Claim 12:
13. The method as claimed in claim 1 comprising the steps of:
providing the at least one primary vessel as a plurality of primary vessels, wherein each primary vessel comprises a vessel body, a gravitationally-higher side, a gravitationally-lower side, and a product valved outlet, and wherein the gravitationally-higher side and the gravitationally-lower side are positioned opposite to each other about the vessel body, and wherein the product valved outlet is positioned proximal to the gravitationally-lower side and is positioned distal to the gravitationally-higher side, and wherein each adjacent pair from the plurality of primary vessels comprises a gravitationally-higher primary vessel and a gravitationally-lower primary vessel, and wherein the product valved outlet of the gravitationally-higher primary vessel is in fluid communication with the gravitationally-higher side of the gravitationally-lower primary vessel;
executing a plurality of iterations for steps (C) through (I), wherein each iteration for steps (C) through (I) uses a different primary vessel from the plurality of primary vessels;
draining the quantity of purified water out of the gravitationally-higher primary vessel and through the product valved outlet of the gravitationally-higher primary vessel during step (I) of an arbitrary iteration, wherein the arbitrary iteration is any iteration from the plurality of iterations for steps (C) through (I); and
receiving the quantity of purified water for the arbitrary iteration as the quantity of source water for a subsequent iteration into the gravitationally-lower primary vessel before step (C) of the subsequent iteration, wherein the arbitrary iteration and the subsequent iteration are two consecutive iterations from the plurality of iterations for steps (C) through (I).
