摘要： PROBLEM TO BE SOLVED: To provide a passive type pressure control device for controlling the interior of a closed module to the negative pressure very small compared with the atmospheric pressure. SOLUTION: An air buffer 1 is set on a floor surface of an airtight container 2, and contents 11 and 12 connected with the atmospheric side respectively through valves and ducts 9 and 10 connected with the atmospheric closed module on the end of the duct 7 respectively through valves are provided. When atmospheric air is drawn into the air buffer 1 closing valves 3 and 6 and opening valves 4 and 5 and the airtight container 2 is connected with the closed module through the duct 7, the internal pressure of the airtight container 1, namely the interior of the closed module, is retained to negative pressure to the atmospheric pressure at all times by the deformation of a film material caused by the self-weight of the film material of the air buffer 1. Also when the open and closed ends of the valves are reversed and the air buffer 1 is connected with the closed module and the airtight container 2 is opened to the atmosphere, the closed module can be controlled to the positive pressure by the portion of volume fluctuation caused by the self-weight of the film material of the air buffer 1.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of Na ions and Cl ions remaining in solution containing univalent ions and polyvalent ions. SOLUTION: Solution 1 to be separated which is wet oxidizing treated urine contains univalent ions such as Na, K, and Cl and polyvalent ions such as Ca, Mg, SO4 , and PO4 as mineral components. The solution to be separated 1 is mixed with solid or aq. solution of KCl 2 in a mixing tank 3. The solution 1 in the mixing tank 3 is fed to an electrodialysis device 4, and by electrodialysis, it is separated into demineralizecl liquid 5 from which univalent ions have been removed and univalent ion-concentrated liquid 6. When KCl 2 is added to increase the amount of K remaining in the demineralized liquid, the limiting concentration of univalent cations at which polyvalent ions starts to permeate can be lowered, compared with that before KCl addition. In this way, the remaining amount of Na after electrodialysis is reduced, and in order to satisfy electric neutral conditions in the solution, Cl ions are reduced.

摘要： PROBLEM TO BE SOLVED: To lessen the pressure difference between a closed space and the outside air pressure and miniaturize the device as a whole, by absorbing the pressure change of the closed space and keeping it in a certain fine positive pressure, owing to the volumetric chance caused by the movement of the airtight container connected to the closed space, necessitating the protection against the pressure change in the space. SOLUTION: A pressure control system to examine the circulation of substances by plants is constituted of a plurality of rubber buffers 200 absorbing the ordinary outside air pressure change and the pressure change of a plant- cultivation section 100 constituted of a closed space completely cut off from the outside air, by the volumetric change of the movement thereof and a pipe 110 connecting the plant-cultivation section 100 and the rubber buffers 200. The rubber buffer 200 made of chloroprene rubber in which nylon fibers are woven to have flexible and light-weight characteristics absorbs the pressure change of the plant-cultivation section 100 by increasing or dectreasing the volume in a fine pressure difference between the presure in the section and the outside air pressure and keeps the section in a fine positive pressure and prevents the penetration of the outside air.

摘要： PROBLEM TO BE SOLVED: To separately recover high purity NaCl and KCl. SOLUTION: A soln. 11 containing NaCl, KCl and hardly-soluble impurities such as Ca , Mg , SO4 and PO4 is heated in a high temp. crystallization tank 101 to precipitate NaCl and hardly-soluble impurities. The precipitate is separated by a filter 103. The concentrated liquid 14 containing KCl is cooled in a low temp. crystallization tank 301 to precipitate KCl. The precipitated KCl is separated and recovered by a filter 302. The water supplied to the filter 103 dissolves NaCl to recover it and the water is heated in a high temp. crystallization tank 201. The precipitated NaCl is separated by a filter 203 and recovered. Since NaCl and hardly-soluble impurities are separated from the soln. 11 and then NaCl is separated from the hardly-soluble impurities, high purity NaCl and KCl can be separately recovered.
