Tutorial chlorine dioxide generator

Chlorine dioxide is used worldwide as a disinfectant and more important. This success is built: by the toxic effects on organisms, the high degree of independence from the pH of the water and the difference of the reaction by-products of chlorine dioxide to the reaction by-products of chlorine. A detailed justification for the use of chlorine dioxide should be read in newspaper articles to Filterverkeimung and in the tutorial to Legionella. The theme of the following lines is the on-site production (in situ) shown of chlorine dioxide in a generator.

Functionality of a membrane-covered amperometric sensor

2- and 3-Elektode systems. A nozzle of the flow-through chamber with 6mm diameter approximately 15 millimeters distance brings a constant jet of fluid (symbolized by a blue arrow) with the disinfectant in a direction plumb to the membrane (1). The membrane allows molecules of the disinfectant mainly pass through . These molecules put a pathway in the electrolyte liquid (2) to the working electrode (3) back. The working electrode (3) is of precious metals (gold or platinum) so they do not corrode. The working electrode (3) is with a very small but accurate electrical voltage.

The advantages of membrane-covered amperometric sensors

If we talk about disinfection, then most people immediately think of "chlorine". Here is often overlooked, that chlorine in different forms occurs. While the right eye can be protected by "free chlorine" for infections, is the left eye may be the result of bounded chlorine and his children in the air. This bound chlorine is the reason for the bad taste and smell in the air - but has very little to do with the disinfection or our protection. Membrane-covered sensors can also detect this kind of chlorines.

The selection of membrane-covered amperometric sensors

Tutorial to choose Membrane covered amperometric sensors with detailed explanations of the parameters. In this table, you can select the correct sensor. In the footer of the table filter can be written, which restricts the number of rows. Please also note the informations, which will be displayed in the right columns by horizontal scrolling. Find out in the fields measuring size, Subgroup, Measuring range, Measuring water, Pressure, pH range, Temperature, Cross sensitivity, Reaction time, Connections, Downloads, about the existing possibilities and conditions.

Function of the cleaning device at the amperometric sensor

In the membrane-covered amperometric sensor, the working electrode is separated from the water and disinfectant by a most sensitive membrane. A cleaning device is not realizable. This membrane may be by substances, which are located in water, be contaminated. This contamination holds the molecules to be measured back and reduces the sensitivity of the measurement. Caused by the membrane, a membrane-covered amperometric sensor is sensitive to pressure. For some disinfectant there is the possibility, carry out the measurement without membrane. The missing membrane leads to a pressure stability of the sensor. At the same time this case, the working electrode is exposed, so that the surface can be cleaned mechanically.

Disinfection 02 Sterilisation

posted in: Terms 0

Sterilisation: process, be freed by the subjects of microorganisms. with sterilization, refers to sterilization and disinfection process, by the materials and articles of live microorganisms including their dormant stages (for example spores) be freed. The thus achieved state of materials and articles are called "sterile".
