Our paper presents the results of research on utilization of after-centrifugal silts (AC-silts) from pro­cessing technical fats of animal and vegetable origins. The aim of the research was to compare two methods of fat recovery from AC-silts: dispersed (induced) air flotation (IAF) and hydrogen peroxide-enhanced dispersed air flotation (OxIAF). To realize this task a flotation system was constructed, which enabled com­plex testing of the method and the determination of parameters essential for the process. The installation of the output up to 10.0 m3-day4 was equipped with AC-silt storage-averaging tanks, a flotator, a centrifuge for separating fatty fractions and a set to process after-flotation residuals. The solution permits more than 50% recovery of fats from AC-silts. The residuals, mainly water-protein suspensions, may be considered as substrates to produce material of fertilizer properties.
