Chlorine chemistry helps keep families healthy and improves our environment:. Chemical Concentration Contact Time Advantage Disadvantage Chlorine 50 ppm in water between 75 and 100 F 7 sec. For instance, Phenolics types of disinfectants are very good for killing bacteria. ... State the advantages and disadvantages of chlorine as a disinfectant ; This is a disadvantage. Effect on a wide variety of bacteria; highly effective; not … Each alternate disinfectant has its advantages and disadvantages. With gas chlorine, the addition of an alkali is needed to keep the pH up to the desired pH 7.4. 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. 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. 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). During chlorine dioxide production processes, large amounts of chlorine are formed. chlorine is rapidly inactivated by organic matter. Chlorine is an ideal sanitizer and prevents much waterborne illness and disease every day. For comparison, chlorine is also shown. Uses & Benefits. Free chlorine reacts with organic matter to form halogenated disinfection byproducts. Used for pools and town water treatment. Positives: No handling required. 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. Chlorine dioxide and its disinfection byproducts chlorite and chlorate can create problems for dialysis patients. Advantages * Chlorine is a powerful oxidizing agent thereby getting rid of a lot of bacteria in water. Corrosiveness to surfaces is a major disadvantage when using chlorine, and high temperature increases the risk of corrosion. Chlorine dioxide (ClO2) Ozone (O3) Ultraviolet Radiation (UV) What are some of their 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. Chlorine chemistry helps keep drinking water and swimming pools safe. It can form chlorine gas, which burns the eyes, nose and mouth. Chemical treatment (Chlorine): Chlorination is by far the most popular method of chemically treating wastewater, due to its number on advantage … Chlorine has some advantages and disadvantages, as do all types of sanitizers. Does chlorine dioxide form byproducts? * Chlorine is commercially available * Chlorine is very economical Disadvantages * Chlorine does not exterminate all bacteria. Disinfectants can kill germs and microorganisms which may not be seen with the naked eye. The following table shows these advantages and disadvantages. Chlorine is less affected by water hardness when compared to other sanitizers. Water. One of the most important advantages offered by disinfectants is for the control of diseases. Advantages. You have prepared a bucket full of water and bleach to clean the pool that has been dirtied with soil, leaves, and so on. Advantages and Disadvantages of Different Chemical Sanitizers 17.
