Constant Current Colloidal
The voltage source may be the same or higher as constant voltage generators at the beginning of the operation but the similarity between constant voltage and constant current generators diverges rapidly. As the current flow begins to increase with increased water conductivity, the "constant current" regulator begins to reduce the voltage in order to keep the current at the desired amount of flow. With the voltage being reduced in order to keep the current constant, the silver particle size remains uniform. As the water becomes very conductive, the voltage may be reduced to as little as 5 or 6 volts to maintain the desired current flow. With this type circuit, one may leave the generator connected to the electrodes and not worry that "runaway" will occur. You may leave the generator on until the strength of silver in parts per million (PPM) is reached and be assured the particle sizes are uniform and colloidal. Of course we are speaking of practical limits here. This is the secret of repeatable production of colloidal silver. Constant current equals constant size particles. Typically, CS made over 15 PPM will usually agglomerate. Walks With Hawks automatic generator (SG6 Auto) with stirring motor can make up to 20 PPM.
The proper color for colloidal silver water is clear. If it is clear and has a weak Tyndall effect, the particle size is as small as can be made. That is the best way to know you have colloidal silver water. Make it yourself and then you will know and see what we mean! The proof is in the clear color and the Tyndall effect. Of course you can also test it using the PWT meter to determine the total PPM. At Walks With Hawks Herbs we test our distilled water and also test our Colloidal Silver for PPM.
With our SG6 automatic generator you just set the dial to the PPM (parts per million) desired and wait until the unit shuts off and you will have the best colloidal silver that can possibly be made. It will always be crystal clear and have a weak Tyndall effect. You may observe this effect by directing a pocket laser beam or strong narrow flashlight beam through the liquid after the dispersion phase. The beam will be visible as the particles are evenly dispersed, allowing the light to reflect off them. This is called the Tyndall effect.
The bottom line is this: Make sure your CS is clear, and you will be getting the largest amount of individual silver particles per unit measure of water. As an example, 1 milligram of silver dropped into 1 liter of water is equal to 1 part per million by definition. If you could turn that 1 milligram into 1 million individual silver particles and disperse it in the water, the PPM is still 1. However you now have many more individual pieces of silver in the water to attack bacteria and viruses. If you could divide that 1 milligram of silver into so many pieces they barely reflected any light, then you would have the optimum amount of silver per unit measure of water. Typically those particles are about .001 to .005 microns in diameter. A micron is one millionth of a meter (or 26 millionths of an inch) so .001 microns is about 1/1000 of 1/1,000,000 of a meter. Pretty small particles indeed. Walks With Hawks generator typically produce particle sizes ranging from .001 to .005 microns. If particle size increases beyond that, the particles will begin to reflect light and the first color seen will be yellow. That is when you should stop making Colloidal. That is called agglomeration.
Another factor in colloid production is the surface area of the electrodes. If one uses wire as the electrodes as most manufacturers do, the surface area is quite small. As an example, 14 gauge wire, which is what most units are sold with, has a surface area of approximately .8 square inches if it is submersed 4 inches in the water. Two wires will give approximately 1.6 square inches of wetted surface area.
Our electrodes at Walks With Herbs are 4.21 square inches. This is 2.5 times the wetted surface area of 14 gauge wires. Therefore the current density of 14 gauge wires will be 2.5 times higher than the electrodes we use. What this means is, the amount of silver released using our electrodes will be so spread out over the surface of the electrodes, it will be releasing at a slower pace. If the silver is released more slowly, the particles are smaller. They will also be more uniform in size because of the constant current regulator and stirring. The result is a more uniform, small particle size colloid.
If one used a constant voltage source, such as the typical box with three batteries or a machine that uses a wall transformer to provide a constant DC voltage, the silver would begin to be ripped off the wire electrodes very quickly because of the high current density which continues to increase during production. The resulting silver particles would be a non-uniform size and would be composed of small to large size particles as the current began to rise with time. The color of the water would be yellow, red, brown or muddy looking and silver sludge will begin to drop out and fall to the bottom. The particles of silver are getting too large as the current begins to run away and rise dramatically.
Definitions:
Colloidal silver. When silver particles are suspended and evenly dispersed throughout a solution. All the particles are microscopic and are electrically charged with a positive potential. Since "likes" repel, the particles try to maintain the same distance from each other, this results in a homogenous dispersed solution.
Constant current. Current flow is kept at a constant value by increasing or decreasing voltage as required to maintain the desired (or preset value) current flow. In the process of making colloidal silver, the voltage is reduced as the current tries to rise. This is what keeps the silver particle size.
Runaway. When current flow rises linearly, exponentially or logarithmically. The net effect is the current rises uncontrollably with time.
PPM. Parts per million of a solution. I.e.: 10 PPM silver means 10 parts silver to 1 million parts water. This is generally defined as mg/l. Therefore 1 mg. silver in 1 liter of water is 1 PPM, etc.
PWT Meter. At Walks With Hawks we always test our water for usability prior to making colloidal silver, It will read microsiemens (uS/cm) which is a measure of conductivity. If our water measures less than 2 uS it is acceptable for CS production. I have bought water at different places and I find that Krogers Distilled water is the best. It usually tests about 1.1 to 1.2 (uS/cm) As an additional benefit, is our instrument can closely relate the reading to parts per million (PPM) of ionic/colloidal silver after you have produced it.
If the water was pure to start with, this meter will read colloidal silver directly in ppm by applying a correction factor. I have tested our colloidal silver for ppm using the atomic absorption method and this meter reads those samples within a close percent of the laboratory results.
The manufacture supply's the proper correction factor so we will be able to easily calculate our PPM (parts per million) of colloidal silver.
Note: (The PWT meter is the only meter that works at the accuracy and range desired to measure CS.
