Nature of the Work
The Pasakoy plant, which is the city’s biggest biological plant, in its last phase, will be purifying the wastewater refusal of a population of 1.065.000 with a flow rate of 500.000 m³/day. In this phase, the plant has been constructed to treat the wastewater refusal of 250.000 inhabitants. The advanced Biological Wastewater Purification process is intended to remove carbon and nutrients such as nitrogen and phosphorus from the waste, which are the main causes of the pollution of water sources.
The complete plant is controlled by 756 input/output control signals, and is structured around six PLC sections. For the control signals to communicate between the boosting station and the water treatment plant, a wireless modem communication has been established. The entire biological treatment process can be monitored from the control room and can be controlled accordingly. The system provides daily and weekly reports and all the information concerning defect cases and historical data. Meanwhile, this data is saved to the front-end computers’ memories.
