EIMIX stands for Enhanced In-Tank Mixer, a novel approach to digester mixing developed by Baker Process. Unlike traditional mixers that rely on mechanical agitation, EIMIX utilizes a unique combination of air injection and hydraulic principles to achieve optimal mixing within anaerobic digesters.
Traditional Mixing Challenges:
EIMIX Advantages:
How it works:
EIMIX works by injecting air at the bottom of the digester, creating a gentle upward flow that circulates the digester contents. The air bubbles are strategically positioned and controlled to create the optimal mixing pattern, ensuring even distribution of solids and nutrients throughout the digester.
Applications:
EIMIX is applicable for various digester types, including:
Conclusion:
EIMIX offers a revolutionary solution to the challenges of digester mixing, delivering superior performance, reduced operational costs, and enhanced biogas production. By embracing this innovative technology, wastewater treatment facilities can achieve improved efficiency and sustainability in their anaerobic digestion processes.
