摘要： The discharge of copper from isothiazolone biocides into industrial waste water streams is prevented by contacting the isothiazolone biocide as it is withdrawn from a point of use storage container with an ion exchange resin capable of removing copper from aqueous solutions. When the treated isothiazolone biocide is added to an industrial process water which will produce waste stream, potential copper contamination is virtually eliminated.
摘要翻译：将异噻唑酮杀生物剂排出到工业废水流中可以通过使异噻唑酮杀生物剂从一个使用的储存容器中取出并与能够从水溶液中除去铜的离子交换树脂接触来防止。当将经处理的异噻唑酮杀生物剂加入到产生废物流的工业过程中时，几乎可以消除潜在的铜污染。

摘要： Leakage of water from a boiler water system wherein steam is generated in a boiler from feedwater fed to the boiler, and the concentration of impurities in the boiler water within the boiler is reduced by withdrawing fractions thereof as blowdown while admitting additional feedwater as boiler-water makeup, is determined. The boiler has a concentration cycle value, the concentration cycle value being the average value of the concentration of an inert component in the blowdown at steady state (C.sub.F) divided by the concentration of the inert component in the feedwater (C.sub.I). The concentration of the inert component in the boiler at steady state varies from a high concentration C.sub.H, having a value that is higher than C.sub.F, to a low concentration C.sub.L, having a value between the (C.sub.I) and the (C.sub.F), within a time period. The method comprises:employing as the inert component an inert tracer;sensing a characteristic of the inert tracer in the boiler at steady state equivalent to its concentration in the boiler water;converting the sensed characteristic to a value equivalent to the concentration of the inert tracer in the boiler water; andactivation of a signal when a variance in the cyclic concentration fluctuation of said inert tracer occurs that is consistent with a leakage of boiler water.
摘要翻译：来自锅炉水系统的水的泄漏，其中在锅炉中从供给到锅炉的给水中产生蒸汽，并且通过将其作为排放物的馏分取出而将锅炉水中的杂质浓度降低，同时允许另外的给水作为锅炉水化妆，确定。锅炉具有浓度循环值，浓度循环值是在稳定排放（CF）中的惰性组分的浓度除以给水（CI）中的惰性组分的浓度的平均值。在稳定状态下锅炉中的惰性组分的浓度从具有高于CF的高浓度CH与具有（CI）和（CF）之间的值的低浓度CL在一个时间段。该方法包括：将惰性组分用作惰性示踪剂; 感测锅炉中惰性示踪剂的特性，其稳定状态等于其在锅炉水中的浓度; 将感测特性转换成与锅炉水中的惰性示踪剂的浓度相当的值; 当所述惰性示踪剂的循环浓度波动的变化发生与锅炉水的泄漏一致时，激活信号。
