Claim Text:
1. A water treatment system, comprising: a conduit having an inlet fluidly connectable to a source of water to be treated; a source of sulfuric acid; a source of sodium chlorite; a first in-situ chlorine dioxide reactor having a first reactor volume in fluid communication with the sources of sulfuric acid and sodium chlorite and in fluid communication with the water to be treated at a first point of addition in the conduit; and a second in-situ chlorine dioxide reactor having a second reactor volume in fluid communication with the sources of sulfuric acid and sodium chlorite and in fluid communication with the water to be treated at a second point of addition in the conduit downstream of the first position, the second reactor volume being different than the first reactor volume; and a system controller configured to control introduction of chlorine dioxide to the water to be treated by controlling a first flow rate of the sulfuric acid and a first flow rate of the sodium chlorite to the first generator and a second flow rate of sulfuric acid and a second flow rate of sodium chlorite to the second generator in response to monitoring of a system parameter.
