Re: Forum: water sanitizers and disinfectants
Any product in the powder form or tablet form will not give consistent product. I hope they should have two tablets one is base and the other is an activator. Here the problem is if one tablet dissolves fast and other a bit slow the efficacy of the product goes down. Consistency is the main problem and its Stabilized chlorine dioxide not pure chlorine dioxide.
Active vs. Stabilized Chlorine Dioxide Vs Pure Chlorine Dioxide
Active and Stabilized chlorine dioxide are not the same. The term, "Stabilized Chlorine Dioxide", is misleading. There is little or no chlorine dioxide (ClO2) in the stabilized chlorine dioxide compound.
Stabilized chlorine dioxide is not a pure chlorine dioxide. “the term stabilized chlorine dioxide is a misnomer and preparations so labeled are specialty formulations incorporating sodium chlorite and proprietary activators” that are designed to slowly release chlorine dioxide. These products are not intended for use in drinking water applications because high levels of chlorite ion (CLO2-) remaining after activation and the relatively low clo2 concentrations”
From the chlorine dioxide hand book, American water works Association 1998.
Stabilized chlorine dioxide products are prepared by buffering sodium chlorite with carbonate or phosphate and hydrogen peroxide. This stabilizes the chlorite, not chlorine dioxide. Stabilized chlorite is not the same as chlorine dioxide, and does not have the same oxidizing properties. The oxidizing action of chlorite is much lower, and is far less useful. Another main difference between the two compounds is that chlorine dioxide is a gas, and sodium chlorite is a salt.
To make active chlorine dioxide, an acid is mixed with chlorite, which slowly releases the gas. The gas is then captured in a solution or gel. This reaction normally requires high acidity (low pH). Frontier, however, has patented a method of speeding the release of chlorine dioxide at mild acidity (closer to neutral pH). The resulting product is then optimized for use on the body.
The manufacturers of stabilized chlorine dioxide appropriate the term "stabilized" to capitalize on the beneficial properties of chlorine dioxide. The misleading stabilized chlorine dioxide phrase has become popular by effective marketing. Many people refer to it without knowing the difference, and research papers incorporate it incorrectly. The stabilized manufacturers "justify" the misnomer by stating that the term has been in use for some time.
Vinci Dioxide is a brand new concept in which a pure chlorine dioxide 0.35% is generated in water by the reaction of two stable liquids. The chlorine dioxide produced is parctically 100% pure (99.9%). There are no by products such as free chlorine and chlorite. Any risk of explosion diappears by the use of inhibitor components used. The kinetic half time at 20 deg C is between 30 and 45 days, stored in a dark and dry place. Due to all this advantages and the superior disinfection capacity, chlorine dioxide is now a very useful disinfection product for many (small and big) industrial activities.
