Abstract

PURPOSE:To allow the constitution of a water cleaning device having a water cleaning function of a building unit scale to a relatively small size by dividing a feed water path after a water receiving tank using city water as a water source to the feed water path for drinking and the feed water path for others and passing only the water to be used for drinking through the water cleaning device. CONSTITUTION:Of the water stored in a water receiving tank 4, only the water to be used for drinking is first filtered by a prefilter 6 in the water cleaning device 5, by which the materials included in the water in a water work pipe and the water receiving tank 4 are removed. Further, the water is passed through a mineral adding tank 7 and is sent to an active carbon adsorbing device 8 where the residual chlorine and org. matter in the water are adsorbed. The water is further filtered by a UF membrane 9 by which general bacteria and pathogenic bacteria are removed. The adequate maintenance of the residual chlorine, etc., is then executed by a chlorine adding device 10 and a specified volume of the water is kept stored therein. The circulating path to feed the water directly therefrom to a feed water piping 2 by a feed water pump 11 and to return the water again to the chlorine adding device 10 through a faucet 3 provided in a building is constituted to suppress the generation of microorganisms and general bacteria in the feed water route. A heat exchanger 12 is provided as well to maintain the water at a low temp., to suppress the generation of the microorganisms and to maintain the taste of the water.

(Function) The water stored in the water tank that is used for drinking is first filtered through the pre-filter, removing contaminants from the water pipes and water tank, and then adding minerals to the activated carbon adsorption device. After water is conveyed and residual chlorine and organic matter in the water are adsorbed by an activated carbon adsorption device, the water that has passed through this activated carbon adsorption device is treated with UF.
It is further filtered through a membrane to remove harmful bacteria and pathogens, and then the Seishin equipment is used to properly retain residual chlorine and other substances. Since this water is returned to the disinfection tank equipment through the faucet-side water supply pipe using a water supply pump, the generation of microorganisms and miscellaneous substances in the water supply route is suppressed. The heat exchanger in the disinfection tank equipment keeps the water supply temperature low.
By suppressing the sales of fine products, we are preserving the taste of water.
