CaCO, scale formation on pipe walls and heat exchange equipments in industrial or domestic water processes is a serious problem. A great number of experimental researches on the prevention ofthe CaCO3 precipitation process by magnetic field have been carried out. The efforts to understand the effect of the magnetic field on the CaCO, precipitation are still being developed In this research, Na2CO, solution was magnetized by 5200 gauss permanent magnet before mired with CaCl2 in ...

Anti scale magnetic treatment is a hard water treatment method using magnetic field to prevent (CaCO3) scale formation. This method has along and controversial history due to its unclear result of its mechanism and effectiveness. The results of researches, hypothesis, or explanations given by researchers were still partial and didn't satistfy yet in answering the magnetic phenomenon. There were three mechanisms which were suggested: ion mechanism. particle mechanism and Lorentz force eject. Hard water contain ...

Penelitian ini membahas perilaku presipitasi CaCO3 dalam air sadah dibawah pengaruh medan elektromagnetik beserta aplikasinya dalam pengolahan air sadah dan pencegahan kerak. Hasil penelitian membuktikan bahwa medan elektromagnetik mempengaruhi interaksi hidrat ion dan interaksi ion serta presipitasi CaCO3 pada pola aliran fluida dinamik.
Elektromagnetisasi larutan NaHCO3 dan CaCl2 dapat meningkatkan presipitasi CaCO3 dengan sifat deposit yang lebih mudah lepas dari dinding. Peningkatan presipitasi secara signifikan terjadi pada konsentrasi, lama sirkulasi dan laju alir tertentu. Hasil ...
