摘要： An anion adsorbent comprising a fired clay of porous structure and, supported thereby, a rare earth compound. This anion adsorbent is produced by a process comprising the mixing step of mixing a clay with an auxiliary agent for realization of porous structure, the firing step of firing the mixture obtained by the mixing step and the supporting step of causing the clay prior to the mixing step and/or the firing product after the firing step to support a rare earth compound. There is further provided a method of water treatment, comprising bringing this anion adsorbent into contact with water to be treated at given pH value to thereby adsorb and remove anions contained in the water and bringing the adsorbent after adsorption of anions into contact a solution of pH value different from the given pH value to thereby effect desorption of anions from the adsorbent.

摘要： PROBLEM TO BE SOLVED: To provide a device for cooling water and a method for treating cooling water capable of surely preventing scales from growing even at a place of a low flow rate in a cooling water line. SOLUTION: The inside of an electrolytic device 1 is divided into an anode chamber 2 and a cathode chamber 3 by a diaphragm 6, an anode 4 is installed in the anode chamber 2, and a cathode 5 in the cathode chamber 3. Cooling water or resupply water is introduced into the anode chamber 2 from a pipe 1a through a pipe 1b, introduced into the cathode chamber 3 from the pipe 1a through a pipe 1c and flowed out from the anode chamber 2 through a pipe 1d. A part of alkaline water generated in the cathode chamber 3 is discharged to the outside of a system through a pipe 1e. The anode 4 and the cathode 5 are applied by voltage through an electric current control device 11. Water passing through the anode chamber 2 is prevented from occurring of scales in a water circulation system since the concentration of metal ions such as Ca ions and Mg ions are reduced with lowering of pH.

摘要： PROBLEM TO BE SOLVED: To provide a scaling preventing method capable of preventing the precipitation of scale mainly comprising metal ions such as calcium and magnesium or silica dissolved in water to be treated by electrolysis and reducing the consumption amount of electrolytic electrodes. SOLUTION: In this scaling preventing method for preventing the precipitation of scale from water, water is electrolyzed using a carbon material as electrodes to form not only fine particles of carbonates of metal ions dissolved in the water but also a scaling preventing component by electrolysis to add the scaling preventing component to the water. Water to be treated passes through a gap between the electrodes of a scaling preventing device. Fine particles of the scale component are formed in the high pH region in the vicinity of the cathode. An aromatic carboxylic acid is formed as the scaling preventing component from the anode. The gap between the electrodes is controlled correspondingly to the quality of water to be treated.

摘要： PROBLEM TO BE SOLVED: To efficiently perform scale deposition in an electrolyzer for reducing scale generating tendency; to perform removing and cleaning of scale sufficiently at a low cost.
SOLUTION: A main electrolyzer 2 for reducing the scale generating tendency is installed in piping 1 for cooling water. In the main electrolyzer 2, an anode 5a and a cathode 5b made of a porous body are disposed opposite to each other in a casing 3. A sub-electrolyzer 11 for generating acidic water for acid cleaning of the main electrolyzer 2 is installed. In the sub-electrolyzer 11, its inside is divided into an anode chamber 12 and a cathode chamber 13 by a diaphragm 16, and an anode 14 is installed in the anode chamber 12 and a cathode 15 is installed in the cathode chamber 13. When the operation of the main electrolyzer 2 continues, the scale adheres to the cathode in it, so that the main electrolyzer 2 is acid cleaned periodically or when current-carrying resistance between the electrodes exceeds the prescribed value.

摘要： PROBLEM TO BE SOLVED: To provide a scale prevention apparatus by which scale growth is surely prevented even at a part where a flow rate is slow in a circulation cooling water line or a boiler line or the like. SOLUTION: In a 1st electrolysis section 11, a zone surrounded by a diaphragm 8 is formed near an anode 4 and polymer particles 6 are filled in this zone. In a 2nd electrolysis section 12, a water flowing space where no particle is filled is formed between the anode 4 and the cathode 5. Scale of a particulate shape is produced at cathode sides in both the 1st electrolysis section 11 and the 2nd electrolysis section 12 and the particulate is made to flow in the circulation cooling water line while being mixed with the cooling water. Organic components eluted from the polymer particle 6 or produced by decomposition of the polymer particle are adsorbed by the particulate. Thereby especially activity of a growing point (a kink) of the particulate falls and the particulate is prevented from excessively growing. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a water supply treatment apparatus capable of obtaining a decarbonization effect equal to that of a conventional acid and alkali adding method without using chemicals.
SOLUTION: An electrolytic cell 1 is internally demarcated into an anode chamber 2 and a cathode chamber 3 by a diaphragm 6 and an anode 4 is installed in the anode chamber 2 while a cathode 5 is installed in the cathode chamber 3. Water to be supplied or replenishing water is introduced into the anode chamber 2 through piping 1a to flow out of the anode chamber 2 through piping 1b. Voltage is applied across the anode 4 and the cathode 5 from a power supply 10 through a current controller 11. Since the water having passed through the anode chamber 2 has acidic pH, decarbonization treatment is performed in a degassing device 20. Alkali water from the electrolytic cell 1 is added to this acidic water after decarbonization treatment to obtain neutral or alkaline treated water.
