Effect of Some Process Parameters on the Separation of the Dispersed Ferrous Impurities Using Cycled Electromagnetic Filter

摘要

Electromagnetic filters (EMFs) can be effectively used for the cleaning of both industrial and domestic disposals such as waste water having low concentration and micron size of dispersed particles that show magnetic characteristics. In this work, we investigated the effect of some parameters of the filtration process, external magnetic field density, size of the filter matrix elements, filter length, filtration velocity, viscosity of the suspension, and number of the cycle on the separation efficiency of micron-sized particles that can be magnetized in an external magnetic field. It has been found that filtration efficiency decreased with increasing filtration velocity and suspension viscosity. Furthermore, the filter matrix elements geometry, pH value of the medium, and number of the cycling processes affected the cleaning efficiency. Recycling the suspension to the filter body allowed the cleaning process to be made in a smaller filter size with a high quality factor.View full textDownload full textKeywordsDispersions, electromagnetisma, filtrationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01932690903224896
