[0015] As shown in FIG.
It is composed of a cylindrical cartridge 13 using a hollow fiber membrane 14 as a filter medium and a connector. Four cartridges are arranged in parallel in two rows, and the upper and lower portions of the cartridge are connected by connectors. With two hollow fiber membrane filters, the number of cartridges is 16, and the effective filtration membrane area is 20 m 2 . In the present invention, if the above-mentioned fresh water generator is installed on a portable platform, it can be easily moved in an emergency to produce fresh water. Raw water is supplied to the purification means 2. At this time, since the check valve 15 is provided, it is not necessary to switch the flow path using a valve or the like, regardless of which pump is used, and it is possible to prevent the raw water from flowing back to the unused flow path. Raw water supplied to the purification means 2 is removed with a thread filter 4 to remove coarse suspended matters, and then an activated carbon tank 5 is used to adsorb and remove harmful substances. Then, the hollow fiber membrane filter 6 removes bacteria and particulate components in the treated water. The treated water obtained by filtration by the purification means 2 is supplied as purified water after disinfecting by injecting chlorine in the chlorine addition device 3.

Here, when the hollow fiber membrane is contaminated, upstream of each of the two hollow fiber membrane filters 6 is disposed so that the treated water from the activated carbon tank flows into only one of the hollow fiber membrane filters 6. Set so that the discharge pipe of the connected one-way valve 9 is closed,
The other three-way valve 9 is set so that the upstream side is closed.
The two-way valve 10 provided on the downstream side of the hollow fiber membrane filter 6 is closed. By doing so, the filtered water of one hollow fiber membrane filter 6 can be used as the backwash water of the other hollow fiber membrane filter 6.
Since the three-way valve 9 provided on the upstream side of the other hollow fiber membrane filter 6 is open to the discharge pipe, the water used for the backwash can be discharged out of the system therefrom.

With such a fresh water generator, when pool water is used as raw water, 400 m 3 or more of fresh water can be continuously produced without replacing the filter medium. At the time of training or the like, since the time is short and the amount of fresh water is small, an impermeable dummy may be used if necessary to reduce the actual number of filters and the amount of activated carbon. In that case, there is no problem with the quality of the purified water. In addition, even if the number of hollow fiber membrane cartridges that require particularly high replacement costs and take a long time to dry
Since the engine pump 7 having a wide flow rate range of 00 liter / minute is mounted, fresh water generation of 30 liter / minute can be performed without any trouble.
