FIELD: process engineering.
SUBSTANCE: invention relates to treatment of contaminated acids, alkalis, and water, and to methods of producing ceramic filters. Ceramic filter comprises set of porous ceramic rectangular plates with through channels. Plate width t-to-length L and plate thickness h-to-channel size ratio is selected subject to relation t/L=0.46-2.0, d/h=0.65-0.9, while center-to-center distance A between channels is selected subject to A=(0.8-1.7)d.
EFFECT: chemically stable large-size high-efficiency filter plates, simplified production method, heat savings.
