At this time, the coagulant is added to the raw water, so that the mixed water in which the raw water and the coagulant are mixed is delivered from the mixer 3. Then, the mixed water is stored in the storage tank 8, and when the rotary cylindrical filter 9 immersed in the mixed water is rotated, the mixed water is filtered from the outside to the inside of the filter cylinder. Next, the filtered water filtered by the rotary cylindrical filter 9 is collected from the take-out pipe 9 a and is pressure-fed to the second filter 14 by the operation of the filtration pump 13. At this time, if the purified water amount in the second filter 14 may be reduced due to the low temperature of the filtered water, the cooling water received by the engine cooling is circulated in the hot water pipe 16 so that the inside of the pipe 15 is cooled. The filtered water flowing through is heated.

飲料水として送出される。In the second filter 14, the supplied filtered water is subjected to microfiltration or ultrafiltration, and is pretreated so that the reverse osmosis membrane device 20 provided at the subsequent stage can treat the water to a quality that allows it to be treated. The filtered water from which suspended matter has been removed by the pretreatment is then pressurized by the high-pressure pump 18 and supplied to the reverse osmosis membrane device 20. In the reverse osmosis membrane device 20, pure water is separated from the supplied filtered water, and the pure water thus obtained is then injected with a sterilizing agent and delivered as drinking water.
