    • A method is provided for the continuous production of treated waters using a staged, tapered array membrane plant by a process of process-logic-controlled (PLC) stage or stage increment isolation and removal from service, washing and return-toservice concurrent with the continued operation of all other stages and/or stage increments of the plant. Specifically, there are plant mounted input/output sensors that supply the PLC with the data required to identify the location and degree of "fouling" of the individual stages or stage increments of a tapered array membranevater treatment plant, where fouling is defined as a loss of water flow through a membrane surface at a given pressure when compared to a water flow standard for the surface. When a stage or stage increment of a plant is defined by this process to be "fouled," the PLC commands the initiation of a sequence of automated valve openings and closings to a) remove the fouled stage or stage increment from feed water treatment service, b) to flush and wash the stage or stage increment, and c) to return the stage or stage increment to feed water treatment service. Optionally the PLC function can be extended to include the monitoring and control of ancillary valves and a variable­frequency-drive feed water pump to command the parts of a plant that remain on-line during the process of a stage or stage increment wash to continue to produce more, or less, or volumetrically identical amounts of membrane water treatment process permeate by combinations of valve re­settings, pump speed adjustments, and stage-to-stage intermediate water diversion.
    • 提供了一种方法,用于通过过程逻辑控制(PLC)阶段或阶段增量隔离和从服务,洗涤和返回服务的过程中连续生产处理过的水,并使用持续的 所有其他阶段的操作和/或工厂的阶段增量。 具体来说,有工厂安装的输入/输出传感器,为PLC提供识别锥形阵列隔膜处理厂的各个阶段或阶段增量的“结垢”的位置和程度所需的数据,其中结垢被定义为损失 当与表面的水流标准相比时,水在给定压力下流过膜表面。 当工厂的阶段或阶段增量由该过程定义为“污染”时,PLC命令启动一系列自动阀门开启和关闭,以便a)从给水处理服务中移除污染阶段或阶段增量, b)冲洗和冲洗阶段或阶段增量,以及c)使阶段或阶段增量返回给水处理服务。 可选地,PLC功能可以扩展到包括辅助阀的监控和控制以及变频驱动给水泵,以指令在阶段或阶段增量清洗过程中保持在线的工厂的部件继续产生 更多或更少或体积相等的膜水处理过程通过阀复位,泵速调节和阶段到阶段中间分水的组合渗透。

    • A membrane treatment plant having at least two stages (53), (69), (75) arranged serially is disclosed. Each stage (53), (69), (75) comprises at least four membrane units (55) arranged in parallel, with each membrane unit (55) having an inlet (57), a feed/concentrate outlet (59) and a permeate outlet (61). Each stage (53), (69), (75) has a common inlet header (51), (67), or (73) and a common outlet header (65), (71), or (77), with the common outlet header (65) (71) of an upstream stage connecting to the common inlet header (67) (73) respectively of an immediately downstream stage. Each membrane unit (55) has an inlet flow control valve (93) connecting between its inlet (57) and the common inlet header of the stage in which it is located, and an outlet flow control valve (63) connecting between its outlet (59) and the common outlet header of the stage in which it is located. The inlet flow control valve (57) and outlet flow control valve (63) are operable to isolate the membrane unit (55) from its common inlet header and common outlet header to allow cleaning of said membrane unit to take place without disrupting operation of the remaining membrane treatment plant. A control system for the membrane treatment plant is also disclosed.
