An apparatus that can be used for producing chlorine dioxide is provided. The apparatus comprises a single fluid proportioning device (20), which comprises three or more fluid transferring devices, a conduit to the inlet (21, 22, 23) of each fluid transferring device, a conduit to the outlet (31, 32, 33) of each fluid transferring device, a water inlet (11) to the device, and a water outlet (12) from the device in which the fluid transferring device is proportionally actuated by the flow of water through the device. Also provided is a process that can be used to produce chlorine dioxide. The process comprises flowing water through the fluid proportioning device to create a downstream water and to actuate the fluid transferring devices; drawing three or more precursor chemicals each from a separate source and flowing each chemical separately through one of the fluid transferring devices; and injecting the precursor chemicals into the downstream water. |
