摘要： While productivity in generation of treated water is improved, a membrane cleaning effect through relaxation is sufficiently exerted. While aeration is carried out with respect to at least one membrane cartridge (18), a cycle of a filtration operation and a filtration stoppage operation is repeated. A gas vent valve (62) connected to a gas retention chamber (52) is used, and the gas vent valve (62) is opened and then closed in accordance with a timing of start of the filtration stoppage operation in each cycle.

摘要： An object of the present invention is to provide a specific method for determining the fouling potential of an activated sludge solution on the basis of the characteristics of the activated sludge solution after chemical cleaning of a membrane, and to provide a suitable method for resuming operation in a rational manner after chemical cleaning of the membrane, while accurately determining the degree of recovery of the membrane filtration characteristics for the activated sludge solution. Moreover, an object of applying the present invention is to enable more effective suppression of an increase in a transmembrane pressure difference after chemical cleaning than in the prior art, leading to a reduction in the cleaning frequency of the membrane and a reduction in the used amount of cleaning chemicals and to extension of the life of the membrane.
The present invention relates to a method for operating a membrane-separation activated sludge treatment device after chemical cleaning of a membrane, the method including, after the chemical cleaning of the membrane is completed, controlling an operating condition until a normal filtration operation is resumed on the basis of characteristics of an activated sludge solution.

摘要： A method of operating a filtration unit of a filtration system includes



feeding, during filtration, feed water containing suspended particulate material to an inside of each of a plurality of hollow fibres through a first inlet and a second inlet of each hollow fibre while simultaneously removing a filtrate from an outside of each of the hollow fibres through an outlet of a filtration elements. In addition, the method includes feeding,
during back-washing, back-wash water to the outside of the hollow fibres through the outlet of the filtration element. Further the method includes discharging, in a first back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from one end thereof. Still further, the method includes discharging, in a second back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from the other end thereof.
