The definition of the possibility of replacing frame filter presses with multi-patron filters with in-house-made cartridges of different porosity is considered. The purpose of the work is to determine the possibility of complete replacement of frame filter presses with multi-patron filters with cartridges of own production. Tasks: - selection of cartridge filter elements; - equipment adjustment. The most effective in operation are the filter elements SL 1016-30 (with pore diameters of 15 and 17 microns). They provide the lowest Kf-value (0.10 ÷ 0.11) and the highest capacity (up to 900 l/h).
