Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a controversial method of supposedly reducing the effects of hard water by passing it through a magnetic field, as a non-chemical alternative to water softening. There is a lack of peer-reviewed laboratory data, mechanistic explanations and documented field studies and erroneous conclusions about their efficacy are based on applications with uncontrolled variables. Magnetic water treatment is regarded as unproven.〔 There are, however, some studies which have claimed significant effects and proposed possible mechanisms for the observed decrease in water scale.〔 〕 ==Effectiveness== Vendors of magnetic water treatment devices frequently use pictures and testimonials to support their claims, but omit quantitative detail and well-controlled studies.〔 Advertisements and promotions generally omit system variables, such as corrosion results or system mass balance analyticals, as well as measurements of post-treatment water such as concentration of hardness ions or the distribution, structure, and morphology of suspended particles.〔 〕〔 〕〔 〕〔 〕〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Magnetic water treatment」の詳細全文を読む スポンサード リンク
