Abstract
Reduced stabilization time of oxidation-reduction potential is achieved in a recreational body of water by baseloading bromide ions and dialkylhydantoin prior to biocidal treatment of the water body with N,N′-dihalo-5,5-dialkylhydantoin.
Claims4
A recreational body of water in operable contact with an oxidation-reduction potential sensor to which body of water has been added (A) a source of bromide ion and at least one dialkylhydantoin in which the alkyl groups each contain independently in the range of 1 to about 4 carbon atoms and then to which is added (B) at least one N,N′-dihalo-5,5-dialkylhydantoin in which one halogen atom is a bromine atom and the other halogen atom is either a bromine atom or a chlorine atom, and in which one alkyl group is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms, said body of water having a stable oxidation-reduction potential whereby said sensor more accurately tracks active bromine concentration of said body of water.
