A method and apparatus for supplying dry detergent concentrate to a metering device for dissolving or dispersing in water which prevents or minimizes the formation of dust, lumping, caking, and encrustation of vessel walls and supplies new detergent to the laundry plant in response to changes in electrical conductivity of the wash water from a predetermined value which indicates consumption of original detergent required in soil removal and need for replenishment thereof. The minimizing of dust and protection of the detergent from moisture is accomplished by using a flexible delivery container, the filling means and emptying means of which are sealable and which emptying means acts in cooperation with the metering apparatus section to form an integral delivery system which is generally isolated from the surrounding atmosphere.
