A digital twin model based operation and optimization of a reverse osmosis plant uses a data processing system to receive data for a reverse osmosis membrane in a plant that with a plurality of assets. The data processing system can determine a level of performance of the membrane based on the data for the membrane input into a model generated with sa topology indicative of one or more relationships and a flow path between the plurality of assets, predict, based on the model and responsive to the level of performance input into an optimization function for the plant, a time at which the level of performance degrades below a threshold, and provide an indication of the time at which the level of performance degrades below the threshold predicted using the optimization function to cause servicing of the membrane used to process the fluid at the plant.

A management method for a water treatment device that serves as a management method for water treatment equipment provided with a plurality of water treatment devices on each of which a plurality of water treatment members is mounted includes performing life expectancy estimation processing to estimate a life expectancy of each water treatment member based on history information of each water treatment member, the history information being updatable as needed, and performing external life expectancy homogenization processing to replace corresponding water treatment members with each other among a plurality of water treatment devices at a predetermined period so that other water treatment members each having a life expectancy within a predetermined range with respect to the life expectancy of each water treatment member estimated in the life expectancy estimation processing are mounted in an identical water treatment device.

A water treatment system has a water treatment tank that stores a resin bed, a conductivity monitor, a valve assembly, a flow meter, and a controller. The control valve assembly is switchable to selectively permit untreated water flow into the tank, treated water flow out of the tank, and regenerant flow into and out of the tank. In one configuration, the conductivity monitor includes at least an uppermost probe located within 6″ of the nominal mid-point of the resin bed and a second probe located half-way between the first probe and the bottom of the resin bed. Signals from these probes are used in combination with flow data as measured by the flow meter to provide precise information regarding volumetric capacity as depletion is registered at each probe. Also disclosed are an improved technique for sampling data from the conductivity monitor, and a wireless conductivity monitor.

A method of concentrating a process fluid, including a carrier fluid, including: (a) maintaining a process fluid at a predetermined temperature value/range; (b) evaporating the carrier fluid from the process fluid to produce a concentrated process fluid; (c) monitoring at least one process variable of steps (a) or (b) to detect fouling formed in either step (a) or (b); and (d) initiating a cleaning protocol if the process variable deviates from a predetermined value/range to reduce the fouling formed.
