Project Overview:
Effluent Treatment Plant automation and different parameters monitoring.

Components:
S7 300 PLC, Analog and Digital Inputs and Outputs, TP 700 HMI, SCADA etc.

Process Summary:
The PLC collects reading from Electro Magnetic Flowmeter, Ultrasonic Level Meter, DO Sensor, pH Sensor. The PLC compares the sensor readings with setpoint. When sensor reading is higher than setpoint, the PLC starts the blower pumps sequentially using PID and it turns off the pumps sequentially when DO and pH are close or below the desired level.
