Highly configurable adaptable mobile deionization trailer

A method of treating water, comprising:

• providing a water treatment system comprising:
• a water distribution manifold connected to a system inlet and system outlet and including a plurality of valves structured and arranged to provide a configurable flow path along the water distribution manifold, the water distribution manifold including a first branch and a second branch, the first branch and the second branch each in direct fluid communication with both the system inlet and the system outlet;
• and
• a plurality of water treatment vessels each having an inlet and an outlet connected to the water distribution manifold and fluidly coupled between the first branch and the second branch, the water distribution manifold providing for a uniform pressure drop across the plurality of water treatment vessels, the plurality of valves selectively operable to provide for sections of the water distribution manifold to switch between flowing water into one or more of the plurality of water treatment vessels or receiving water from the one or more of the plurality of water treatment vessels;
• and
• measuring one or more water quality parameters from water from a source of water to be treated that is directed to the system inlet;
• configuring a flow path of the water to be treated responsive to the one or more water quality parameters of the water to be treated;
• treating the water to be treated using the plurality of water treatment vessels;
• and
• discharging a treated water from the system outlet.
