Based in Lucens, Switzerland, SONATEC develops and assembles salt-free water-treatment equipment, including its NATEC devices, through a precision-mechanics workshop operated by Sergio Silva. The company says its system emerged from 10 years of study at EPFL and 45 years of continuing development, using magneto-hydro-dynamic technology without electricity or chemicals. SONATEC’s equipment is offered for homes and industry and carries a 10-year warranty.
