The purpose of the work is to study the physicochemical regularities of the baromembrane processes of water purification with the processing of the obtained concentrates. Methods of investigation: laser diffraction method, photocolorimetry, spectrophotometry, titration analysis, potentiometry, catalytic incineration method. The main results - physicochemical regularities of baromembrane removal of humic acids by dynamic membranes on the basis of hydroxy compounds of aluminum and iron, fluorides and phosphates are established. It was shown that the maximum lagging capacity of dynamic membranes for humic acids is observed at pH 8.8 and the use of dynamic membranes from iron hydroxide and is 96.1% in TOC, while the color of the solutions is reduced by 98.7%. The expediency of using ceramic microfiltration membranes from clay minerals for purifying sewage with high and high turbidity is shown. The mechanism of microfiltration is established. The concentration limits of effective use of nanofiltration for defluorination and dephosphating of water with the production of permeates, which meet the requirements of the BPC for fluorides and phosphates, respectively, for drinking water and sewage are determined. A method of processing of formed baromembrane concentrates with the removal of valuable components from them is proposed. Application area - water treatment and water treatment.
