SCADA Assisted Control of Biological Treatment Plants: Subaşi Example

Abstract

A disadvantage of collective life is the problem of collective waste. Water is the most important source of life. The fresh water obtained from the nature is contaminated and returned to the nature. In bulk settlements, there is a large amount of waste water. High amounts of waste water can not be cleaned naturally in a rapid manner. For this reason wastewater treatment facilities have been established in settlements. Waste water entering these facilities is cleaned by biological methods and given to nature. The purification is made of bacteria-based. In the treatment process, the number of bacteria and the amount of water entering and leaving the water cleaning are measured and process control is carried out. In this study, control of a wastewater treatment plant located in Edirne Subaşı was done by PLC. Sensors located in the field are processed by PLC and data is transferred to SCADA. The equipment was controlled on the SCADA according to the received data. Level control, oxygen control, flow control, dosing control are some of these controls. All these inspections can be carried out on a single center via SCADA.
