The high efficiency of water purification processes from hydroxocompounds Fe(III) and Mn(II) by a microfiltration ceramic membrane of clay minerals is shown, and their main laws are determined. It is established that, with the initial concentration of Fe(III) up to ~ 170.0 mg/dm3, pH 5.0—7.5, and P = 1.0 MPa, water can be purified to MPC of iron in drinking water with a specific membrane productivity of 0.28 m3/(m2 · h). So, the high retention capacity of the membrane can be explained by the steric mechanism of its action, which is associated with the difference in the pore sizes of the membrane and the particles of Fe(III) hydroxocompounds formed in the indicated pH range. Purified from hydroxocompounds of Mn(II) to MPC, water was obtained at their initial concentration of up to 33.76 mg/dm3, pH 8.3—8.4, P = 1.0 MPa and the achievement of the specific performance of the membrane 0.27 m3/(m2 · h). To ensure the high efficiency of this process, it is necessary to premodify the ceramic membrane for ~ 55.0 min by hydroxîcompounds of Mn(II) in the water itself.
