| Abstract |
This research was conducted to determine the feasibility of using TOC, ATP and respiration rates as tools for controlling a complete mix activated sludge plant handling a significant amount of industrial waste. Control methodology was centered on using F/M ratio which was determined by the TOC of the influent to the aerator and the TOC (or ATP) of the return sludge. Process control was affected manually and based on 5 to 7 determinations per day. Respiration rates were used to indicate the need for increased or decreased sludge aeration time. Process control decision making was aided by the use of a programmable calculator. Process control information was set up so that operators could input plant data and receive printed instructions for process setting. Functional programs included return rates, mode changes, wasting rates, respiration rate and corrected settlometer volume. |
