An In-Depth Discussion

The PANTHER WATER STABILIZER is a special alloy that acts as a catalyst and effects colloidal dispersions in water. It is used to treat water for service in homes, buildings, air conditioning and refrigeration units, boilers, and heat exchangers, to name a few. Since this treatment is catalytic in action, it is economical for continuous treatment. Nothing is added to the water and, other than a degassing effect, nothing is removed from the water. The most important commercial application of the PANTHER WATER STABILIZER is that problems due to scale formation in various water systems are either eliminated or dramatically decreased.

A catalyst, by definition, is an agent that allows an action, either chemical or physical, change to occur at a high and practical rate and without the agent being consumed in the process. Such catalyzed reactions thus can be achieved advantageously at reasonable conditions (temperature, etc.) whereas these reactions might not occur to even a detectable extent under non-catalyzed but otherwise extreme conditions.

A colloid is an aggregate of ions or molecules that is small enough to pass through a filter paper and is easily kept as a suspension of usually undetectable particles. Colloidal suspensions may be stable for quite some time and, unless they are modified, typically do not form larger aggregates or precipitates.

In order to understand how a catalyst effects such a stabilized colloidal suspension in water, one must understand what ingredients are present in normal water and how those ingredients might be changed.

Water normally picks up certain salts and gases as it percolates through the earth, the exact content of which varies with exposure to local and regional soils, rocks, etc. Rain is close to the makeup of distilled water but has small amount of impurities, like fine airborne dirt, etc., which are acquired on passage through the atmosphere and particularly when it contacts some collection system. Even distilled water or deionized water have traces of impurities that arise from their process, piping, and containers. For research purposes water can be purified through approximately a five-step process but may also cost up to $50.00 per gallon. However, water for consumption has to have some minerals as these are vital to life processes. Water treatment for public use may involve chlorination for bacterial control, flocculation and filtration of objectionable sediments.

  1. Total Solids (TS) is a measure of the entire gamut of things in water ranging from suspended dirt to dissolved salts. To determine TS, the liquid is simply evaporated and the residue weighed.

  2. Turbidity (TURB) is the cloudiness or muddy character of a solution. Turbidity indicates the true dispersed or suspended solids, including non-filterable colloids, but gives no value for the truly dissolved salts. Turbidity tests are made and compared to standard cloudy solutions, usually stabilized colloids that have an opaque character.

  3. Conductivity (COND) is an electrical measurement of a solution. The greater the dissolved salt content, the greater the conductivity. In clear water, COND is proportional to TS. High conductivity water has a salt or saline hazard to soil and crops.

  4. Total Hardness (TH) is the amount of certain cations, Ca++ plus Mg++ and others such as iron. Hard water has a high scale forming tendency, requires more soap to just counteract these hard cations (by forming soap curds), and does not taste good. High iron contend not only causes unsightly staining of surfaces but also acts as a promoter for the formation of other scales.

  5. Alkalinity (ALK) & pH are terms that give information as to the amount of reactible base or acid. In normal water, these terms relate to the amounts of carbonate and bicarbonate ions.

  6. Bacteria (BACT) typically measured in drinking water as a check on its suitability. However industrial concern is usually for an iron bacterium which feeds upon sulfate ions in water and converts them to sulfide ions. The sulfide ions attack metallic iron directly where the bacteria are attached, which physically damages the surface and results in more iron ions in the water.

Conventional water softeners remove most of the calcium and magnesium from water and replace them with sodium which does not have hardness properties. This type of softener requires periodic recharging with sodium salts as they are consumed in the process. While chemically softened water is excellent for washing purposes it is not good for drinking or irrigation. Softened water requires very little soap to make the initial suds, as in the "green-soap hardness test."

The PANTHER WATER STABILIZER is not a water softener as discussed above. It removes absolutely no minerals from the water, so hard water will still have exactly the same hardness elements as before treatment with the PANTHER WATER STABILIZER. Therefore, PWS treated water requires exactly the same amount of soap to form the initial suds as does raw water. However, PWS treated water is physically different. Its suspending qualities are modified by catalytic action so that a weak suds solution performs like a strong suds solution. The increased efficiency of dirt removal lowers the total soap consumption to the point where chemical softening is often found unnecessary. Furthermore, PWS treated water provides superb rinses, and often prevents curds, scales, and scums from sticking to any other object.

For those people from Missouri who must "see it to believe it", a simple demonstration of dispersed clay may be performed.

Partially fill two containers with water, one with raw water and one with PWS treated water. Add a handful of clay dirt to each, stir briefly, and let stand for about 20 minutes. Pour off the excess water and then literally feel the difference between the two muds with you have. Note the dispersed or disintegrated condition of the mud in the PWS treated water and the smooth slippery feeling. The clay platelets are easily dispersed into colloidal sizes.

Pitting is by far the most common variety of corrosion in hot water pipes, boiler tubes, condenser tubes, and other heated surfaces. The major cause of pitting is entrained corrosive gases. For example: water containing millions of molecules of dissolved oxygen gas will deposit these as globules at several favored spots on a metal surface when heated. The oxygen naturally oxidizes the metal at these pinhole leaks. Carbon dioxide similarly forms at certain points due to the breakdown of the naturally occurring bicarbonates which are also present in much higher amounts than oxygen. Globules of carbon dioxide react locally with water forming carbonic acid which can quickly eat through an unprotected metal.

For some period of time after a PANTHER WATER STABILIZER is installed, especially in older systems, its action of loosening scale, sediment, and dirt may be limited. During this time that water will be overloaded with particles loosened from mostly the parts closest to the PANTHER WATER STABILIZER. This over suspended concentration of particles may interfere with mechanical action at functional points in the system. Traps and screens may need to be checked and cleaned very often until the system is cleaned. After the system is cleaned, the PANTHER WATER STABILIZER will accomplish the desired results for the entire system. Be advised that, if the condition of the piping system is badly corroded and held together by hard scale, when the PANTHER WATER STABILIZER removes scale leaks may develop, and thus repairs may be anticipated.

The PANTHER WATER STABILIZER does the following:

  1. Inhibits scale by retarding mechanical adhesion and subsequent collection of lime particles.
  2. Softens and removes old scale.
  3. Softens old growths of algae and prevents new attachments.
  4. Removes entrained gases.
  5. Prevents corrosion.
  6. Changes taste, color, and other subtle solution factors.
  7. Since it is catalytic in action, potentially large savings are possible as most consumed chemical costs are avoided.
  8. When suspended materials are not dispersed into a colloidal state then they will be agglomerated into larger particle sizes which will settle out of solution if left static. They may then be removed by normal mechanical means.

The PANTHER WATER STABILIZER uses an exclusive metal alloy that acts as a catalyst, which effects colloidal dispersion thereby enhancing the physical properties of the water. Nothing is added to or extracted from the water other than a degassing effect to improve its quality. This is extremely helpful since entrained gasses are the chief cause of pitting on metal surfaces. Because the effect is catalytic in action, scaling, corrosion and pitting are prevented without the use of chemicals, electricity or magnets.

The PANTHER WATER STABILIZER is practically maintenance free. There are no filters to clean or replace.

The PANTHER WATER STABILIZER is completely self-contained and installs directly in your existing line. Many different models are available to satisfy your specific line size and gallon per minute requirements. Due to our unique in-line design, convenient installation may be performed virtually anywhere. The PANTHER WATER STABILIZER unit should be at least 1-1/2 times the diameter of the line it is to be installed in.
