A recent study in the Journal Ozone Science and Enginnering has shown that electrolysis followed by volatilization can remove Br from drinking water and as a result lower the formation of bromate from ozone water treatment. This is an important issue since a large number of water sources contain Br ion. Ozone can react under […]

Dangers of Bromate in Drinking Water May Be Overstated
Ozone can react with bromide ion to form bromate. Currently, the USEPA has a limit of 10 micro grams per liter for ozone in drinking water. This level has been extended to other water treatment applications, for example, ground water remediation. The USEPA is considering lowering the allowable limit for bromate to 5 micro grams […]
New Standards to Impact the Use of Hypochlorite for Drinking Water
Changes to NSF/ANSI Standard 60 may impact the use of sodium hypochlorite in drinking water systems. New rules are being considered for the contaminates bromate, perchlorate and chlorate, all of which can be traced to sodium hypochlorite. US drinking water systems are concerned about disinfection products that might contaminate the water either from contaminants that […]
Bromate in Drinking Water may not be as Serious as Previously Thought
Currently, allowable levels of bromate in drinking water are 10 micrograms per liter. The US EPA and WHO are considering lowering this limit. Under certain conditions, bromate may be formed when drinking water with bromide ion content is ozonated. Technologies exist to prevent or mitigate this formation, but question have been raised as to whether […]
