Öğe Effect of operating parameters on magnetic filtration processes(Amer Chemical Soc, 2004) Künkül, A; Ekmekyapar, A; Akmil, C; Abbasov, TThe effect of operating parameters and the effect of the pH of the liquids to be cleaned on the magnetic filter performance in the filtration processes were investigated. The pH of aqueous suspensions containing ferromagnetic particulates was changed in the range of 3-10. The suspensions were prepared in our laboratory. The effect of the size of filter matrix elements (diameter of the ferromagnetic spheres) and filtration velocity on the filter performance was determined. The filter performance of the filter matrix composed of a mixture of different size spheres was also investigated. A magnetic filter performance above 60% was obtained with a filtration velocity of 0.07 m/s. It was observed that if the size of particles and the fraction of ferromagnetic particles in the suspension are varied in a short range, the effect of the initial concentration of corrosion products on the magnetic filter performance is negligible. The experimental results were compared with theoretical calculations and the data in the literature. Suggestions are given about choosing optimum values of the operating parameters for effective filtration of industrial fluids in magnetic filters.
