Abstract

The present invention relates to a method and apparatus for feeding chemicals into a process liquid flow. The object of a preferred embodiment of the method and the apparatus of the present invention is feeding retention /chemical together with an additive, which may be another chemical or for example a mineral, to paper suspension flow to be fed to a paper machine. The method and the apparatus of the invention are particularly well applicable in feeding an additive of the paper manufacture, such as a filler, together with a retention chemical to paper pulp essentially simultaneously.
