| Abstract: | Investigated are main regularities of the process of defluorination of water by nation-made ceramic membranes from clayey minerals, modified by a dynamic layer from aluminum hydroxycompounds and demonstrated its high efficiency. It was proposed to use specified membranes for defluorination of water to MAC standards in drinking water at the initial concentration F– up to 22.0, Al3+—4.0–6.0 mg/dm3 in the additive forming the dynamics, pHini 6.5–7, P—1.0 MPa. |
