Περίληψη

Evaluation of aluminum coagulants to remove fulvic acid from water depends on the process of separating the precipitate from the liquid phase. Membrane filters are often used for this purpose. The degree of separation was found to depend on the filter pore size. Differences in removal efficiencies of up to 80% were observed when membrane filters with pore sizes of 0.45 and 0.10 μm were used for the solid-liquid separation. Membrane filters with a pore size of 0.45 μm under certain experimental conditions demonstrated deep-filter characteristics in the sense that in the initial steps of filtration, when the filter was clean, small particles were filtered through, but as the filter pores became clogged, the efficiency of the filter improved.
