摘要： Modules of ultrafiltration or microfiltration membranes are arranged in a tank open to the atmosphere to substantially cover the cross sectional area of the tank. A filtration cycle has permeation steps and deconcentration steps. During permeation, supply of feed substantially equals feed removed and little if any aeration is used. During deconcentration, aeration with scouring bubbles is provided with one or both of backwashing and feed flushing. In feed flushing, feed water is supplied to the tank from below the modules. Excess tank water created during deconcentration flows generally upwards through the modules and out through a retentate outlet or overflow at the top of the tank.

摘要： An element for use in ultrafiltration or microfiltration of potable water has a large number of small diameter hollow fibre membranes attached between two headers. Side plates attached to the sides of the headers define vertical flow channels containing the membranes. The elements may be placed side by side and stacked on top of each other to form cassettes having continuous vertical flow channels through the entire cassette. The membrane modules or cassettes may be arranged to cover a substantial part of the cross sectional area of an open tank. Tank water may flow upwards or downwards through the flow channels. A tank may be deconcentrated by at least partially emptying and refilling the tank with fresh water while permeation continues. Excess tank water created during deconcentration may flow generally upwards through the modules and out through a retentate outlet or overflow at the top of the tank.

摘要： An improvement to an outside/in hollow fiber membrane filtration system includes a source of suction on the lumens of the membranes or pressure on the outside of the membranes operable without producing permeate and an air collector to collect any air that passes from the outside of the membranes to their lumens during an integrity test. A method for testing the integrity of filtering membranes involves exposing a first side of the membranes to air while a second side of the membranes remains exposed to water. A transmembrane pressure forces air through defects of concern in the membranes. Air that passes through a set of membranes is collected and its amount measured and compared to an acceptable amount of air to indicate whether there is a defect in the set of membranes. Preferably, air is collected individually from a plurality of membrane units in a filtration train and the amounts so collected compared to indicate if one of the membrane units is defective.

摘要： A process for operating filtering membranes submerged in a tank involves, in one aspect, periodically deconcentrating the tank by at least partially emptying and refilling the tank with fresh water while permeation continues. In another aspect, long trains of membranes modules are placed in series along a flow path in the tank. In one embodiment, constant aeration is provided to prevent tank water from by-passing the membrane modules while proving controlled mixing such that the average concentration of solids in the tank is lower than the concentration of solids in the tank near an outlet for removing retentate from the tank. In another embodiment, the membrane modules are arranged in a series of filtration zones between a feed water inlet and a retentate outlet of a tank. Permeate is withdrawn from the filtration zones by separate means associated with each filtration zone. Tank water containing rejected solids flows in a tank flow through the filtration zones, increasing in concentration from one zone to the next. A preferred membrane module has membranes transverse to the tank flow and fills a substantial portion of each filtration zone. With either embodiment, aeration, backwashing or packing density of membranes varies between filtration zones and the flow pattern in the tank may be periodically reversed.

摘要： In an apparatus for providing a continuous integrity test for suction driven filtering membrane assemblies 10, a monitoring line 32 diverts a portion of permeate to a monitoring device 30 (e.g. a turbidimeter). Both ends 34, 36 of the monitoring line are connected to the permeate pipe 20 upstream from the permeate pump 26 and at points of relatively higher and lower pressures respectively, to cause fluid to flow through the monitoring line. The relatively higher and lower pressures may be caused by a source of head loss 38 (e.g. a valve) in the permeate line. The source of head loss may be adjusted to provide a required flow through the monitoring device by a control 43 communicating with a flow meter 42 in the monitoring line. Membrane assemblies may be individually monitored although many of them may be connected to a common permeate pump (FIG. 2).
摘要翻译：在用于为抽吸驱动的过滤膜组件10提供连续完整性测试的装置中，监测管线32将一部分渗透物转移到监测装置30（例如浊度计）。监测管路的两端34,36分别在渗透泵26的上游和相对较高和较低压力的点连接到渗透管20，以使流体流过监测管线。相对较高和较低的压力可能由渗透管线中的头部损失源38（例如阀）引起。可以调节头部损失的来源，以通过与监视线路中的流量计42通信的控制器43来提供通过监视装置的所需流量。但是可以单独地监视膜组件，尽管它们中的许多可以连接到共同的渗透泵（图2）。
