Biological Treatment Plant - Swine Fridge
About the caseThis project concerns a Biological Wastewater Treatment Plant using Activated Sludge after the Primary Treatment stage, designed to meet the treatment demands of one of the largest pig slaughterhouses in Latin America. 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. Furthermore, through Redox Potential readings, it is possible to control the amount of biomass in the system for nitrate removal, as well as perform Nitrification/Denitrification in the Aerated Reactor where the OXYTARGET Flex Aeration System is installed, due to its flexibility in operating its Mixing and Aeration functions independently.
The applied technology successfully met all objectives, and the plant operates with the lowest possible OPEX.

Challenges
Integration of aeration technologies — OXYTARGET Flex and OXYTARGET Membrane — to maximize efficiency and reduce energy consumption.
- To ensure ideal conditions for aerobic and anoxic processes using MIXTARGET AxF in different stages.
- Precise control of chemical dosage according to load variations.
- Efficient homogenization in the equalization pond to avoid load shocks in the biological system.
- Full integration with automation via MCC with automation and electrical interconnections.
- To ensure operational stability and continuous performance of the biological process.
Results
- High efficiency in biological treatment, with consistent removal of organic load.
- Optimizing energy consumption through the combined use of OXYTARGET Flex and OXYTARGET Membrane.
- Excellent homogenization and process control with MIXTARGET AxF in the equalization and anoxic stages.
Greater operational stability in the face of typical variations in the refrigeration process.
- More efficient chemical dosing, reducing consumption of inputs.
- Complete automation, providing greater control, traceability, and reliability.
- Reduction of operational failures and increased equipment lifespan.
Meeting environmental standards safely and predictably.
