Abstract

The depth detachment filtration with linear kinetics and an unregulated rate is considered in detail. A significant filtration rate is initially provided due to the suspension accumulation in the storage tank. The early and preparation stages are specially studied. The main interest is the final stage, during which the suspension is processed with a declining filtration flow rate. The technological analysis is carried out considering the limitation on the decrease in the filter performance. The hydraulic properties of the filter communications and variable head losses in them are taken into account. Mathematical modeling is significantly complicated due to the close relationship between the kinetic parameters and the filtration rate. An approximate solution is obtained with minimal errors for the general form of such relationship. An exact solution was obtained and a reliable calculation method developed based on it. The limiting storage tank height was evaluated, calculations of the filter run duration and applied optimization of the bed absorption properties were performed.
