Control of water treatment chemistry utilizing instrument measurement of system water flow and cycles of concentration provides precise control of chemical additives. The chemical testing performed then becomes a check on the control, rather than a primary control output. On-line chemical analysis is not needed. Statistical analysis of data proves the control capability is excellent. Opportunities exist to utilize existing instrumentation in some cases along with new measurements to synthesize systems that are effective, economical and fully connected with today's information technology.
