purifier filter element. Comparing the parameters obtained by mathematical modelling with the real process of filtering milk whey indicates that the mathematical model adequately reflects the separation process of suspension on the filter with self-purifier filter element with the volume of filtrate from 0 to 5 m³ per 1 m² filter surface - the average relative deviation of the results obtained with the help of the mathematical model of the experiment is 11%. Conclusions. The mathematical model can be applied in calculating parameters of the process of suspension filtering on the filter with self-purifier filter element.
