Practical Assessment of Electronic Water Treatment for the Prevention of Fouling

Abstract

Fouling or scaling, i.e., the occurrence of deposits on tubes, heat exchangers, and other devices, is a common problem in industrial and domestic processes. Many anti-fouling techniques exist, both chemically and non-chemically. The efficiency of non-chemical methods is still controversial, although the use of these devices is already widespread in industry. In this contribution, a case study is presented in which the operation of such a device is demonstrated. The electronic water treatment device under study was connected to a 2 m-long copper tube immersed in a water bath with a temperature of 65°C. A short-term experiment revealed that the device did not alter the water chemistry and that locally, fouling was prevented by the device. However, the potential for fouling further downstream was not reduced. A long-term experiment further confirmed the findings of the short-term experiment showing that locally, the device has an anti-fouling action as a significant increase in weight was observed when the device was switched off and a significant decrease in weight was observed when the device was switched on.

Effect of magnetic treatment of mixing water on the behavior of cement-based materials: A review

“…Various techniques have been employed to treat mixing water in research, including mechanical, chemical, thermal, electrical, and magnetic treatment [9][10][11][12][13]. Many studies revealed that magnetic treatment, in particular, shows promising potential in activating the behavior of cementbased construction materials [19][20][21].…”

Optimizing of mathematical modeling of induced current for electronic anti-fouling system and estimate of system performance under different excitation signal

“…There are many researchers do a lot of qualitative researches based on the above-mentioned antifouling mechanism of EAF system [6][7][8][9][10][11]. But to the best knowledge, none of research works about controlling the induced electric field acted on the solution by EAF system have been done yet by now.…”
