Ultrasound-assisted coagulation for Microcystis aeruginosa removal using Fe₃O₄-loaded carbon nanotubes.

ABSTRACT: Harmful cyanobacterial blooms are increasing environmental issues and require novel removal technology since the required doses of algaecides may cause further environmental pollution or treatment facility damage. Herein, we firstly introduce the combination of ultrasound and Fe₃O₄/CNTs as an alternative strategy to enhance coagulation for the removal of Microcystis aeruginosa cells in water. It remarkably enhanced cyanobacterial cell removal and microcystins control, compared with sonication alone (40 kHz ultrasonic bath, 4.2 mJ mL^-1). 94.4% cyanobacterial cells were removed using 20 second sonication with 20 mg L^-1 Fe₃O₄/CNTs, Al₂(SO₄)₃ coagulation (20 μM). Both sonication time and c
