    • The invention relates to treatment of aqueous streams and aqueous systems with ozone. The aqueous stream comprises a closed loop system providing transport from a production locus to a processing locus for a variety of products. The aqueous stream can contain a challenge soil load and a microbial load. A treatment zone is defined through which the aqueous stream passes. The treatment zone is contacted with a sufficient concentration of ozone to substantially reduce the microbial population and to substantially reduce the number of microorganisms that can generate slime on the interior of the system. An amount of ozone is added to the aqueous stream in the treatment zone such that once the microbial populations are reduced to a safe level, the ozone concentration is also reduced to a level substantially safe for contact with operating personnel and product. Typically, such concentration is less than one part by weight of ozone per million parts by weight of aqueous system, preferably less than 0.5 parts by weight of ozone per million parts of aqueous system. The use of a treatment zone in an aqueous system segregates the ozone from release into areas frequented by operating personnel, sensitive materials or product.
    • 本发明涉及用臭氧处理含水物流和含水体系。 含水流包括提供从生产地点到各种产品的加工场所的运输的闭环系统。 水流可能含有挑战性土壤负荷和微生物负荷。 定义一个处理区,水流通过该处理区。 处理区与足够浓度的臭氧接触以显着减少微生物群体并且显着减少可在系统内部产生粘液的微生物数量。 将一定量的臭氧添加到处理区中的含水流中,使得一旦微生物种群减少到安全水平,臭氧浓度也降低到与操作人员和产品接触的基本安全的水平。 通常,这种浓度小于每百万重量份水性体系的臭氧重量的1重量份,优选每百万份水性体系小于0.5重量份的臭氧。 在水系统中使用处理区将臭氧从释放中分离出来,由操作人员,敏感材料或产品经常出现的区域。

    • We have found a new and useful process to generate peroxy acid sanitizing and bleaching compositions at the point-of-use, the process comprising introducing hydrogen peroxide and a carboxylic acid into a reactor at about 0.1 to 10 moles of hydrogen peroxide per mole of acid, and contacting the hydrogen peroxide and carboxylic acid in the presence of a sulfonic acid resin and in the substantial abssence of active metal ions which forms an aqueous peroxy acid composition at a concentration from about up to 20 wt %. Using this process, warewashing, laundry sanitizing and bleach, and hard surface sanitizing compositions can be produced.
    • 已经发现了一种在使用时生产过氧化物消毒剂和漂白组合物的新颖且有用的方法。 在该方法中,过氧化氢和羧酸以每摩尔羧酸0.1-10摩尔过氧化氢的平均量引入反应器中,然后相互接触。 过氧化氢和羧酸与磺酸树脂并且基本上不含任何活性金属离子,由此形成浓度高达约20%的过氧酸水溶液组合物, 重量。 使用该方法,可以生产工业洗涤组合物,用于衣物的消毒和漂白组合物以及用于消毒硬表面的组合物。
