System and method for reducing wash water in filtered magma and reducing moisture of filter cake

The invention relates to a system and a method for reducing wash water in filtered magma and reducing moisture of a filter cake. The present invention relates to a system for reducing wash water used in filtering magma comprising sodium bicarbonate and for reducing the moisture of a filter cake obtained as a result of a filtration process in a sodium carbonate production plant applying the Solvar process, the subject system comprises means which can also be added to the present system: at least one filter (1) in which the magma from the carbonation column is dried, at least one mixing tank (2) arranged to wash the filter cake from the filter (1) and to reduce the moisture content of the filter cake to a specific level, the invention relates to a washing machine (1) comprising a mixing tank (2) and arranged to obtain a homogeneous mixture of washing water-filter cake by means of a mixer, at least one centrifuge (3) capable of separating the homogeneous mixture from the mixing tank into a filter cake and a filt
