A method of managing ionization for biofouling control in a water intake system that includes channeling a supply water stream through an electrochemical cell, monitoring at least one parameter of the supply water stream, determining an ion concentration threshold for the supply water stream based on the at least one parameter, and controlling the electrochemical cell such that ions are discharged into the supply water stream. The electrochemical cell is controlled such that an ion concentration of a treated water stream discharged from the electrochemical cell is greater than the ion concentration threshold.

A multiple-bore solute cartridge carrier 10) for use in a sterile fluid delivery system. The carrier includes a rotary housing (12) adapted for connection to the sterile fluid delivery system.
