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 desalinating water, including the steps of when electricity costs between a first predetermined price and a second predetermined price, fill water is pumped into a reverse osmosis desalination unit to yield desalinated permeate and saltwater having a first salinity, when electricity costs less than the first predetermined price, fill water is pumped into a reverse osmosis desalination unit to yield desalinated permeate and saltwater having a second salinity, and when electricity costs greater than the second predetermined price, pure water is flowed into a reverse osmosis unit to yield pressurized saltwater which is run through a turbine to generate electricity. The first salinity is lower than the second salinity.

A control method for an RO system, which is a control method for an RO system that includes a plurality of RO devices 41 to 44 arranged in parallel, a control unit that controls a start/stop process including an operation process and a stop process of the RO devices 41 to 44, and a chemical injection unit that injects a chemical that mitigates fouling during the stop process. The control method performs control such that a number of times of start/stop increases for RO devices that are more likely to recover treatability through start/stop operations, and a stop-time is controlled according to a recovery rate.

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.

An electrodialysis system controller is configured to be coupled to a power supply, and powered devices that include a pump, and an electrodialysis unit. The controller receives inputs including an input indicative of a flow rate through the electrodialysis unit, an input indicative of a concentration level of fluid in the electrodialysis unit, and an input indicative of a power differential (e.g., indicating a degree to which a power usage by the powered devices differs from available power of the power source), and provides outputs for controlling the powered devices, including an output for causing a variable current level to be applied in the electrodialysis unit, and an output for causing a variable fluid flow rate through the electrodialysis unit. The controller is configured to match the power usage to the available power, for example, to keep the power differential as small as possible, while maximizing the theoretical desalination rate of the electrodialysis system.
