Abstract: PROBLEM TO BE SOLVED: To rapidly feed drinking water in case of emergency, etc., by providing a truck with a pump or pumping up a raw water, a device for adding chlorine for disinfection of the raw water, a cleaning device and an ultraviolet rays irradiating device for sterilization of clean water. SOLUTION: On a movable truck, a pump 1 for pumping up a raw water such as water for fire fighting and water in a pool and a cleaning device 3 are arranged and a chlorine adding device 2 is disposed on the midway of a pipeline between the pump 1 for pumping up and the cleaning device 3. The cleaning device 3 is a cleaner consisting of three kinds of filter media and as the first layer, the second layer and the third layer, an ion exchanging body 6, an active carbon 7 and a hollow fiber membrane module 8 are respectively used. A low pressure mercury lamp is inserted into an outlet 9 of the treated water of the cleaning device 3 as an ultraviolet rays irradiating device 4 and the treated water discharged from this ultraviolet rays irradiating device 4 is used as a drinking water from a water supply tap. In addition, in this case, under a condition where a clean water tap is closed, a safety valve 5 is worked and the pumped-up raw water is returned to a raw water tank.

Abstract: PROBLEM TO BE SOLVED: To purify a pool water without a high-level purifying means and a new burden of a water charge by providing the water purifying means purifying a part of a pumped up pool water and returning to a pool, a chore water supply means supplying a residual pool water as the chore water and a new water supply means supplying the new water to the pool. SOLUTION: The water overflowed from the pool 1 by movement, etc., of people is received with an overflow ditch 2 and made to flow to a raw water tank 5, and also a part of the water pumped up from a bottom part of the pool 1 in accordance with a water level of a chore water supply tank 13 is sent to the raw water tank 5. At the raw water tank 5, a pump 6 and an urgent shielding valve 19 are controlled so that the water level may be kept within a fixed range based on an output of the water level detecting implement 21. The pool water is sterilized so that its chlorine concn. may be kept in a specified concn. at a chlorine supply device 29, and the sterilized water is filtered with a rotating drum type filter and returned to the pool. The water level of the pool lowered by supplying the purified water and the chore water is controlled by supplying the new water by a new water supply means 32.

Abstract: PROBLEM TO BE SOLVED: To expose the tip opening of a communicating tube thereby functioning it as a siphon breaker by once raising a water supply pipe to a U-shape and connecting the top of the riser piping to a set water depth below the water surface in the water tank when a trouble has occurred. SOLUTION: Water to be purified flows from a water tank 1 to a raw water tank 5 through a water supply pipe 2. Water to be purified which came to the raw water tank 5 is sent to a filter 9 by a water supply pump 10, and filtered water flows to a treated water tank 11 and then returned to the water tank 1 through a treated water piping 13. In a case where the treated water does not return to a water tank 1 due to a trouble, the water level in the water tank 1 drops and a tip opening of a communicating tube 4 connected to the top of riser piping of the water supply pipe 2 is exposed above the water surface and air enters from the opening thereby functioning as a siphon breaker so that the outflow of the purified water from the water tank 1 is stopped. The amount of water to be purified which discharged until the functioning of the siphon breaker can be adjusted by adequately positioning the tip opening of the communicating tube 4 to a certain depth from the water surface in the water tank 1.

Abstract: PROBLEM TO BE SOLVED: To clean the water to be used in cleaning the food, tableware, etc., in the kitchen or used in the livestock and fresh vegetables to prevent the infection due to water by using a hollow-fiber membrane filter as the first filter in the untreated water flow direction and attaching a backwashing mechanism to the filter. SOLUTION: A first filter 1 and a second filter 3 are connected in series with a solenoid valve 2 in between. A branch pipe 9 is connected to the inlet of the first filter 1 through a solenoid valve 8 as a mechanism for backwashing the membrane, and a backwashing pump 5 and a backwashing tank 4 are joined to the outlet in parallel with the solenoid valve 2 through a check valve 6. Further, a check valve 7 is connected to the inlet of the filter 1 on the upstream side of the brach pipe 9 in the raw water flow direction. The untreated water from a city water pipe, etc., is passed through the check valve 7 and filled in the first filter 1. The filtered water is partly stored in the backwashing tank 4 through the solenoid valve 2, and the remainder is sent to the second filter 3, filtered for the second time and discharged as cleaned water.
