Impact of Electromagnetic Fields on Gypsum and Silica Scaling in Reverse Osmosis.

This engineering study evaluates electromagnetic field (EMF) treatment as a nonchemical method to control gypsum and silica scaling in reverse osmosis using synthetic brackish water and real RO concentrate. It reports EMF altered gypsum crystal morphology to form a more porous scale that was easier to remove with…

Effects of Corm Treatment with Cold Plasma and Electromagnetic Field on Growth and Production of Saffron Metabolites in .

This study assessed pre-sowing treatment of saffron corms with cold plasma, vacuum, and an electromagnetic field (5 min) and measured effects on sprouting, growth, and stigma metabolites. EMF treatment did not affect corm viability and showed neutral or slightly positive growth effects, including increased flower…

Electromagnetic fields for biofouling mitigation in reclaimed water distribution systems.

This experimental study evaluated electromagnetic field (EMF) treatment as a chemical-free approach to mitigate biofouling in reclaimed water distribution systems. The authors report that EMFs altered biofilm bacterial communities, reduced diversity, disrupted co-occurrence network structure, and inhibited biofilm…

Mitigation of biofouling using electromagnetic fields in tubular heat exchangers-condensers cooled by seawater.

This paper describes an engineering application of electromagnetic field (EMF) treatment to mitigate biofouling in seawater-cooled tubular heat exchanger-condensers. After allowing a biofilm to stabilize, EMF treatment was applied and was reported to precipitate dissolved ions and contribute to partial…
