The invention relates to a device for metering and dissolving lime in water courses. The device is driven by water and produces an intermittent flow of water in its dissolution part. As a result, the lime particles can be kept in such a state of movement that they dissolve more rapidly, by means of rubbing against each other and parts of the device, without the water washing undissolved lime particles out of the equipment. <IMAGE> |
