摘要

composition for a microbicidal effect in a water system, treated water system containing a composition, method for stabilizing the chlorine for use as a biocide in the treatment of water in a processing system, paper and method for increasing the optical brightness in the paper produced in a paper processing system is a composition for a microbicidal effect in a water system such as a pulp and paper processing line with an aqueous slurry. the composition comprises a free chlorine generating biocide comprising a source of chlorine, urea and an alkali in a concentration sufficient to obtain a pH greater than 10, and typically a pH of at least 11.
