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: This disclosure relates to a multistage distillation system for concentrating a feed liquid, the system including at least one module being assembled by a stack of frame elements, wherein each module includes at least one stage, such that the system includes in total a plurality of stages configured to be flowed through in series by a main feed liquid. Each stage of the plurality of stages is configured to generate steam and feed the steam to a subsequent stage. The first stage of the plurality of stages is configured to heat the main feed liquid and/or to be fed with heated main feed liquid. The system further includes an intermediate cooling device configured to cool the heated main feed liquid before flowing to at least one of the second to last stages of the plurality of serial stages.

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.
