    • The invention relates to a method for treatment of liquid, that is meant particularly for filtering of pressurized liquid, such as water led from a water distribution system, by means of an apparatus, which has an essentially closed frame (1), in connection with which there has been arranged at least filtering means (2) for purifying of liquid and flow means (3), such as feed-flow and/or exhaust flow arrangements (3a, 3b) for leading of liquid. The filtering means (2) are made of thin filtering film (2a), advantageously made of plastic based material, such as PTM (Particle Track Membrane), TeM (Track-etch Membrane) or like, the thickness of which is preferably 7-25 mu m and the size of pores of which is 0,05-10 mu m. The filtering film (2a) belonging to filtering means (2) are being purified essentially self-powered, such as by means of purification means (5) exploiting the pressure (p), the movement (v1) and/or like of the liquid to be treated and/or the liquid that has been treated. The invention relates to an apparatus operating according to the method as well.
    • 本发明涉及一种用于处理液体的方法,特别是用于通过装置过滤加压液体,例如从配水系统引出的水,该装置具有基本上封闭的框架(1),与 其至少布置有用于净化液体的过滤装置(2)和用于引导液体的进料流和/或排气流动装置(3a,3b)的流动装置(3)。 过滤装置(2)由薄过滤膜(2a)制成,有利地由诸如PTM(粒子轨道膜),TeM(轨道蚀刻膜)等的塑料基材料制成,其厚度优选为7- 25亩,毛孔大小为0.05-10亩。 属于过滤装置(2)的过滤膜(2a)基本上被自动净化,例如通过使用压力(p),液体(v)和/或类似液体的纯化装置(5) 待处理和/或经过处理的液体。 本发明还涉及根据该方法操作的设备。

    • A filtration apparatus is provided, of the type that includes a stack of rapidly rotating membrane packs (32) and a stack of stationary separator elements (36A, 36B) interleaved with the membrane packs to leave thin gaps (40A, 40B) between them, which obtains the advantages of both series-connected and parallel-connected systems. A feed conduit (82) connects the radially outer ends (110) of the gaps, to carry feed fluid into and out of each gap. The rapidly rotating membrane packs cause radially outward flow near their surfaces, which causes radially inward flow (102) near the surfaces of the stationary elements, to cause fluid flow radially inwardly and then outwardly through each gap. The stationary elements have apertures (131-138) to equalize the pressure on opposite sides thereof and to promote fluid shear at the membrane surfaces. An accumulator (140) is coupled to the feed inlet (12) to maintain feed fluid pressure during an abnormal loss of feed fluid pressure, for the time required to stop rotation of the stack of membrane packs.
    • 提供了一种过滤装置,其类型包括快速旋转的膜组件(32)和与膜组件交错的固定分离器元件(36A,36B)的堆叠,以在它们之间留下薄的间隙(40A,40B) 获得串联和并联系统的优点。 进料管道(82)连接间隙的径向外端(110),以将进料流体输送进出每个间隙。 快速旋转的膜组件在其表面附近引起径向向外的流动,这在静止元件的表面附近引起径向向内的流动(102),以使流体径向向内流动,然后通过每个间隙向外流动。 固定元件具有孔(131-138)以使其相对侧上的压力相等并且促进膜表面处的流体剪切。 蓄能器(140)联接到进料入口(12),以在进料流体压力的异常损失期间保持进料流体压力,持续停止膜组件的旋转所需的时间。
