Problems solved by technology

[0005] There are many technical difficulties in the research and development of microalgae, among which there is a lack of efficient, energy-saving, and technologically mature photobioreactors as the research basis, which greatly limits the research and development of microalgae and large-scale development
This is mainly due to the fact that the design of microalgae photobioreactor involves many interdisciplinary subjects. The current research has not systematically understood and mastered the basic scientific principles and laws of its design, so it is difficult to form the core technology to solve key problems.
