| Abstract: | Due to some problems such as sludge leaking, unstable outflow and excessive pressurization in the running of air weir, an air pressure control was built to control the operation through a dualcontrol system. Four alarms were installed to warn the troubles happened in PLC, air inlet valve, overpressure and siphon. Thus, it is easier for operators to find the problems and get back the running rapidly. The stability and safety of the air weir are improved greatly. |
