Multiple-cylinder biofilm reactor for predicting microbial corrosion
An innovative biofilm reactor enabling precise control of conditions to study and predict microbiologically influenced corrosion (MIC) across different materials and environments. It provides a flexible platform for testing, with modular configuration and precise hydrodynamic control.
Overview
The multiple-cylinder biofilm reactor (MCBR) is a cutting-edge platform designed to study microbiologically influenced corrosion (MIC). By enabling the simulation of various environmental conditions, the MCBR allows for the examination of biofilm formation on different materials, which is crucial in predicting and mitigating MIC. This reactor provides an invaluable tool for industries where corrosion poses a significant risk, offering flexibility in material selection and environmental settings to accurately replicate real-world scenarios.
Technical specifications
Key features:
- Modular Structure: Comprises four independent vessels for simultaneous testing of distinct conditions.
- Hydrodynamic Precision: Adjustable rotation speeds of synchronized shafts allow precise control over fluid dynamics.
- Versatility: Supports both continuous and batch operation modes with customizable nutrient and salt compositions.
- Comprehensive Testing: Capable of testing different materials under uniform or varied conditions such as aerobic/anaerobic environments, temperature, salinity, and pH.
- Advanced Analysis: Utilizes scanning electron microscopy, electrochemical impedance spectroscopy, and linear polarization resistance to evaluate biofilm and corrosion metrics.
Technology readiness level
The MCBR is at technology readiness level 6, indicating that it has been demonstrated in relevant environments. It is ready for further validation with specific bacterial strains and environmental conditions tailored to industry requirements. This stage supports its use in experimental setups to advance understanding and mitigation of MIC in diverse applications.
