Abstract: A system for washing processed biomass and removing dissolved solids from the biomass including: a pre-hydrolysis reactor vessel having an outlet to discharge a biomass slurry, wherein the pre-hydrolysis reactor vessel is operated at conditions that promote hydrolysis of the biomass; a retention tank receiving the biomass slurry discharged through the outlet of the pre-hydrolysis reactor vessel, wherein the retention tank receives recovered wash liquid and is configured to dilute the biomass slurry in the tank with the recovered wash liquid and discharge diluted biomass slurry, and a drain device including a biomass slurry inlet receiving the discharged diluted biomass slurry from the retention tank, a solids outlet to discharge concentrated biomass slurry, and a liquid drain to discharge liquid extracted from the discharged diluted biomass slurry, wherein the liquid drain is in fluid communication with the retention tank such that the discharged liquid flows to the retention tank.
