| titleOfInvention | Stabilized and activated bromine solutions as a biocide and as an antifouling agent |
| abstract | Abstract The invention provides a process of removing or preventing biofouling in a volume of an aqueous liquid or on a surface in contact with an aqueous liquid, comprising (i) providing an aqueous composition (stock antifouling solution) containing a urea derivative and an active halogen source, wherein the molar ratio urea derivative/halogen is at least 1/1, and the pH of said aqueous composition is acidic; and (ii) contacting said volume or said surface with said composition obtained in step i); wherein said active halogen source is selected from C12, DC-DMH, DC-MEH, TCCA, Na DCC, and a mixture of an oxidizer with a bromide source selected from HBr and a bromide. The invention further provide a process of preparing an antifouling or disinfecting composition comprising water, a urea derivative, and active bromine, comprising (i) preparing an aqueous solution of said urea derivative; (ii) adding to said solution obtained in step i) an active chlorine source selected from the group consisting of C12, TCCA, Na-DCC, DC-DMH, and DC-MEH, at a temperature of between OC and 250C, while stirring, wherein the molar ratio urea/chlorine is greater than about 1/1, thereby obtaining an aqueous composition of stabilized chlorourea derivative; and optionally (iii) admixing to said stabilized chlorourea derivative a bromide or HBr to an amount corresponding to a molar ratio Br/Cl of from 0.5 to 2.0, at a temperature of between OC and 25CC; wherein a time period between said steps ii) and iii) is up to two years. |
