Bromine has a greater efficiency over a wider pH range compared to chlorine. While bromine dissolves better in water temperatures over 75 degrees Fahrenheit chlorine is more effective in temperatures less than 75.
Fluorine Halogens Element Chemistry Chemistry Electron Configuration
Bromine is close in size and weight to Iodine and will compete for binding of Iodine receptors in the thyroid gland.
Bromine vs chlorine health. Bromine is very similar to Chlorine in the way that it kills bacteria and harmful contaminants but Bromine is most used to sanitize hot tubs and spas because it is more stable than Chlorine in warmer temperatures. Above 75F bromine remains stable whereas chlorine is more effective in temperatures as low as 65F. Chlorine alone Chloroform CHCl 3 -- EPA lists this as a carcinogen likely under high exposure conditions Bromine or combination.
While chlorine keeps your water crystal clear by breaking down oils and other organic matter bromine will not. Bromine stays more stable at high temperatures. The other reason why the ideal range for residual bromine is a little higher than for residual chlorine is that owing to their relative atomic weights it takes roughly twice as much bromine as ppm to get the same oxidizing capacity as chlorine.
Some bromine-containing compounds were historically used as sedatives drugs that can make people calm or sleepy. Bromine has a big advantage over chlorine in killing bacteria and viruses whereas chlorine has an advantage in killing algae more rapidly. Youll need a spa cover to safeguard the water.
Kills bacteria in your spa for a longer period of time than chlorine. Chlorine comes in several forms and can easily be stored in tablet form in a floating device that stays in the pool keeping the levels perfect for up to a week. Bromine is more difficult to wash off because of its long lasting stability.
This makes bromine a better choice for hot tubs and spas and an unheated. You may even end up using less bromine. It irritates the eyes and mucous membranes and in contact with the skin produces lesions which heal with difficulty.
Unlike chlorine byproducts or chloramines bromamines do not cause eye irritation or skin irritation or have unpleasant odors according to the South Australian Health Commission and Lentech Water Treatment Solutions. Exposure and Skin Effects. Bromine works better at higher temperatures than chlorine.
Dissipates more quickly than bromine and therefore needs to be replaced more often. Compared to bromine chlorine requires daily maintenance for balance. For bromine the ideal levels range from about 3 PPM to 5 PPM parts per million though 5 PPM is optimal.
Generally speaking the brominated organics are more troublesome than the chlorinated ones. Water transparency might be another consideration. It is worth noting that you will need to use larger doses of bromine compared to chlorine to achieve peak cleanliness.
It is said that the effectiveness of chlorine decreases beyond a pH of 74 while the disinfecting power of bromine remains in force even at pH 78. Bromine is a dark-red dense liquid with a disagreeable odor. 1-3 ppm parts per million Bromine.
3-5 ppm parts per million Though you need more bromine to clean the same amount of water as chlorine you have to add chemicals less often so the dosage will even out over time. Products containing bromine are used in agriculture and sanitation and as fire retardants chemicals that help prevent things from catching fire. There is no UV degradation protection if using this compound.
Chlorine is slightly more reactive than bromine making it somewhat more effective. You shouldnt use bromine if levels are low or if bromine levels are too high. I list some of the ones the EPA notes below for chlorine and bromine or combo compounds.
Bromine is more effective than chlorine when pH levels rise. Chemically speaking chlorine is a stronger halogen with a quicker oxidation reaction. But bromine has a larger atomic size with an extra valence shell.
While chlorine may work more quickly bromine is more stable than chlorine especially in warm water. When bromine combines with the nitrogen from urine it produces byproducts called bromamines. For chlorine on the other hand the ideal levels range from about 1 PPM to 3 PPM though 3 PPM is optimal.
Bromine can also be found as an alternative to chlorine in swimming pools. Chemically less reactive than chlorine it combines with both metals and nonmetals.
