  • METHOD FOR PROMOTING THE RAPID PRECIPITATION OF TRAVERTINE CRYSTALS BY ALGAE
    Publication number: 20240190717
    Abstract: A method for promoting the rapid precipitation of travertine crystals by algae is disclosed. Microalgae is added to a body of water having a calcium ion concentration of 100-500 mg/L and stirred. The amount of microalgae is 0.1-8×108 cells/L. The invention adopts a method for promoting the rapid precipitation of travertine crystals by algae, which significantly improves the sedimentation rate of travertine crystals. At the same time, there are pseudomonas in the calcified water body of algae, which can be used for algae-lysing bacteria isolation and purification.
