Abstract
Blooms of microalgae can pose a major threat to ecological balance and human health. Therefore, a novel method of harvesting microalgae was investigated, using re-frying oil to make buoy-bead for the harvesting process. The effectiveness of the method was evaluated by water samples from the Huaihe River basin and Chaohu Lake. The results showed that the buoy-bead flotation method achieved a harvesting efficiency of 97.21 %.The climate change emissions for harvesting 1 m3 of microalgae are 0.33 kg CO2 eq, and with a positive NPV, the economic feasibility of the microalgae harvesting plan is preliminarily assessed.
期刊介绍：
Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
