    • A method and a magnetic levitation vehicle operating with this method are described. For the control of support gaps (10a, 10b) that are formed during operation of the magnetic levitation vehicle (1) between a track (2, 3, 4) and a number of carrying magnets (6a, 6b) fastened to said magnetic levitation vehicle (1) and provided with windings (16a, 16b), wherein at least two carrying magnets (6a, 6b) in adjacent positions act upon a suspension frame (8) of said magnetic levitation vehicle (1), the electrical currents flowing through the windings (16a, 16b) are so controlled that the support gaps (10a, 10b) between these two carrying magnets (6a, 6b) and the track (2, 3, 4) adopt pre-determined nominal values (na, nb). In accordance with the invention and in case that the currents through the windings (16a, 16b) of the adjacent carrying magnets (6a) are different under normal conditions, the nominal values (na, nb) for the support gaps (10a, 10b) are altered such that the current through the windings (16a or 16b) of a carrying magnet (6a, 6b) with the lower electric current is increased and/or the electric current through the winding (16b and/or 16a) of a carrying magnet (6b, 6a) with the larger electric current is reduced.

    • A continuous integrity test is performed on membranes in a membrane filtration system during the backwashing phase. The membrane pores are backwashed by applying a gas at a pressure below the bubble point to liquid permeate within the membrane lumens to displace the liquid permeate within the lumens through the membrane pores. An integrity test is performed on the membranes by allowing the gas pressure on the lumen side of the membrane walls to increase to a predetermined level above the pressure on the other side of the membrane walls, then isolating the lumen side of the membranes and measuring the reduction in gas pressure on the lumen side of the membrane walls resulting from gas passing through the membrane walls over a predetermined period. The measured reduction in pressure is then compared against a predetermined value to determine the integrity of said membranes.
    • 在反冲洗阶段期间,在膜过滤系统中的膜上进行连续完整性测试。 通过将低于起泡点的压力施加气体到膜腔内的液体渗透物来回流膜孔,以通过膜孔移动腔内的液体渗透物。 通过使膜壁的内腔侧的气体压力增加到高于膜壁另一侧的压力的预定水平,然后隔离膜的内腔侧面并测量 在预定的时间内,气体通过膜壁导致的膜壁的管腔侧的气压降低。 然后将测量的压力降低与预定值进行比较以确定所述膜的完整性。
