Unveiling the Science of Polymer Activation: Exploring the Benefits through Applications

Abstract

The optimization of polymer use in water and wastewater treatment processes remains a challenge, leading to high recurring expenses and sub-optimal process performance. This presentation emphasizes the critical role of polymer activation and its direct impact on process efficiency. By selecting suitable polymer and employing appropriate mixing technologies, polymer activation can reduce polymer usage and enhance the downstream separation process, resulting in improved overall performance and substantial annual cost savings. The presentation focuses on the science of polymer activation, offering insights into the fundamental principles of polymer mixing. It showcases the advantages of adopting a two-stage mixing approach, characterized by high initial mixing energy followed by low and uniform mixing energy. Theoretical considerations and practical test data provide tangible evidence of the benefits of this approach for both emulsion and dry polymers. Additionally, a comparative analysis of mechanical and hydraulic mixing technologies will be presented to aid in equipment selection for specific applications. Through a series of compelling case studies, the presentation not only highlights the impact of polymer savings but also demonstrates the effect on the process downstream. Comparisons between different mixing technologies will provide insights for decision-making processes when optimizing polymer activation. Additionally, the discussion will include design considerations and valuable lessons learned, offering practical guidance for implementing effective polymer activation solutions.
