Optimum Settings

I found the following to be the best or most optimum temperature electrode spacing, voltage, wave form, frequency, amperage, and electrode surface area:

Temperature: 70 degree F
electrode spacing: .2 inches
Voltage: 160 V DC
Frequency: 2 sec/cycle
(this can be simulated by interchanging the voltage on the electrodes every so often)
Wave form: square wave
Available current: 1 amp
electrode total surface area: .75/2 sq. in.

Observed effects:

• Voltage too high (Above 300 Volts) then the unit becomes dangerous and can't easily supply the current or amperage to keep the voltage up to where it needs to be to use any decent sized of silver electrode surface area. This is the problem I found with the high voltage units I borrowed, tested, and at first built. I had one commercial unit that supposedly used 30,000 volts. I measured 20 volts when it was in operation.

• Voltage two low (below 80 volts) and electrodes need to be too close for good water flow or the process is slow and inefficient.

• Low electric field gradient (electrodes too far apart) produces a low charge on the colloidal silver particle and it tends to drop out of solution sooner than it should. With wide electrode spacing the process takes so long that you pull as much silver out of solution as you put in, thus hard to get a high PPM. Gives a more metallic taste the lower the voltage used. The high voltage result doesn't have this taste as much. I observed the silver produced with low electric field gradients to produce more waste or black particles for every ounce of a given PPM colloid. This is probably because it took much longer to make.

• High electric field gradient (electrodes too close results in bridges of black silver oxide forming across the electrodes that shorts out the process. In other words it is hard to keep the flow of water between the electrodes. Needs constant agitation of the water between the electrodes. There is a possibility of the silver particle size to become larger as the electrodes get closer. However, I never found this to be true no matter how close the electrodes got.

• Available current needs to be enough to keep the voltage up during the full span of the process. If voltage drops too much then one gets into the low voltage effects. The needed amperage is related to the size of the electrodes. The more surface area the more amperage is needed to maintain the voltage once the solution gets a little silver in solution and becomes conductive.

• Agitating to keep the electrodes from shorting (due to bridges of black silver oxide forming) is necessary to use this medium voltage approach. Without agitation you can waist some silver.

I use the following general guide lines:

 

1.5 Min/oz will give a golden-yellow estimated to be well over 100 PPM

(voltage gets down to about 140 volts)

 

2.3 Min/oz will give a darker golden-yellow estimated to be well over 300 PPM

(voltage gets to a point the light bulb is glowing and pulsing constantly)
