Primary Treatment Plant - Swine Processing Plant
About the caseThis project concerns a Primary Treatment Plant to meet the treatment demands of a pig slaughterhouse. One of the main objectives of the project was to reduce parameters before sending waste to biological treatment, and especially to separate solids through W-DAF physicochemical flotation, separating floated sludge with a solids concentration above 8%, which is then sent to a biodigester. The entire process is automatically supervised and controlled, from equalization to the flotation unit outlet, with automatic turbidity control and chemical dosing.
The applied technology successfully met all objectives, and the plant operates with the lowest possible OPEX.

Challenges
- Ensure efficiency in physical-chemical removal with the W-DAF Flotation System.
- Proper homogenization of the effluent in the equalization tank with MIXTARGET AxF, avoiding abrupt load variations.
- Precise control of chemical and polymer dosage to optimize flotation.
- Integration of hydraulic interconnections with system equipment.
- Complete automation via CCM (Motor Control Center) with automation to ensure continuous and reliable operation.
- Operational adjustments in response to variations in flow rate and effluent characteristics.
Results
- High efficiency in removing suspended solids, oils and greases.
- Significant reduction of organic load in the initial stages of treatment.
- Optimized performance of the W-DAF Flotation System with precise chemical dosing.
- Efficient effluent homogenization with MIXTARGET AxF, ensuring stability in subsequent stages.
- Reducing the consumption of chemical inputs through automated control.
Continuous and reliable operation with automation via MCC (Motor Control Center) with automation.
- Improved overall performance of the wastewater treatment plant in terms of flow.
Greater operational predictability and compliance with environmental standards.
