Advantages. Corrosiveness to surfaces is a major disadvantage when using chlorine, and high temperature increases the risk of corrosion. Each alternate disinfectant has its advantages and disadvantages. Chlorine chemistry helps keep drinking water and swimming pools safe. Chlorine dioxide (ClO2) Ozone (O3) Ultraviolet Radiation (UV) What are some of their advantages and disadvantages? Advantages * Chlorine is a powerful oxidizing agent thereby getting rid of a lot of bacteria in water. Chlorine is an ideal sanitizer and prevents much waterborne illness and disease every day. For instance, Phenolics types of disinfectants are very good for killing bacteria. Positives: No handling required. Uses & Benefits. During chlorine dioxide production processes, large amounts of chlorine are formed. For comparison, chlorine is also shown. With gas chlorine, the addition of an alkali is needed to keep the pH up to the desired pH 7.4. * Chlorine is commercially available * Chlorine is very economical Disadvantages * Chlorine does not exterminate all bacteria. Other disadvantages of hypochlorites include corrosiveness to metals in high concentrations (>500 ppm), inactivation by organic matter, discoloring or “bleaching” of fabrics, release of toxic chlorine gas when mixed with ammonia or acid (e.g., household cleaning agents) 523-525, and relative stability 327. Free chlorine reacts with organic matter to form halogenated disinfection byproducts. This is a disadvantage. Effect on a wide variety of bacteria; highly effective; not … Chlorine chemistry helps keep families healthy and improves our environment:. Chlorine has some advantages and disadvantages, as do all types of sanitizers. Advantages and Disadvantages of Different Chemical Sanitizers 17. Chemical treatment (Chlorine): Chlorination is by far the most popular method of chemically treating wastewater, due to its number on advantage … Disinfectants can kill germs and microorganisms which may not be seen with the naked eye. ... State the advantages and disadvantages of chlorine as a disinfectant ; The Real Truth We rely on a wide array of cleaning products including soaps, scents, softeners, bleaching products, polishes, special cleaners for glass, drains, bathrooms and ovens to keep our homes perfectly clean and smelling great. You have prepared a bucket full of water and bleach to clean the pool that has been dirtied with soil, leaves, and so on. Water. Used for pools and town water treatment. The following table shows these advantages and disadvantages. This chlorine produces acids — hypochlorous acid (free chlorine) and hydrochloric acid — when added to pool water, whereas the first two chlorines produce an alkali. One of the most important advantages offered by disinfectants is for the control of diseases. chlorine is rapidly inactivated by organic matter. Cons While chlorine does an excellent job of destroying most toxins in the water supply, it also introduces other types of toxins, such as trihalomethanes (THMs). Major Advantages of Using Chlorine/Chloramines as a Disinfectant The advantage of chlorination is that it continues to kill bacteria as water moves through pipes to the tap. Does chlorine dioxide form byproducts? Chlorine dioxide and its disinfection byproducts chlorite and chlorate can create problems for dialysis patients.
