In a first aspect, a method of chemical delivery is provided. The method includes the steps of (1) receiving a first input flow of a dilutant; (2) receiving a second input flow of a chemistry; (3) combining the first and the second input flows into a combined flow; (4) employing a mixer to mix the combined flow such that a homogeneity of the combined flow is increased; (5) dividing the combined flow into at least a first output flow and second output flow; (6) directing the first output flow toward a first scrubber dispensing element; and (7) directing the second output flow toward a second scrubber dispensing element. Numerous other aspects are provided.
