Are chlorine dioxide and chlorine the same thing?Although the name chlorine dioxide (ClO 2 ) includes chlorine, the chemistry of theChlorine dioxide totally different from that of chlorine. A single atom is enough to change everything. The difference between chlorine and ClO 2 comes from their dissimilar chemical structure - and it is also what is responsible for their chemical behavior. It's similar to hydrogen. It is usually a highly explosive gas, but when it combines with oxygen it turns into dihydrogen oxide - commonly known as water . How is chlorine dioxide used in water treatment and how does it work?Currently, ClO 2 is mainly used in North America as the primary disinfectant for surface water with odor and taste problems. It is a powerful biocide, even in very low concentrations (0.1 ppm) and over a wide pH range. ClO 2 penetrates through the bacterial cell wall and reacts with vital amino acids in the cytoplasm of the cell to kill the organism. The by-product of this reaction is chlorite. Significantly, toxicological studies have shown that the disinfection by-product of ClO 2 (chlorite) does not pose . any significant hazard to human healthIs chlorine dioxide only used in urban water treatment?Chlorine dioxide is widely used as a bleaching agent in the pulp and paper industry. In fact, ClO 2 has become the most widely used chemical in bleaching processes to avoid their harmful environmental impact. Chlorine dioxide is also used as a biocide in the food industry for cleaning fruit and vegetables, disinfecting meat and poultry, cleaning process water, disinfecting floating water and for odor control. In industrial processes, ClO 2 is used for industrial water treatment (cooling systems / cooling systems), in ammonia plants, pulp mills (sludge control, paper machines), on oil fields, in air washers, at the Textile bleaching and used in the electronics industry. Chlorine dioxide is also used in medical waste. How does chlorine dioxide affect the environment?Chlorine dioxide is environmentally friendly and a pollution protection technology because it protects the environment and human health from bacteria and from by-products caused by others Desinfektionsmethoden would have been formed. For example, the use of ClO 2 in the pulp and paper industry has eliminated all of the dioxin in the factory waste and thus contributed to a significant improvement in the water ecosystem . Why should I use chlorine dioxide instead of chlorine for water treatment?It should be noted that both chlorine and chlorine dioxide are powerful and effective disinfectants. Chlorine was and is a very effective disinfectant that is responsible for making and storing safe drinking water for people around the world. In cases where surface water as A source of drinking water that contains organic materials, ClO 2 offers the following services. First, ClO 2 uses an oxidizing and not a chlorine reaction. This practically excludes the formation of organic chlorine compounds which are suspected of being carcinogenic. Second, ClO 2 is generated on site, which avoids storage and / or transportation of chlorine . Is chlorine dioxide toxic?Fifty years of work experience has shown that ClO 2 is a safe tool when used correctly. Nearly 4.5 million pounds of chlorine dioxide are used in the manufacture of pulp and paper worldwide every day. However, as with all disinfecting chemicals, if used improperly, If handled, ingested, absorbed, or exposed to too long, they can be toxic. However, it is precisely this toxicity that makes ClO 2 a good water disinfectant . Can I purchase chlorine dioxide directly from chemical dealers?Pure chlorine dioxide cannot be purchased in solid, liquid, or gaseous form. The transport of ClO 2 is not allowed because ClO 2 is a very reactive and effective chemical. Chlorine dioxide must are produced and used at the moment of application. Chlorine dioxide generators are automated and user-friendly . How is chlorine dioxide produced?Chlorine dioxide can either be produced chemically from sodium chlorite or sodium chlorate, or it can be produced electrochemically. Is chlorine dioxide expensive?The cost of chlorine dioxide depends on the cost of the base chemical - sodium chlorite or sodium chlorate - and the chemicals needed to convert these chemicals to ClO 2 . The costs of ClO 2 also depend on the production method used. Compared to the cost of chlorine, those of chlorine dioxide are higher. Nevertheless, chlorine dioxide is an excellent alternative in cases in which chlorine cannot be used due to process engineering or environmental effects. The costs of producing ClO 2 are in fact significantly lower than those of other alternatives such as ozone, which can also be used . for water treatmentCan chlorine dioxide be stored safely?Solutions of about 1% ClO 2 (10 g / l) can be safely stored at 5 ° C for a few months with little change in concentration provided the solution has no free gas space and is protected from light . |
