AI Technical Summary
Existing microalgae culture systems face high costs due to high power consumption, low algal cell density, and inefficient light utilization, leading to slow growth and high harvesting costs, while also being susceptible to contamination.
A method and device for adherent culture of microalgae in a thin liquid layer using mobile mechanical stirring, which includes a subsystem for adherent culture with a mechanical stirring assembly and a moving assembly to suspend and settle microalgae, maintaining a thin liquid layer of 1-5 cm depth, and utilizing rotating or fixed blades for stirring, with a control assembly to optimize conditions.
This approach reduces power consumption by 80-95%, lowers device costs by 10-20%, increases algal cell density and growth rate, enhances light utilization, and minimizes contamination, resulting in high-quality, high-density microalgae production with reduced harvesting costs.
