A method for feeding one or more chemicals into a process stream of a papermaking process comprises providing one or more apparatuses comprising a first conduit having one or more inlets 2 and outlets, a second conduit having one or more inlets 5 and outlets, and a mixing chamber 7 that has one or more inlets and outlets. The first conduit secures to and traverses the second conduit. The second conduit is secured to the mixing chamber. The outlets of the first conduit and the outlets of the second conduit are in communication with the mixing chamber 7. An adaptor 8 is mounted over an opening in at least one of the following locations of the papermaking process: the thick stock line, between a refiner and the machine chest outlet, proximate to a basis weight valve, and between a machine chest and basis weight valve. The adaptor 8 is in communication with the outlets of the mixing chamber 7 and is secured to the mixing chamber 7. The papermaking process is run so that the process stream flows through the papermaking process. Chemicals and a feeding liquid are introduced into the mixing chamber 7 by introducing the chemicals and feeding liquid into the inlets of the first conduit and the second conduit. The chemicals and the feeding liquid are then mixed in the mixing chamber 7 to form a mixture of the chemicals and the feeding liquid. The mixture is then dispensed into the process stream through the adaptor 8.
