摘要： The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.

摘要： A boiler feed water treatment system (1, 100, 200) that includes two or more water softeners (20, 21), a totalizer (4) for measuring a quantity of water treated by each softener (20, 21) between regeneration cycles, a hardness analyzer (5) for measuring the hardness of water treated by the softeners (20, 21), a chemical doser (7, 107) for introducing a scale inhibitor into the feed water and a controller (9, 209a, 209b) for controlling the operation of the system (1, 100, 200). The controller (9, 209a, 209b) controls the chemical doser (7, 107) to introduce into or increase the concentration of a scale inhibitor introduced into the feed water if a hardness measured by the hardness analyzer (5) exceeds a first threshold and a water quantity measured by the totalizer (4) is below a second threshold. The controller (9, 209a, 209b) also shifts between the softeners (20, 21) if the measured hardness exceeds the first threshold and the measured water quantity exceeds the second threshold or if the measured hardness is less than the first threshold and the measured water quantity exceeds a third threshold. The second and third thresholds correspond respectively to a fraction and a multiple of the estimated treatment capacity of each of the softeners (20, 21).
摘要翻译：一种包括两个或更多个软水器（20,21）的锅炉给水处理系统（1,100,200），一个用于测量由再生循环之间的每个软化剂（20,21）处理的水量的累加器（4）用于测量由软化剂（20,21）处理的水的硬度的硬度分析器（5），用于将防垢剂引入给水的化学添加剂（7,107）和用于在水中加入防垢剂的控制器（9,20aa，209b）控制系统的运行（1,100,200）。如果由硬度分析仪（5）测量的硬度超过第一阈值，则控制器（9,20aa，209b）控制化学添加剂（7,107）引入或增加引入进料水中的防垢剂的浓度，由累加器（4）测量的水量低于第二阈值。如果测量的硬度超过第一阈值并且测量的水量超过第二阈值，或者如果测量的硬度小于第一阈值，则控制器（9,20aa，209b）也在软化器（20,21）之间移动，水量超过第三阈值。第二和第三阈值分别对应于每个软化剂（20,21）的估计处理能力的分数和倍数。
