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 solenoid.

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.  

Thus, 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 the fluid.

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 Force. The 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
  • Antifreeze
  • Oil, gasoline, diesel fuel
  • Animal waste slurry
