Abstract: A fluid treatment system is provided, comprising a capacitive deionization (CapDI) system for removing dissolved solids from a fluid. A controller is arranged in a closed feedback loop with the CapDI system to verify whether measured conductivity of the fluid corresponds to a set point conductivity value, and if the measured conductivity of the fluid does not correspond to the set point conductivity value, adjust the operation of the CapDI system to match the set point conductivity value. A pump selectively pressurizes the fluid such that purified fluid is at a pressure greater than line pressure of the fluid treatment system. An accumulator provided downstream of the CapDI system maintains the purified fluid at a pressure greater than the line pressure and intermittently delivers purified fluid to a use device. The purified fluid stored in the accumulator comprising chlorine and or chloramine so as to reduce microbial growth when stored in the accumulator.
