摘要： PROBLEM TO BE SOLVED: To surely detect sea water leak by deaeration-processing condensed water before detection of conductivity of the condensed water for removing carbon dioxide gas dissolved in the condensed water by deaeration, so that malfunction due to vacuum break, etc., of a condenser is prevented. SOLUTION: A detection device 10, with a water-intake pipe 11 connected to a condenser 20 in between, a comprises a conveying pump 12, a column 13 filled with H-type cation exchange resin which ion-exchanges with cation H , a film deaeration device 14 deaerating the dissolved carbon dioxide gas, and an acid conductivity meter 15 assigned on the poststage of the device 14. The pump 12, the column 13 and the film deaeration device 14 are connected from upstream side to downstream side in this order with the water-intake pipe 11 in between. The condensed water is taken in through a valve 16 assigned on the upstream side of the pump 12. The film deaeration device 14 comprises a hollow yarn module 141 and a vacuum pump 143, acting as an evacuation device, which is connected with a vacuum piping 142 in between. From relation between degree of vacuum of the module 141 and resistivity of pure water containing dissolved carbon dioxide gas at the degree of vacuum, degree of vacuum not exceeding about 45Torr is obtained.

摘要： PURPOSE:To simplify an apparatus and enhance function by integrating a bioreactor, a diffuser and a separated membrane module. CONSTITUTION:After being sent from a raw water tank 1 to a bioreactor 2, raw water is treated biochemically under aerobic microbic conditions. Next, by actuating a vacuum pump 14, a suction is carried out from the bioreactor 2 to a vacuum tank 8 for water to be treated through a separated membrane module 3. By said process, solid content is removed, and only filtered treating water is sucked and drained. When treating water is stored in the vacuum tank 8 up to water level to be detected by a level switch 21, treating water discharge valve 7 and a vacuum pump connecting valve 12 are closed and a discharge valve 2 is opened to drain out treating water down to a treating water tank 19. Thus an apparatus is simplified and the cost is reduced.

摘要： PURPOSE:To recover ion exchange rate, by a method wherein a highly basic anion exchange resin used in a condensate desalting device and lowered in ion exchange rate is treated with an organic solvent. CONSTITUTION:The highly basic anion exchange resin used in the condensate desalting device and lowered in ion exchange rate is treated with an organic solvent such as acetone and carbon tetrachloride to recover the ion exchange rate. The amount of the solvent is ordinarily 5-10 times (by volume) of the amount of the resin, and a circulating system is more effective than a one- through system. In addition, the desorbing effect is higher at about 50 deg.C than at normal temperature. When the resin is treated with an acid such as hydrochloric acid before or after passing the organic solvent, an effect of desorbing contaminants is enhanced. When the resin in treated with an organic solvent containing an acid such as hydrochloric acid, the contaminants can be desorbed more effectively as compared with the case of treating the resin solely with the organic solvent.

摘要： PURPOSE:To unnecessitate a large-size reservation tank for aeration with using inert gas by supplying gas which substantially contains no gas to be removed dissolving in the objective liquid to the liquid supply line in the preceding stage of a membrane deaeration device so that the gas is dissolved in the liquid in the supply line. CONSTITUTION:The dissolving gas in a liquid is removed by a membrane deaeration device 3 using a deaeration membrane 4. In this process, gas (inert gas) which substantially contains no gas to be removed dissolving in the objective liquid is supplied from the source 9 through a supply tube 10 to the liquid supply line 1 in the preceding stage of the membrane deaeration device 3. Thereby, the gas from the supply tube 10 is dissolved in the liquid in the supply line.

摘要： PURPOSE:To separate and concentrate effectively an alcohol from an aqueous solution of the alcohol to the permeated water side at a relatively low energy cost, by feeding the aqueous solution of the alcohol containing a soluble organic substance other than the alcohol to a reverse osmosis membrane of relatively low desalination ratio under pressure. CONSTITUTION:An alcohol is separated and concentrated from an aqueous solution thereof 2. In the process, a soluble organic substance 3, e.g. raffinose or lactose, other than the alcohol is present in the above-mentioned aqueous solution 2, which is fed to a reverse osmosis membrane 5 of pressure to separate and concentrate the alcohol 6 on the permeated water side. The alcohol can be concentrated under a lower pressure by this method than by the well-known method, and this method is advantageous to energy cost. The unpermeated water side 7 is circulated, and a concentrated solution of the alcohol 6 is obtained on the permeated water side. Thus, the recovery ratio of the alcohol is high, and an aqueous solution of a lower alcohol in a low concentration at which the distillation method cannot be applied can be concentrated to a concentration at which the distillation method is applicable at a low cost.

摘要： PURPOSE:To provide a working liquid supply device which can lengthen the life of an ion exchange resin layer used in the working liquid supply device for discharge machining. CONSTITUTION:A film deaerator 8 and/or 8' is provided in a circulating line of a water-base working fluid W. A water-base working fluid which does not contain an anticorrosive agent or contains a small quantity of the anticorrosive agent is used, and discharge machining is performed using a working fluid W obtained by at least partially removing dissolved oxygen and carbon dioxide in the working fluid W by the film deaerator. Accordingly, comlicatedness due to maintenance such as the supply of an anticorrosive agent or the like can be avoided.

摘要： PURPOSE:To prevent a lowering of water quality by combining a membrane degassing apparatus equipped with a water repellent membrane for degassing dissolved gas with a two-step type reverse osmosis membrane apparatus. CONSTITUTION:Pretreated raw water is supplied to a membrane degassing apparatus 6 through a raw water inflow pipe 12. The acid such as hydrochloric acid in an acid storage tank 1 is injected in the raw water before reaching the membrane degassing apparatus 6 by driving an acid injection pump 2 to be mixed therewith by a line mixer 3 to adjust the pH of the raw water after mixing to 5.5 or less. After a part of a carbonic acid ion present in the raw water is changed to carbon dioxide, the raw water is treated with the membrane degassing apparatus 6. The membrane degassing apparatus 6 is divided by a water repellent membrane 7 and the raw water containing dissolved gas such as carbon dioxide is passed through one chamber and the dissolved gas in the raw water is passed through the water repellent membrane 7 to perform degassing. By this method, high purity desalted water is obtained stably.

摘要： PURPOSE:To efficiently remove the gas dissolved in boiler water in a water supply line by providing an ejector in the pipeline of a return pipe and allowing the suction side of said ejector to communicate with the water non-contact side of a membrane degassing device. CONSTITUTION:The boiler water reduced in the amount of dissolved gas stored in a water storage tank 1 is guided to a membrane degassing device 6 through a water supply line by operating a boiler water supply pump 4. A part of the degassed boiler water supplied to a boiler 5 by the boiler water supply pump 4 is returned to the water storage tank 1 by the return pipe 7 provided in the water supply line. when the return water passes through the ejector 9 provided in the pipeline of the return pipe 7, the membrane degassing device 6 is sucked on the water non-contact side thereof. As mentioned above, since the membrane degassing device 6 is sucked on the water non-contact side of a water repellent membrane thereof by the ejector 9, the very small amount of the dissolved gas in the boiler water transmits and passes through the membrane to be removed from the boiler water.
