We are pleased to announce the completion of the startup and commissioning of a new high-performance Dissolved Air Flotator. Designed to operate at a nominal flow rate of 600 m³/h, the equipment is already in full operation, optimizing wastewater treatment and resource recovery at yet another pulp and paper plant in Brazil.
The Challenge of Field Commissioning
The startup of a Dissolved Air Flotation (DAF) system requires a rigorous technical protocol. During commissioning, our engineering team focused on stabilizing the system hydrodynamics, ensuring that solid-liquid separation took place at maximum efficiency from the very first hours of load.
Saturation Synchronization: Fine-tuning of the multiphase pumps to ensure air dissolution in the liquid phase, generating the microbubble "cloud" needed for the solids to rise.
Velocity Gradient Calibration: Parameterization of the mixers and the flocculation chamber to form resistant flocs, avoiding shear before entering the flotation zone.
Chemical Optimization: Adjustment of the flocculation gradients to minimize polymer and coagulant consumption, keeping the sludge blanket stable even under flow variations.
Immediate Results on the Process Line
After reaching steady-state operation, the Flotator delivered results that exceeded the initial design expectations. The clarity of the recovered water (white water) and the consistency of the floated fiber sludge were the main highlights:
Clarification Efficiency: Drastic reduction in turbidity, allowing immediate reuse of the water in cleaning showers and other critical points of the paper machine.
Solids Recovery: High fiber removal rate, directly reducing raw material waste.
Operational Stability: The system showed high resilience to load and flow variations.
Technical Expertise at the Service of Industry
More than the delivery of a piece of equipment, the startup of the Flotator 600 involved intensive training of the customer's operation and maintenance teams. We focused on transferring knowledge about sludge blanket control and the optimization of polymer consumption, ensuring that high performance is sustainable in the long term.
Innovation and Performance in Solid-Liquid Separation
Our engineering remains committed to delivering solutions that combine mechanical robustness and process intelligence. This Flotator is the ultimate example of how flotation technology can turn an environmental liability into a productivity gain for the pulp and paper sector.
