The Triangular Wave Deposit Control System produces a self-tuning
induced molecular agitation (STIMA). This text briefly reviews the
physical laws behind the STIMA.
All induction coils use a solenoid wrapped
around a pipe. Most of them simply apply a DC or AC current to
produce a magnetic field inside the pipe. A wire is wound on the outside wall of the pipe; thus forming a
When there is a current flowing in the solenoid coil, a magnetic field
is produced, which is the result of Ampere’s Law. The right hand rule
determines the direction of the magnetic field inside of the pipe. The
strength of the magnetic field is proportional to the product of the
current, I, and the number of turns of the coil in the unit length, n. B =
monI, where B is the magnetic field vector [ Wb/m2 or Ns/Cm].
Note that the magnetic field strength produced by a solenoid coil is
much smaller than that of permanent magnets. For example, for a DC current
of 100 mamps with 1100 turns per meter, the magnetic strength is only 1.3
gauss ( with the permeability of free surface of 4p * 10-7 Wb/Am).
Considering that a permanent refrigerator magnet that holds notes has a
strength of 100 gauss; the magnetic field produced by the solenoid coil is
extremely small. If one recalls that the strength of permanent magnets
used in water treatment is on the order of 5,000 gauss, one can easily
conclude that the electronic deposit control technology does not depend on
the strength of the magnetic field at all.
The Triangular Wave Deposit Control System changes the direction of the
current in the coil approximately 2,000 to 7,000 times per second.
the magnetic field inside of the pipe also changes 2,000 to 7,000 times
per second. This step is called the frequency modulation. The frequency
modulation is necessary, because one does not know the natural frequency
of the fluid, a priori. The natural frequency of the fluid depends on its
viscosity and temperature. Since it is extremely difficult to determine
the natural frequency of the fluid, in situ; one needs a "self-tuning
method, which automatically tunes the system to the natural frequency of
To change the direction of the current, the Triangular Wave
Deposit Control System uses a pulsing current. When the current changes
polarity from, for example +100 mamps to -100 mamps, the corresponding
magnetic field changes its direction from the right to the left. When the
magnetic field varies with time, an induced current is produced inside the
pipe, according to Faraday’s Law.
By Faraday’s Law the induced electric field vector is a function of
the time rate of change of the of the magnetic field and the
magnitude of the magnetic field strength. Since the Triangular Wave
Deposit Control System yields more than enough induction, even with a
small magnetic field strength, there is no need to increase to a greater
magnetic field strength. The fact that the Triangular Wave Deposit Control
System does not generate (use) a strong magnetic field strength is of
practical importance due to the growing concern of the adverse
physiological effect of the strong magnetic field strength on humans.
When a charged particle, with charge q, moves through electric and
magnetic fields, the particle experiences the Lorentz Force. (This is the
same force that causes the movement of an electron beam in a television).
F = qE + q(V * B)
F = Lorentz Force vector [N], and V is the particle velocity vector
[m/s]. The Lorentz Force consists of the electric force (i.e., the first
terms in the right side of the equation) and the magnetic force (i.e., the
second term). The electric force is independent of motion of the charge,
whereas, the magnetic force depends on the velocity of the charge. (Magnet
treatment systems need fluid motion to get the Lorentz Force.) Note that
the Lorentz Force is the force experienced by a charged particle passing
in an electromagnetic field under a steady state condition.
What happens in the Triangular Wave Deposit Control System is similar
to, but is a very different phenomenon from the conventional Lorentz
Triangular Wave Deposit Control System causes "induced molecular
agitation". The charged particles in the fluid (water molecules
themselves, scale ions, colloids, bacteria, and algae in water) experience
molecular agitation as they pass through the pipe section with the
Triangular Wave Deposit Control System. The induced molecular agitation is
caused by the polarity change, the frequency change, and the amplitude
change discussed previously.
The combination of polarity, frequency, and amplitude change give the
Triangular Wave Deposit Control System the ability to treat a wide variety
of fluid streams:
- Water with scale particles, bacteria, algae, and colloids
- Water and oil lubricating fluid
- Oil, gasoline, diesel fuel
- Animal waste slurry
