    • A demand initiated method for regenerating a water softener which operates the softener ion exchange bed over a capacity range in which the resin is most efficiently restored by exposure to brine. The reserve capacity of the softener is adjusted in response to the amount of softening capacity used since the last regeneration, as is the quantity of saturated brine to be used for the next regeneration, which is scheduled when the reserve capacity is exceeded, or the remaining available capacity will not be adequate for expected usage on the next day of the week. The method schedules a regeneration when the amount of exchange capacity of the resin bed used since the last regeneration plus the variation of exchange capacity used on the next day plus the average exchange capacity of the resin bed used on the next day is greater than the selected design exchange capacity.
    • 一种用于再生水软化剂的需求启动方法,其在通过暴露于盐水中最有效地恢复树脂的容量范围内操作软化剂离子交​​换床。 柔软剂的储备能力是根据上一次再生以来使用的软化能量的量进行调节的,以及在超过储备容量时计划的下一次再生时使用的饱和盐水的量,还有剩余量 可用容量将不足以在一周的第二天的预期使用量。 当上次再生后使用的树脂床的交换容量加上第二天使用的交换容量的变化加上第二天使用的树脂床的平均交换容量大于所选择的方法时,该方法进行再生 设计交流能力。

    • An apparatus and method for operating a system of two or more fluid treatment units connected in parallel, which fluid treatment units need to be regenerated as they become depleted, whereby a method is provided for determining when to initiate a regeneration and which unit to regenerate as well as an apparatus for implementing the same. The decision when to regenerate is based on the number of fluid treatment units in service and the fractional capacity of each fluid treatment unit in service. The fluid treatment selected for regeneration is the one with the least or nearly the least remaining capacity. The apparatus comprises a plurality of fluid treatment units; control valves to selectively connect each fluid treatment unit to a source of untreated fluid, a destination for treated fluid, and a source of regenerant; and a master controller to automatically implement the method of operation by controlling the valves appropriately.
    • 一种用于操作并联连接的两个或多个流体处理单元的系统的装置和方法,当流体处理单元耗尽时,需要再生该流体处理单元,由此提供了一种用于确定何时开始再生的方法以及哪个单元被再生为 以及实施相同的设备。 重新生产的决定是基于正在使用的流体处理单元的数量和使用中的每个流体处理单元的分数容量。 选择用于再生的流体处理是具有最少或几乎最小剩余容量的流体处理。 该装置包括多个流体处理单元; 控制阀选择性地将每个流体处理单元连接到未处理流体源,处理流体的目的地和再生剂源; 以及主控制器,通过适当地控制阀来自动实现操作方法。
