SOLUTION: This machine has the means 9 for pumping up the raw water and boosting the raw water to the high pressure. The means bypasses the raw water without functioning in case the means receives the supply of the pressurized raw water from a portable type engine pump 24, etc. The front of a hose is provided with a strainer 1 as an intake port for the raw water and is provided with a float 3 for setting the raw water intake port at a prescribed depth of water. In addition, the strainer is detained to an anchor 7 by means of a rope 6. A prefilter 11 of a fiber winding type and a reverse osmosis membrane module unit 14 are successively disposed in the raw water piping 10. A sterilizing agent in a sterilizing agent bottle 23 is sucked out through a sterilizing agent tube 21 to an aspirator 20 and is incorporated into the produced water at the time of water feeding.

Abstract: PURPOSE:To securely detect leakage of cooling water to the condenser even when the generator is not operating by a method wherein the condensate is treated with a cation exchange resin, this condensate is made to undergo decarbonation by contact with a gas from which carbonic acid gas has preliminarily been removed, and then the electric conductivity of the condensate is measured. CONSTITUTION:From a condenser 1 a portion of the condensate is drawn off as a sample of water by a water-sampling pump 2. The sample of water thus drawn off is put into the lower part of a cation exchange resin tower 3 and treated with a cation exchange resin so as to remove the cations from the sample of water by exchange of cations. Subsequently to the exchange of cations the sample of water is put into the upper part of a gas-permeable hydrophobic membrane module 4, whereas a gas 6 from which carbonic acid gas has preliminarily been removed is put into the hydrophobic membrane module 4 from below; by contact of the sample of water with the gas 6 in a manner of counterflow the carbonic acid in the sample of water is removed. After the decarbonation, the electric conductivity of the sample of water is measured by the use of a conductivity meter 5 to detect from the value of the measurement whether there is anything abnormal or not.
