摘要：
"improved biocontrol through the use of chlorine stabilizer mixtures" a composition and methods of its use, the composition comprising: a source of halogen, urea and an additional halogen stabilizer excluding urea, optionally an alkali in a concentration sufficient to provide said composition having a ph greater than 10； and optionally excluding a stabilized bromine compound from said composition, is disclosed. Additionally, a method for reducing biological activity in a process flow is disclosed. The method comprises: providing a composition to a process flow, wherein said composition contains: a halogen, urea and an additional halogen stabilizer excluding urea, optionally an alkali at a concentration sufficient to provide said composition with a ph greater than 10； and optionally excluding a stabilized bromine compound from said composition. The invention is also directed to compositions and methods of their use as biocidal agents effective for water flows. The composition comprises a halogen source, halogen stabilizers containing a sulfur-bearing species and ammonium / urea salts, and an alkali. The sulfur-containing species includes sulfamic acid or its salt equivalent. The ratio of nitrogen mixture of sulfur-containing species to ammonium or urea salts can be optimized at any rate. Because of the optimized mixing ratio of halogen to stabilizer and that of ammonium salts to sulfamic acid or sulfamate, a synergistic effect occurs that both increases the effectiveness of the composition as a biocide and avoids adverse impacts on other chemicals that are present in the flux. water (such as pulp paper additives and papermaking water streams). The composition is easy to form and easy to introduce into a water stream of interest. Their introduction can be as simple as mixing two reagent containers prior to introduction into the water process stream.resumo “biocontrole aperfeiçoado através do uso de misturas de estabilizador de cloro” uma composição e métodos de seu us
