Biological Treatment Plant - Poultry Fridge
About the caseThis project concerns a Biological Wastewater Treatment Plant using Activated Sludge after the Primary Treatment stage to meet the treatment demands of a Poultry Processing Plant. One of the main objectives of the project was to achieve discharge parameters such as COD, BOD, Nitrogen, and Phosphorus. The embedded automation modulates the Aeration System through readings from the DO sensor, while pH correction is performed automatically by reading the pH sensor and acting on the dosing pumps. In addition, through the reading of Redox Potential, it is possible to control the amount of biomass in the system for nitrate removal.
The applied technology successfully met all objectives, and the plant operates with the lowest possible OPEX.
