| Abstract: | The operating principle of biological aerated filter (BAF) in a refinery wastewater treatment facility was introduced, and the feature and requirement of this facility to automatic control system were simply discussed. SIMATIC S7-300 programmable controller was implemented for automation of this facility. The structure of the control system, the assignment and implementation of tasks, the control scheme and the design concept of program are introduced concretely. Combination of sequential, time limited and condition controls have been applied for the valves, aerators, air blowers and pump assemblies. |
