Bromine is found in seawater and exists as the bromide ion at a level of about 65 mg/l. Bromine has been used in swimming pools and cooling towers for disinfection, however use in drinking water is not recommended. Ethylene bromide is used as an anti-knock additive in gasoline and methyl bromide is a soil fumigant. Bromine is extremely reactive and corrosive, and will produce irritation and burning to exposed tissues. Over 0.05 mg/l in fresh water may indicate the presence of industrial wastes, possibly from the use of pesticides or biocides containing bromine. Bromide is extensively used in the pharmaceutical industry, and occurs normally in blood in the range of 1.5 to 50 mg/l.
Fresh and potable drinking water is an essential element of life needed to attain a healthy and lovely livelihood. Humans rely on the consumption of water every day in great quantity in order for our bodies to continue functioning and developing. However, it is vital for the water we ingest to be clean and free of unwanted substances such as bromate that can lead to health complications. Fortunately, Netsol provides various water treatment systems that can assist you in removing harmful contaminants found in water.
Bromate arises when ozonation is utilized to treat contaminated water that consists of bromine naturally existing in the source water. Such characteristics found in contaminated water including, pH of the feed water, bromide ion concentration, degree of ozone and reaction time, influence the formation of bromate. The symptoms of bromate poisoning can comprise of vomiting, diarrhoea, nausea, nerve and kidney issues. It must be noted that these symptoms usually involve the consumption of water that has over a thousand times more bromate than normal drinking water. Additionally, exposure to very high levels of bromate can lead to the acquisition of hearing loss and nervous system effects.
HOW TO REMOVE BROMATE FROM DRINKING WATER?
There is great difficulty in removing bromate from drinking water, which makes it more suitable to prevent its presence in the feed water altogether. This can be accomplished by utilizing chlorine gas, clean hypochlorite with low bromate content and foregoing the usage of ozonation which contains bromide. While it is possible to remove bromide content from the water, prior to utilizing ozonation, this can be very expensive.
Useful water treatment solutions include activated carbon filtration, anion exchange, and reverse osmosis systems. Using ammonia and the right activated carbon filtration are commonly recommended water treatment solutions, however each of these methods have their own drawbacks.
Reverse osmosis systems are considered the most effective technology available for the removal of bromate and other disinfection by-products. Reverse osmosis systems with activated carbon filtration are capable of eradicating more than 96% of bromate-related pollutants in water.
Keep in mind that bromates in small amounts prove to be harmless and if only ingested in large amounts proves harmful to the human body. As a carcinogenic by-product of a water treatment method, it ought to be removed from the drinking water. Bromate can aggravate kidney problems which are suffered prior to the intake of high levels of bromate. It can also cause gastrointestinal complications.
