Description
Summary:As part of the study of the possibility of using hydrodynamic water treatment for preliminary deferrization of artesian water before feeding it to a deep osmotic treatment unit. It was found that in the process of water treatment in a hydrodynamic device with constant air ejection, the complete oxidation of iron (II) compounds occurs. The influence of the volume of consumed air and the number of processing cycles on the efficiency of the deferrization process has been studied. Data were obtained on the distribution (size / ratio) of air bubbles in the fluid flow during its hydrodynamic treatment. Based on the results obtained, it was concluded that when hydrodynamic treatment is combined with ceramic ultra filtration membranes, the iron removal rate is 99%, while hardness salts, hydrogen sulfide and other pollutants are partially removed from the water, and complete disinfection occurs.
