In today's semiautomated water‐treatment plants, chemical feed is based primarily on one variable‐flow rate. This method, according to the author, usually proves inaccurate and wasteful of expensive chemicals. The more desirable solution to this problem is complete automation of the dose rate based upon accurate information provided by on‐line sensors that measure varying chemical constituents of water. In this article, the author describes a computer‐controlled system developed for such a facility.
