摘要： PURPOSE:To enable service water to be circulatedly used without providing a dust-removing tank or a settling tank by circulating hot water in wide shallow flow passages formed both by a thin flat plate whose upper surface is made to be a heat-radiating surface and by a corrugated thin plate provided under the flat plate. CONSTITUTION:To the undersurface of a thin flat plate 13 whose upper surface is made to be heat-radiating surface, a corrugated thin plate 14 having continuous recessed parts consisting both of a plurality of rows of wide shallow recessed parts and of wide shallow recessed parts connecting the adjacent rows of the above recessed parts is joined. At both ends of the wide narrow flow passages 11 formed both by the continuous recessed parts of the corrugated thin plate 14 and by the flat plate 13, piping connecting ports are provided. And by circulating hot water or the like in the inside of these flow passages 11, snow on the flat plate is heated through indirect contact, and is melted.

摘要： PURPOSE:To make the title membrane separator compact by connecting the liq. concentrate outlet from the membrane separation unit, in which a check valve plug provided with a membrane face cleaner is inserted into each internal pressure type tubular membrane, to the suction port of a reciprocating pump, and providing a check valve seat at the inlet for the raw liq. to be treated. CONSTITUTION:Compressed air from a compressor 45 is supplied alternately into the air chambers 30 on both sides to operate the reciprocating pump 7. In the suction stage of the pump 7, the check value plug 3 provided with a membrane face cleaner 2 is pressed by the flow of the raw liq. 40 sucked into the internal pressure type tubular membrane 1 from the inlet 8 for the liq. to be treated, and lifted up while cleaning the membrane face. The raw liq. is further sucked into a pump chamber 31. In the discharge stage of the pump 7, the inside of the pump chamber 31 is pressurized, and the check valve plug 3 is pressed down while again cleaning the membrane face by the back flow of the raw liq. The check valve 3 then abuts on the check valve seat 9 and stops. Since the inlet 8 is closed and the inside of the membrane 1 is pressurized, the raw liq. permeates through the membrane 1 from the inside to the outside, and the permeated liq. flows out from a discharge pipe 39. The liq. concentrate returns to a raw liq. tank 41 from a discharge port 26.

摘要： PURPOSE:To provide an effective utilization of latent heat of ice in a cooling load and prevent an ice from being changed into a block by a method wherein ice pieces and cold water are stored in the same thermal accumulating tank and all the ice pieces are mixed with cold water and then both ice pieces and cold water are transported. CONSTITUTION:When ices are made at night, thermal accumulated water 11 in a thermal accumulating tank 1 from a water pipe passage 6 is continuously changed into some ice pieces 13 by an ice making machine 5 and then the ice pieces are discharged from a lower part of the thermal accumulating tank 1 into thermal accumulating water through a water feeding pipe passage 2. The ice pieces 13 are immersed in a part below an ice making plate 4A and then the ices are stored there. When a cooling load is to be required at daytime, an ice feeding machine 3A in an ice discharging pipe passage 3 and a pump 8 are operated. Cold water 12 and ice pieces 13 are formed continuously into mixed cold water and they are fed to a cooling pipe 9. Hot water return water is returned back into the thermal accumulating tank 1 through a return water pipe 10. In addition, the ice pieces are stored while being floated, and then a transporting of the ices may easily be carried out. With such an arrangement, it is possible to provide an effective utilization of latent heat of ice and to prevent some ice pieces from being formed into ice blocks.

摘要： PURPOSE:To efficiently carry out the tertiary treatment of sewage at a low running cost and at a high treating rate, by directly filtering secondarily treated sewage with a sand filter, and again filtering the filtrate with a precoat filter. CONSTITUTION:Sewage is biologically treated to obtain secondary treated water, the treated water is further completely treated by reverse-osmosis treatment, and clarified water is obtained. In this case, the secondary treated water is directly sand-filtered, and then again filtered by a precoat filter as the pretreatment for the reverse-osmosis treatment. For example, the secondary treated water 1 is sucked up by a submersible pump P1, introduced into a plural-layered rapid sand 2, and filtered. The sand-filtered water 3 is introduced into the precoat filter 4, a precoat slurry tank 16 is simultaneously filled with the sand-filtered water 3 to prepare for the precoat, a filter aid 8 such as the fine powder from a blast furnace is precoated on a leaf 5, and filtration is started. The tertiary treated water 11 is forced into a reverse-osmosis membrane 13.
