Merus programs the carrier material to carry active oscillations. These active oscillations are steadily emitted into the fluid to be treated by means of the Brownian Movement. Water is capable of storing these oscillations and passing them on. In water the active oscillations encounter the natural oscillations of substances contained in water, for example those of rust, and interfere with these. Thus the entire oscillation pattern in water is influenced. Thereby diverse alterations are achieved. For instance trivalent iron (as in Fe2O3, which is rust) is changed to the effect that it reacts differently with oxygen. Lime does not solidify as quickly anymore and is flushed out continuously with the normal flow.
