Abstract: The invention relates to a modular flow system having a plurality of frame elements (101, 102) configured to be combined together to form a stack for forming a functional member. This functional member may be in particular a membrane distillation stage, a vapor generator, a condenser, a heat exchanger, a filter and/or a pervaporation stage. The frame elements (101, 102) each include: ⋅ an outer frame (39) and an inner frame (43), the inner frame (43) encasing a central inner region (40) and being surrounded by the outer frame (39), and ⋅ passage openings (13 to 16) and vapor and/or liquid channels (17, 18) arranged between the outer frame (39) and the inner frame (43). At least one of the two vapor and/or liquid channels (17, 18) is connected to the central inner region (40) by at least one vapor and/or liquid channel opening (22) constituting a through hole in the inner frame. In the frame elements (101, 102), when combined together to form the modular flow system, the vapor and/or liquid channels (17, 18) are arranged above the inner region (40).

Abstract: The invention relates to a multistage membrane distillation apparatus (5000), comprising a plurality of multistage membrane distillation modules (500, 600), the modules being configured to be flowed through in parallel by a liquid (F) to be concentrated. Each module comprises a plurality of serial condensation/evaporation stages (50, 60) configured to be flowed through in series by the liquid to be concentrated. Each condensation/evaporation stage comprises a plurality of parallel condensation/evaporation elements (101, 102) configured to be flowed through in parallel by the liquid to be concentrated. Each condensation/evaporation element comprises at least one condensation unit and at least one evaporation unit. The apparatus further comprises at least one of: a centralized heating stage configured to generate steam and to provide the steam to each of the modules in parallel, and a centralized condensation stage configured to receive steam from each of the modules in parallel and to condensate the steam.
