<p>An apparatus for providing a predetermined volume of biocidally treated water to a feed water side (110) of a reverse osmosis device (108) when it is shut down. A biocide dispenser (144) treats a predetermined volume of water from a source with a biocidal agent. A valve (146), coupled to the source of the predetermined volume of water, transfers the predetermined volume of water to the feed water side of the reverse osmosis device (108). A controller, coupled to the valve (146), causes the transfer of the predetermined volume of water after a source of feed water connected to the feed water side (110) of the reverse osmosis device (108) is shut off, and then causes the predetermined volume of water to remain in the feed water side (110) of the reverse osmosis device (108) while the reverse osmosis device (108) is shut down.</p> |
