摘要： A system and method for predictive analysis of Seawater Reverse Osmosis (SWRO) desalination plants receives first data associated with a SWRO plant, including a first set of parameters associated with seawater, a second set of parameters associated with a permeate, and a third set of parameters associated with a brine. The system determines a fourth set of parameters by applying normalization techniques to the received first data. The system determines, based upon the fourth set of parameters, a set of membrane performance parameters associated with the SWRO plant, or a set of diagnostic indicators associated with at least one of the SWRO plant and the seawater. The system outputs the determined set of membrane performance parameters or the set of diagnostic indicators.

摘要： The invention relates to a method and a system for controlling a membrane separation unit of an aqueous liquid effluent treatment plant comprising a system for injecting at least one chemical compound into the effluent to be treated. The method and the system allow regulating at least one parameter selected from an amount of chemical compound(s) to be added and a conversion rate in order to avoid clogging and/or precipitation of ionic species in the retentate. This regulation uses optimum setpoint values determined according to one or more parameter(s) characteristic of the retentate and not of the water to be treated. Thus, an accurate regulation of the amount of chemical compound(s) to be added and/or of the conversion rate of the membrane separation unit at an optimum value allowing at the same time avoiding clogging and/or precipitation of the species likely to precipitate and minimising the operating costs is achieved.

摘要： Systems and methods for configuring compact desalination RO systems operable for point-of-use applications are disclosed herein. The compact RO system can include a single RO element disposed in a vessel and connected to one or more pumps in a circulation loop that recirculates fluid through the vessel. The compact RO system can reconfigure, combine and/or eliminate one or more components to reduce a footprint of the system. For example, the RO system can utilize pumps having flow valves integrated therein instead of separate pump and valve components. High recovery ratios can be maintained by allowing brine produced by the RO element to exit the system before passing through the pump. In some embodiments, the system can utilize pulse width modulation (PWM) to change a flow rate of the pump within the system to ensure operation at peak pressure and flow rate.

摘要： A method for controlling a hollow fiber nanofiltration membrane system with controllable power consumption, including the following steps. A filtration flow rate is determined by the program control system according to preset working conditions and the electricity price and the inlet water temperature obtained by a first monitoring module when the hollow fiber nanofiltration membrane assembly is started to perform a filtration process. The inlet water pressure change and the permeability change are monitored and recorded by a second monitoring module during the filtration process. A flushing mode and a flushing intensity of the cleaning system are determined by the program control system according to the inlet water pressure change and the permeability change during the filtration when the filtration process is completed.
