Many people assume that we have an endless supply of clean, fresh water. However, with the growing population and increased water consumption for daily use, agriculture, and industry, we can no longer take water for granted. It is crucial for countries to address this issue soon to avoid severe water shortages.
Disinfectants in drinking water have played a key role in eliminating waterborne diseases. In North America, most water treatment plants use chlorine to disinfect water and maintain a residual level in the distribution system to prevent bacterial regrowth. While chlorine has undoubtedly saved lives, recent studies indicate it also has drawbacks. Many people dislike the taste of chlorine, leading them to opt for bottled water instead of tap water, which negatively impacts the environment. Therefore, it is important to explore alternative disinfection methods that can effectively eliminate waterborne diseases without harming the environment or human health.
Chlorine dioxide (ClO2) is a chlorinated disinfectant that serves as an effective alternative to chlorine for primary disinfection at treatment plants. Disinfection is crucial for ensuring safe drinking water; the health risks from disinfectants and their by-products are significantly lower than the risks posed by untreated water. Typically, chlorine dioxide is dosed at levels ten times lower than chlorine, which helps maintain water taste without any negative impact.
The Chlor-D Tablet is a specially formulated effervescent tablet designed to generate liquid chlorine dioxide when dissolved in water. This unique mixture of ingredients reacts quickly and safely to create a long-lasting chlorine dioxide solution, which can be used in various applications. Simply add the tablet to a specific volume of water, and the resulting concentrate can be dosed into the main water distribution system for effective disinfection.
The stock solution, once prepared, has a shelf life of approximately 30 days when stored in a dry, dark, and cool place. Once dosed into water lines, Chlor-D maintains its effectiveness with a good residual, depending on the quality of the incoming raw water and the level of contamination in the system. Easy to use, store, and transport, Chlor-D is safe for humans, livestock, crops, equipment, and the environment when used at appropriate dosing rates. While chlorine dioxide can produce by-products such as chlorite and chlorate, these must be monitored to ensure safety and efficacy.
Chlorine dioxide (ClO₂) is widely used globally as a drinking water disinfectant and is highly effective in various applications, including household water, emergency water treatment, food production, municipal water, wastewater, industrial water treatment, and agricultural water for animals and crops. As both a disinfectant and an oxidant, ClO₂ is a broad-spectrum micro-biocide effective across a wide pH range (4-10), known for its ability to disinfect bacteria and viruses.
Opting for chlorine dioxide over chlorine can help reduce the formation of harmful disinfection by-products such as trihalomethanes and halogenated acetic acids. The unique chemistry of ClO₂ does not chlorinate; instead, it remains a small, highly energetic molecule and a free radical even in diluted aqueous solutions. At high concentrations, it reacts swiftly with reducing agents but remains stable as a diluted solution when stored in a sealed container in a dark, cool room. ClO₂ has a higher capacity to deactivate pathogens at lower dosing rates compared to most other disinfectants.
