A filter unit for a mixing apparatus includes a hydrophilic filter and a hydrophobic vent filter. The hydrophilic filter is configured to receive a fluid including a liquid and gas. The hydrophilic filter is further configured to sterilize the liquid. The hydrophobic vent filter is configured to receive the gas from the hydrophilic filter. The hydrophobic vent filter further includes a vent and a membrane configured to separate an interior of the filter unit from an exterior of the filter unit, the gas being vented from the filter unit by flowing across the membrane and out of the vent. In some embodiments, the filter unit further includes a defoaming device configured to receive gas, foam comprised the liquid containing trapped gas, and some of the liquid from the hydrophilic filter and is further configured to release at least some of the gas from the foam.

This disclosure relates generally to method and system to monitor and control continuous ultrafiltration (UF) process units. In real time, continuous operation of UF to handle variating concentration in feed stream is tedious and complex. The UF plant system receives a plurality of input data configured to UF process units and from the real time data outliers are removed and missing values are imputed. The prediction module predicts a volumetric concentration factor (VCF) value and a throughput value by selecting a model from a model repository. The optimization module optimizes the VCF value, and the throughput value based on a plurality of optimal variables recommended for a given feed concentration. The UF plant system controls the VCF value and the throughput value for a predefined period of a prediction horizon based on a plurality of trajectory profiles recommended for the feed flow rate, the pressure data, and a feed concentration.

A method of preparing a bioprocess solution includes producing a mixture of liquid and air by hydrating a powder separating the liquid from the air by providing the mixture to a first filter capsule and allowing the liquid to flow to an outlet across a hydrophilic membrane of the first filter capsule while directing the air upwards along the first filter capsule toward a second filter capsule arranged above the first filter capsule, and venting the air from the second filter capsule by allowing the air to flow through a hydrophobic membrane of the second filter capsule.

A blood filtration system may include one or more sensors. The sensors may determine physiological parameters, for instance one or more of venous oxygen saturation (Sv02) or hematocrit of a patient. The blood filtration system may include a controller. The controller may communicate with the one or more sensors. The controller may monitor the physiological parameters using the sensors. The controller may include a display module that generates content. A display may present the content. The content may include a diagnostic matrix having a diagnostic point. The display module may change the diagnostic point within the diagnostic matrix according to changes in the monitored physiological parameters.

A system for desalinating water using membrane distillation (MD) integrated with an ejector includes an ejector module and a membrane module. The ejector module includes a water ejector, a first water circulation pump, and a freshwater tank. Freshwater is continuously pumped from the freshwater tank, through the water ejector, and back to the freshwater tank. The membrane module includes a feed tank, a second water circulation pump, a water heater, and a membrane distillation unit. Salt water from the feed tank is pumped through the water heater to form vapor, which is then directed to the membrane distillation unit. The membrane distillation unit comprises a feed chamber, a membrane, and a vapor chamber. Vapor passes through the membrane to the vapor chamber, which has an air inlet for pressure differential and is connected to the water ejector. Desalinated water is collected in the freshwater tank.
