Water treatment device and water treatment method using the same

Abstract

In apparatus for pulsed electromagnetic field treatment of water, with spaced induction coils (16) mounted in a tube (15), where the field intensity is adjustable via the impulse frequency, the impulses are generated by a specific type of integrated circuit (IC) (2), connected to a 12 V current source and including e.g. a potential-controlled generator (3), ramp generator (4), counting component (5) and scanner (6). Apparatus for pulsed electromagnetic field treatment of water comprises at least two induction coils (16) mounted at the ends of a stretch of tubing (15), such that the field intensity is adjustable by controlling the frequency of the impulses, which are generated with an integrated circuit (IC) (2). The IC is connected to a 12 V current source and includes a potential-controlled generator (3), a ramp generator (4), a counting component (5) and a scanner (6) connected to a frequency limiter in the form of an externally adjustable potentiometer (7). In the IC the generator (3) is connected additively, as signal source, with the ramp generator; and the scanner (as frequency source) and counting component (as controller of the number of pulses per unit time) are connected with the ramp generator and signal outlet line. The signal line for the frequency- and potential-controlled sum signal of the the IC are connected with a transistor bridging circuit (9), as signal converter with an overall switching speed of at most 1 mu s per pulse. The signal outlet line of the bridging circuit leads via a counterstroke amplifier (10) and a potential-current converter (11) with a connected output network part (12) into an amplifier stage (13), which is adjusted for a potential amplitude of at least 20 V per pulse and is connected at the signal outlet side with the similarly oriented windings of the induction coils (16).

Description

technical field [0001] The present invention relates to a device for water treatment by means of electromagnetic field and a water treatment method using the device. At each end of a pipe with a certain length, a magnetic field is generated by a harness induction coil, and its magnetic field strength can be controlled by The frequency of the pulses produced by the generator is set and the intensity is controlled by a first converter with an associated potentiometer for controlling the water flow and a second converter for monitoring the hardness of the water, for the correlation of the volt-ampere converter Potentiometer, where the frequency change of the signal from the ramp generator is superimposed on the frequency of the signal generated by the generator, whereby the frequency control signal is generated, which is then superimposed on the signal from the volt-ampere converter to produce a signal exhibiting a cumulative frequency, The frequency from the low-frequency amplif...
