Abstract

The conducted research concerned the effect of a magnetic field (MF) on the removal of iron compounds. The tested process was filtration through a quartz sand bed with a grain size of 0.4–0.8 mm. Another examined material was activated alumina. The obtained results proved that the MF had a significant impact on the efficiency of iron removal from a water filtrated trough than activated alumina. It was proven that the effect of the magnetic field on the filtration process using other filtration materials, was insignificant.

Highlights

  • The magnetic field (MF) is a physical process whose influence on different liquids is examined by researchers in many scientific centers

  • The experiments explored the effectiveness of iron compound removal in the magnetic field-assisted filtration process through quartz sand and activated alumina

  • The first column of each pair of devices filled with the same filtration material was the control stand and another one was for magnetized samples

Summary

Introduction

The magnetic field (MF) is a physical process whose influence on different liquids is examined by researchers in many scientific centers. The common process used for separation of particular components from the water is filtration and adsorption. During those processes, water contaminants are retained on the outer surface of filtration material grains or inside their pores. One of the inorganic sorbents rarely used for removing the contaminants present in water is activated alumina (Al2O3) [5,6]. This material is not chemically inert and has amphoteric properties. The experiments explored the effectiveness of iron compound removal in the magnetic field-assisted filtration process through quartz sand and activated alumina. Obtained results proved that it is possible to apply a constant external magnetic field as an additional elementary process for improvement of the efficiency of filtration and adsorption
