Abstract

The present invention is directed to a pulse control unit for generating a signal comprising a base waveform in combination with one or more auxiliary waveforms and combining these into a single output. The frequencies are determined by a specific targeted component to be removed from a fluid. More sophisticated pulse control units can deal with multiple targets, either or both grouping and alternating the signal combinations for each target component to reduce signal interference. The output can be fed to a radiator set in a vessel through which fluid passes so that the fluid is subjected to a radiated field based on the output from the pulse control unit. The result is the promoted or enhanced precipitation or coagulation of target components from the fluid. The invention extends to fluid treatment apparatus comprising such a pulse control unit, and methods of fluid treatment. A preferred fluid for treatment is water.
