Abstract: Provided is a method for cleaning a membrane module provided with a microfiltration membrane and/or an ultrafiltration membrane, and which is used to membrane-filter untreated water to obtain membrane-filtered water. Therein, in order to effectively clean a membrane module while minimizing drops in water recovery rates and chemical costs, and preventing leakages and retention of post-treatment chemical liquids to the secondary side of the membrane module, a chemical diffusion step is performed, in which chemical-containing water is supplied to the primary side of the membrane module, and the chemical is diffused from the primary side to the secondary side of the membrane module. This is followed by a backwash step in which water is backwashed from the secondary side of to the primary side of the membrane module. During the chemical diffusion step, the implementation time for the chemical diffusion step is controlled on the basis of the concentration of the chemical diffused to the secondary side of the membrane module.

Abstract: Disclosed is a method for purifying a process water that can reduce an equipment cost and a running cost in purifying water as a by-product in the production of liquefied hydrocarbons by an FT process to produce water utilizable for various applications. Water as a by-product separated from a reaction product obtained in the production of hydrocarbons using a synthesis gas is subjected to distillation treatment (1) to obtain a primary treated water. The primary treated water is then subjected to cross flow-type semi-permeable membrane separation treatment (2) to obtain a purified water. The purified water may be discharged into rivers, seas or the like. Preferably, however, the purified water is used, for example, as industrial water, irrigation water, and potable water. Concentrated water produced by the semi-permeable membrane separation treatment (2) is biologically treated and is further subjected to solid-liquid separation to purify the concentrated water. The biologically treated water is returned, for example, to the semi-permeable membrane separation treatment (2) to again perform the treatment.

Abstract: A concentration difference power generation device generates power in such a way that high-concentration water and low-concentration water each having a different concentration are contacted each other via a semipermeable membrane unit equipped with a semipermeable membrane and water is made to penetrate from the low-concentration side to the high-concentration side by positive osmotic pressure, resulting in the increased amount of the high-concentration water, which is used for driving a power generator. The concentration difference power generation device is characterized in that the semipermeable membrane unit is divided into a plurality of sub-units (8, 12) and a flow path (L4) on the high-concentration side or a flow path (L3) on the low-concentration side, which leads from the sub-unit (8) of a previous stage to the sub-unit (12) of the next stage, is equipped with a pressure changing mechanism (11).
