Modes for Carrying Out the Invention

[0018] Hereinafter, embodiments will be described with reference to the drawings.

[0019] FIG. 1 is an exploded perspective view of a water channel board 1 according to an embodiment. This water channel board 1 has a board body 2 provided with a plurality of water channel grooves A to H on one board surface, and a flat plate 3 that is overlapped on the one board surface of the board body 2.

[0020] The flat plate 3 is provided with water channel holes formed by small holes at positions overlapping the water channel grooves described later, and nozzles 4 are provided coaxially with the water channel holes. Each nozzle 4 is a one-touch joint nozzle, and a coupler (not shown) of the one-touch joint is detachable. Each nozzle 4 projects on the side opposite to the board body 2.

[0021] The water channel groove A has a vertical water channel groove s5 extending in the vertical direction, and four horizontal water channel grooves s1, s2, s3, s4 that are connected at right angles to the water channel groove s5 and extend horizontally. The nozzles 4 overlap the tips of the horizontal water channel grooves s1 to s4 respectively, thereby forming water inlets and outlets a1, a2, a3, a4.

[0022] Channel B is an L-shaped structure consisting of a horizontal channel and a vertical channel. Water inlets and outlets b1 and b2 are formed at the tip of the horizontal channel and at the lower end of the vertical channel, respectively.

[0023] The drainage channel C has a lateral drainage channel, a vertical drainage channel connected to one end of the lateral drainage channel, and a U-shaped drainage channel connected to the lower end of the vertical drainage channel. Three entrances and exits c1, c2, and c3 are formed in this drainage channel C.

[0024] The channel D has a channel extending in the vertical direction, a channel extending in an L-shape with one end connected to the middle of the vertical channel, and a T-shaped channel extending in a horizontal T-shape connected to the lower end of the vertical channel. Water inlets and outlets d1, d2, d3, and d4 are formed in this channel D.

[0025] The water channel E extends in a horizontal T-shape, and water inlets and outlets e1, e2, and e3 are formed there.

[0026] The water channel F extends in a horizontal F-shape, and water inlets and outlets f1, f2, and f3 are formed there.

[0027] The water channel G has a vertical water channel extending in the vertical direction and an inverted L-shaped water channel connected to the vertical water channel. Water inlets and outlets g1, g2, and g3 are formed in this water channel G.

[0028] The water channel H has a horizontally extending lateral water channel, a quarter-circle curved section connected to one end of the lateral water channel, a vertical water channel connected to the upper end of the curved section and extending upward, and a vertical water channel extending upward from the lateral water channel. Water inlets and outlets h1, h2, and h3 are formed in this water channel H.

[0029] When a flat plate 3 is superimposed on a plate 2 having multiple water channel grooves A to H and the two are connected and fixed, each water channel groove A to H is covered by the flat plate 3, thereby forming a water channel consisting of water channels A to H. Packing or other sealing members are provided along the edges of each water channel groove A to H.

[0030] Figure 2 shows another example of a channel bed. This channel bed 1' consists of a plate body 2' and a flat plate 3' having channel holes and nozzles 4. Channel grooves I, J, K, and M are provided in the plate body 2'.

[0031] Water channels I have water inlets and outlets i1 to i11, water channels J have water inlets and outlets j1 to j3, water channels K have water inlets and outlets k1 to k8, and water channels M have water inlets and outlets m1 and m2.

[0032] By superimposing a flat plate 3' onto this plate 2' and connecting and fixing the two together, a water channel plate 1' having water channels I, J, K, and M is constructed.

[0033] A membrane separation system can be constructed using these channel plates 1 and 1'. An example of a membrane separation system using channel plates 1 and 1', a machine frame, and a filter housing box is shown in Figure 3.

[0034] The pre-treatment filter and activated carbon filter, described later, are installed inside the filter storage box 5. A machine frame 6 is installed adjacent to the filter storage box 5, with channel bed 1 positioned to the left of the machine frame 6 and channel bed 1' positioned to the right.

[0035] The machine frame 6 has a pair of side plates 7 and 8, and a bottom plate 9c, shelves 9a and 9b, and a top plate 9d that are installed between the side plates 7 and 8.

[0036] Two pumps, P1 and P2, are installed on the base plate 9c. RO modules 21-24 are installed on shelves 9a and 9b.

[0037] Using the water channels A to M and piping, the pre-treatment filter 14, activated carbon filter 16, and RO modules 21 to 24 are connected in a way that allows water to pass through, as shown in Figure 4. As shown in Figure 3, by using the water channel plates 1 and 1', the components of the membrane separation equipment can be efficiently arranged, and the equipment can be made compact and lightweight.

[0038] This channel bed and membrane separation equipment will reduce the number of parts and manufacturing time, prevent errors during replacement, simplify parts replacement, and reduce the effort required for manual piping work.

[0039] Figure 4 is a flow path configuration diagram of the membrane separation equipment shown in Figure 3, and Figure 5 is an explanatory diagram of the flow during RO module water flow operation.

[0040] Raw water is supplied to the first RO module 21 through pipe 11, channel H (inlet / outlet h3→h1), pipe 12, channel F (inlet / outlet f3→f2), pipe 13, pretreatment filter 14, pipe 15, activated carbon filter 16, pipe 17, channel A (inlet / outlet a4→a2), pipe 18, pump P1, and pipe 19. Permeate from the first RO module 21 is removed through pipe 31, channel I (inlet / outlet i11→i7), pipe 45, channel J (inlet / outlet j1→j2), and pipe 46.

[0041] The concentrated water from the first RO module 21 is supplied to the second RO module 22 through piping 41, and the permeate flows from piping 32 into the water channel I (i10→i7) and is similarly extracted.

[0042] The concentrated water from the second RO module 22 is supplied to the third RO module 23 through piping 42, and the permeate flows from piping 33 into the water channel I (i9→i7) and is similarly extracted.

[0043] The concentrated water from the third RO module 23 is supplied to the fourth RO module 24 through piping 43, and its permeate flows from piping 34 into the water channel I (i8→i7) and is similarly extracted.

[0044] The concentrated water from the 4th RO module 24 flows out from the pipe 44 through the inlet / outlet k7 into the channel K. Channels 45, 46, and 52 are formed by channel K. Channels 46 and 52 branch off from channel 45.

[0045] A portion of the concentrated water that flows from pipe 44 into waterway 45 via inlet / outlet k7 flows out of waterway 46 into pipe 47 via inlet / outlet k2 and is extracted as RO concentrated water.

[0046] The remaining concentrated water from channel 45 flows out of channel 52 through inlet / outlet k8 into pipe 53, is sent via pump P1 to pipe 17 and then to the first RO module 21, where it is subjected to RO treatment again.

[0047] Any inlets and outlets or pump P2 not used in the above process are used when using permeate water for backwashing the RO module or filters 14 and 16, or for other purposes, or when injecting chemicals into the flow path.

[0048] The above embodiment is just one example of the present invention, and the present invention may have configurations other than those described above.

[0049] For example, in the above embodiment, four RO modules are used in series, but one, two, three, or five or more RO modules may be used.

[0050] In the above embodiment, multiple RO modules are used in series, but they may also be used in parallel.

[0051] In the above embodiment, an RO module is used, but other modules such as a UF module may be used, or multiple types of membrane modules such as a UF module and an RO module may be used.

[0052] In the above embodiment, a pretreatment filter and an activated carbon filter are used, but only one of the filters may be used, or another filter may be used as well.

[0053] The material of the panels 2,2' is not particularly limited, but examples include PVC (polyvinyl chloride), acrylic, PP (polypropylene), and PE (polyethylene), and should be selected appropriately depending on cost and required water quality. The material of the flat plates 3,3' is preferably the same as the material of panel 2 from the standpoint of adhesion, but is not limited to this. [Explanation of Symbols]
