Peculiarities of purification of natural water from iron compounds using ceramic membranes

Abstract

The paper deals with the issues of natural water purification from iron compounds. A comparison of polymeric and ceramic membranes is given. During the experiments, ceramic membranes modified with titanium and completed in a filtering element were used. Experiments on filtration of simulated solutions of ferric iron have been carried out. The dependence of the permeate flux on time for various initial concentrations of ferric iron and the dependence of the working pressure on the volume of the filtrate for various initial concentrations of ferric iron, at a constant filtration rate is shown. It was found that the residual concentrations of iron (III) compounds, regardless of the experimental conditions, met the regulatory requirements and did not exceed 0.3 mg/l. Based on the results obtained, flow diagrams of ultrafiltration units based on ceramic membranes were proposed.

“…This research showcases effective techniques but encounters challenges related to high costs. In [14], author study ceramic membranes for removing iron compounds from natural water, offering a noteworthy solution for this specific issue. Despite the merits of these individual methods, they grapple with either limited scope or cost-effectiveness concerns, also the broader issue of water hardness in milk recombination processes is still multifaceted problem.…”
