over simplified explanation is as follows. The copper ion destroys the algae and bacteria by piercing the outer membrane and disrupting enzyme balance. This also allows for other halogens present to enter the cell and help destroy it. Silver ions are effective as a sanitizer because of its efficiency in interrupting DNA production preventing reproduction and accelerating the death phase of the bacteria and viruses.

NO. The Sigma III Pool Purifier, unlike many competitor's systems, allows you to control the amount of copper and silver in the water. A copper test kit is provided with every Sigma III unit so you, the customer, can determine the amount of copper in your pool. The levels of copper and silver that will need to be kept in your pool water are .4ppm copper and .02ppb silver, these amounts are smaller than that allowed by U.S. drinking water standards.

Silver ions in a solution cannot exist without water, so when the water is evaporated the silver ions (cations) must combine with an available anion to form a compound. The predominant anions present in a silver colloid solution are hydroxide and carbonate. The compounds thus formed are silver hydroxide and silver carbonate. Silver hydroxide is unstable and reduces to silver oxide and hydrogen. The silver carbonate will reduce to silver oxide and carbon dioxide. See similar questions...

Any fuel gas lines installed using copper tube must be brazed using a filler metal containing less than 0.05% P (phosphorus) and a melting temperature greater than 1000 degrees F. The only filler metal (trade and industry standard) that contains less than the 0.05% P would be an AWS BAg type alloy (according to the American Welding Society’s AWS A5.8 specification). In no case should solder or “soft-solder” be used to join copper tube and fittings in fuel gas systems. See similar questions...

The short answer is no. While the mining reform effort has focused on gold because of its high visibility and economic value, silver, copper, platinum, palladium, zinc and lead are also part of the story. Silver, copper and lead can be by products of gold mining; gold and silver can be by-products of copper mining; and copper and gold can be by-products of silver mining. As much as 75% of silver production comes from mining gold, copper, lead, and zinc. See similar questions...

A set of electrodes, made up of an anode and cathode are placed in a flow cell. This flow cell is placed in-line with the circulation system. A controller provides a low voltage, alternating DC current. This is passed between the anode and cathode. The voltage causes some of the outermost atoms of the anode to lose an electron, thus becoming positive ions, which attempt to flow across to the cathode. In this process, the ions are carried away by the flow of water. See similar questions...

In an unsaturatedsolution, ions are dispersed throughout the solvent by repulsive force and exist as separate entities. However, in a saturated solution, ions will precipitate out as large flakes of metallic silver particles as the solution cools. These flakes are usually flat and can grow to a very large size, up to 0.100 inches in diameter, and drop to the bottom. In a saturated solution, silver ions will recover an electron from an anion as they precipitate to metallic silver. See similar questions...

element that has either received an extra proton, or has loss an extra proton, and is out of balance. This water is very active or chaotic. See similar questions...

Yes. The EMEW? cell can selectively electrowin a specific metal in the presence of others, the order in which metals are removed from solution is determined by their position on the metal activities series. See similar questions...

You should wash or sanitize your hands often. Probably more often than you do now because you can't see germs with the naked eye or smell them, so you do not really know where they are hiding. See similar questions...

The pool or spa must be cleared of all pool users and the pool closed for use while the disinfection procedures are being followed: Remove all visible fecal material. If a pool water vacuuming device is used, the waste water should be discharged to the sanitary sewer, not back into the pool recirculation system. Raise and maintain a free chlorine residual in the pool water for a sufficient length of time to disinfect the pool water. See similar questions...

Probably not. An experiment commonly performed in high-school chemistry classes will turn a cent to a silver color, and some companies will silver-plated items. For more information, Ken Potter discusses authenticating silver pennies (more accurately, cents). See similar questions...

If the water is over 0.1 ppm (parts per million) (which is 0.1 mg/L), I recommend an alternative source. While 0.1 ppm isn't particularly hazardous, it indicates that significant copper is coming from somewhere, and at certain times or under certain circumstances the level might be quite a bit higher. See similar questions...

There are no concerns in this area. For a complete report, go to our Press Section for a report titled Copper Roofs and Water Runoff. See similar questions...

It is always a good practice to sanitize the house and equipment between batches of chickens. There is a saying, "An ounce of prevention is worth a pound of cure" !!! This is especially true of chickens so are so susceptible to diseases and are constantly eating off the ground!!. Wash all pens, waters and feeder surfaces with a good detergent. Add 1 oz. of disinfectant to each gallon of water and saturate by spraying all surface areas. See similar questions...
