Superconducting Magnetic Filter: Performance, Recovery, and Design

Abstract

Due to the development of superconducting magnets, the magnetic filtration process is now undergoing its biggest evolution since its conception. In Japan, the first industrial superconducting magnetic filter has been successfully applied for factory wastewater treatment. Much effort in both theory and practice is needed to further contribute to the new developments of this high gradient magnetic filtration process. In this substantial review, we have collected the most important theoretical and practical data about magnetic filtration, its recovery and design to establish a good framework for further development of this amazing technology.Index Terms-Electromagnetic processing of materials, high gradient magnetic field, superconducting filter, wastewater treatment.

High-Gradient Magnetic Separation of pollutant from wastewaters using permanent magnets

“…From these results, using Eq. (18) and summing on the three populations, the capture efficiencies of the filter in the various experimental conditions are calculated and are shown in Table 5. These basically experimental results have been checked with Eq.…”

“…The DBFs are usually described with simple relations for the capture efficiency in which the characteristic parameters are derived using one of the following approach: empirical model, stochastic model, network model, trajectory analysis. The most used models are based on the trajectory analysis for the estimation of the capture efficiency [18]. In the trajectory analysis the problem is usually oversimplified to gain an analytical solution for both the velocity and the flux density field.…”

Water purification using magnetic assistance: A review

“…Many important performance equations of magnetic separator including other interacting forces can be referred from the works of Watson [46], Lubrowsky [47], Clarkson [48], Uchima [49], Birss [50], Sandulyak [51], Abbasov [52] and Eskandarpour [53]. Table 1 summarises a qualitative picture of the variables of impurities and magnetic separators.…”

Towards a model of chain-by-chain magnetization of a granular medium: a variant of magnetic diagnostics of chains of spheres

“…Используя экспериментальные данные Φ (рис. 2), нетрудно получить данные магнитной индукции B в каждой из квазисплошных сердцевин радиусом r и сечением πr 2 -как B = Φ/πr 2 , а также данные магнитной проницаемости µ соответствующих сердцевинкак µ = B/µ 0 H = Φ/πr 2 µ 0 H, где µ 0 = 4π · 10 −7 Гн/ммагнитная константа. Установленные для разных (по r/R) сердцевин данные B и µ в виде семейств зависимостей B и µ от H, а также полученные из них не менее информативные семейства зависимостей B и µ от H от r/R (при разных H) показаны на рис.…”
