The present invention relates to a process and a system for the at least partial removal or exchange of solvent from/in a suspension comprising microfibrillated cellulose (MFC)， specifically the at least partial removal of solvent from a suspension comprising microfibrillated cellulose having a comparatively high solvent (water) content to a relatively lower solvent content. Accordingly， the solids content of the microfibrillated cellulose increases during the the step of at least partial removal of solvent from a suspension comprising process， in particular from a first solids content in the range of from 0.1 % weight by weight ("w/w") to 6 % w/w， preferably 1 % weight by weight ("w/w") to 5% w/w， up to a second solids content of above 5 % w/w， preferably to a solids content of from above 5 % w/w - 50% w/w， further preferably to a solids content of from above 5 % w/w - 25% w/w. In a separate aspect， a solvent exchange step after the at least partial removal of a first solvent is also part of the present invention.
