High Centrifugal Force
Tubular centrifuges operate at ultra-high rotational speeds (up to 15,000-50,000 RPM), generating intense centrifugal forces (up to 20,000-60,000 × g). This enables efficient separation of microalgae (typically 1-50 μm) from liquid media.
Gentle Processing
Minimizes cell damage compared to mechanical methods, preserving algae viability for applications requiring live biomass (e.g., biofuels, aquaculture).
Scalability for Small to Medium Volumes
Ideal for lab-scale or pilot-scale processes, though less suited for very large industrial volumes compared to disc-stack or decanter centrifuges.
No Filter Clogging
Avoids issues with filter-based methods (e.g., membrane fouling), especially for viscous or high-solid-content algal suspensions.
Compact Design
Vertical tube configuration requires minimal space, making it suitable for modular or space-constrained setups.
Continuous or Batch Operation
Some models allow semi-continuous operation, enhancing productivity for repetitive separation tasks.
Vertical Tubular Rotor
A long, narrow rotating cylinder maximizes centrifugal force by increasing the sedimentation path length.
Separation Mechanism
Utilizes density differences to separate algae (solid phase) from the liquid phase. Heavier particles migrate outward, while clarified liquid forms an inner layer.
Versatility
Adjustable parameters (speed, feed rate, run time) allow optimization for diverse algae species (e.g., Chlorella, Spirulina) and varying cell sizes.
High Purity Output
Achieves high biomass recovery rates (>90%) and produces a dense algal paste with low moisture content.
Low Energy Consumption (Relative to Output)
Energy-efficient per unit of processed biomass compared to some alternatives, though high RPM requires robust motor systems.
Ease of Cleaning
Simple disassembly for sterilization or maintenance, critical for avoiding cross-contamination in research or pharmaceutical applications.
Limitations
Small batch capacity per cycle; frequent unloading required for large volumes.
Requires skilled operation to balance rotor and optimize parameters.
Harvesting microalgae for biofuel production, nutraceuticals, or wastewater treatment.
Clarifying algal cultures for extraction of pigments (e.g., astaxanthin, chlorophyll) or proteins.
Lab-scale research on algal physiology or biotechnology.
