Desenvolvimento e avaliação do desempenho de flotador alternativo para tratamento de agua residuaria sintetica da industria de alimentos
TL;DRAbstract
The objective of this work was to develop and evaluate the performance of a flotator with a porous stone inserted in the modified Venturi throat for bubbles air formation, used to float suspended particles of milk after settlement of the pH to approximately 4.6, in which occurs the milk proteins isoeletric point implying in the proteins precipitation. The use of the Venturi excuses the use of steam and pressure reduction valves for bubbles air formation, essential in the flotation. It was carried out experiments in batch and continuous system for different flotation times, different wastewater recycle flow rates (Q L ) and air flow rates (Q ar ). The system efficiency was evaluated through the determination of the suspended solids concentration of the flocculated milk in the affluent and effluent of the equipment.
