    • This invention provides zinc-free aqueous brine compositions. These zinc-free aqueous brine compositions have a density of about 14.3 pounds per gallon or more, and a true crystallization temperature of about 20°F or less, and comprise water and one or more inorganic bromide salts, with the provisos that when calcium bromide is present, one or more other water-soluble inorganic salts are also present, when lithium bromide is present, calcium bromide is absent, when bismuth(III) bromide is present, one or more other water-soluble inorganic salts are also present, and for a true crystallization temperature of about 10°F or less, when manganese(II) bromide is present, one or more other water-soluble inorganic salts are also present. Processes for forming these zinc-free aqueous brine compositions are also provided.

    • Described are highly concentrated liquid biocidal solutions formed in water from (a) specified bromine sources (e.g., BrCl or mixtures of BrCl and Br2) and (b) alkali metal salt of sulfamic acid and/or sulfamic acid and alkali metal base, wherein the solution contains >160,000 ppm of active bromine. Solutions of this type have been found to have greater stability than a commercially-available solution made from the same components containing 148,600 ppm of active bromine. Also described are new, water-soluble, solid state biocidal products formed by removing the water from solutions made in water from (a) and (b) irrespective of the initial concentration of active bromine. Removal of water can be accomplished by flashing or distillation at reduced pressure or preferably by spray drying. Such solid state products are typically in the form of powders or small particles, but can be compacted into larger forms preferably with the aid of one or more suitable binding agents. a combination of any two or all three of (a), (b), and (c).

    • Microbiological control in water systems is achieved with an amount of 1,3-dibromo-5,5-dimethylhydantoin that is less than the amount of N,N'-bromochloro-5,5-dimethylhydantoin required to achieve the same degree of microbiological control. The methods of combating Escherichia coli and/or Enterococcus faecium in an aqueous medium, and biofilms such as formed by Pseudomonas aeruginosa on surfaces contacted by the aqueous medium, involve introducing into the medium a biocidally effective amount of 1,3-dibromo-5,5-dimethylhydantoin. A microbiological control agent for use in water in accordance with U.S. Environmental Protection Agency regulations is purveyed in containers of a water control agent comprising 1,3-dibromo-5,5-dimethylhydantoin, which containers bear a label having thereon dosage levels pursuant to requirements promulgated by the U.S. Environmental Protection Agency. The 1,3-dibromo-5,5-dimethylhydantoin is used or purveyed either as a product having a large average particle size (e.g., 175 microns or more) or in the form of a compacted product. The compacted product can be formed without using a binder where the average particle size of the 1,3-dibromo-5,5-dimethylhydantoin is about 175 microns or more. Alternatively, the compacted product can be formed using a micronized synthetic polyolefin-based hydrocarbon wax and/or a micronized synthetic polyfluorocarbon wax as a binder, provided the wax is compatible with the 1,3-dibromo-5,5-dimethylhydantoin. In this case, the average particle size can be in the range of 20-600 microns. Similarly, the compacted product can be a product formed from 1,3-dibromo-5,5-dimethylhydantoin having an average particle size of at least 175 microns, using an amount of a saturated, normally solid, fatty amide as the binder.
    • 水体系中的微生物控制是通过一定量的1,3-二溴-5,5-二甲基乙内酰脲来实现的,该量少于实现相同程度微生物控制所需的N,N'-溴氯-5,5-二甲基乙内酰脲的量 。 在水性介质中对抗大肠杆菌和/或屎肠球菌的方法,以及生物膜,例如由铜绿假单胞菌形成的表面,其与由 包括向培养基中引入生物有效量的1,3-二溴-5,5-二甲基乙内酰脲。 根据美国环境保护局规定在水中使用的微生物控制剂在含有1,3-二溴-5,5-二甲基乙内酰脲的水控制剂的容器中提供,该容器具有根据要求具有其剂量水平的标签 由美国环保署颁布。 1,3-二溴-5,5-二甲基乙内酰脲作为具有大平均粒度(例如175微米或更大)的产品或以压制产品的形式使用或提供。 可以不使用1,3-二溴-5,5-二甲基乙内酰脲的平均粒径为约175微米或更大的粘合剂来形成压制产品。 或者,如果蜡与1,3-二溴-5,5-二甲基乙内酰脲相容,则可使用微粉化的合成聚烯烃基烃蜡和/或微粉化合成多氟碳蜡作为粘合剂来形成压制产品。 在这种情况下,平均粒径可以在20-600微米的范围内。 类似地,压实产品可以是使用一定量的饱和的,通常为固体的脂肪酰胺作为粘合剂,由平均粒度至少为175微米的1,3-二溴-5,5-二甲基乙内酰脲形成的产品。
