The main factors affecting the physicochemical properties of microfiltration ceramic membranes based on natural quartz sand were studied. It was found that samples of large-porous ceramics with a content of 11.0 wt. % of the aluminosilicate binder and 10.0 wt. % of the burning additive are characterized by average pore size of 22±3.02 µm, water capacity of 54±5.0 m 3 /(h×m 2 ×bar), and tensile strength of 9.0±0.6 bar. The optimal conditions for membrane layers coating were determined, which allowed obtaining microfiltration ceramic membranes with average pore size of 2.3±0.2 µm, water capacity of 26±1.0 m 3 /(h×m 2 ×bar) and tensile strength of 6.5±0.3 bar.
