Wastewater leaving the ACME cheese factory must be neutralized to a pH between 6.8 and 7.2. Citric acid is available to decrease pH and sodium hydroxide is used to increase pH. The neutralization occurs on-line in the discharge piping by addition of acid or base as required based on upstream pH measurement. draw an appropriate control scheme using the simplified ISA symbols.
