A novel application of ultrasonic irradiation for rapid control of blue-green algae (BGA) bloom was investigated. Potassium iodide (KI) experiments demonstrated that frequency and input power are the major factors that affect the ultrasonic irradiation intensity. Short exposure (3 s) to ultrasonic irradiation (120 W input power, 28 kHz) effectively settled naturally growing BGA suspension. Electron microscopy reconfirmed that sedimentation was caused by the disruption and collapse of gas… Expand

Results showed that the reduction in algal numbers is dependent on both frequency and intensity, suggesting that ultrasound can offer a suitable method for algae inactivation or control but the sonication conditions must be taken into account. Expand

By incorporating the ultrasonication process with the on-going strategy, particularly flushing with induction water, cyanobacterial blooms can be controlled effectively and a significant improvement in the conditions of the lake was attained. Expand
Cavitation mechanism in cyanobacterial growth inhibition by ultrasonic irradiation
Abstract To prevent cyanobacterial bloom in eutrophic water by ultrasonic method, ultrasonic irradiations with different parameters were tested to inhibit Spirulina platensis from growth. TheExpand
Algal Control by Low-Frequency, Low-Power Ultrasonic in Eutrophic Water Bodies
Ultrasonic cavitations can control algal growth. Considering water ecosystem protection and characteristics of ultrasonic technology, low frequency and low power ultrasonic was especially suitable toExpand
Removal of Algae by Sonication-Coagulation
The results showed that ultrasonic pretreatment significantly enhanced the removal efficiency of algae cells in water treatment works, and significantly reduced the sample turbidity. Expand
Influence of ultrasonic intensity on sinking of Microcystis colonies and their floating process under different light and temperature conditions
Inhibition effect of different ultrasonic intensities was investigated by using Microcystis colonies from Lake Taihu, and the aim of this study was to obtain the optimal ultrasound parameters. TheExpand
The use of ultrasonic frequencies to control the bloom formation, regrowth, and eco-toxicity in Microcystis aeruginosa
Results suggest that ultrasonic frequencies between 869 and 1137 kHz are effective at controlling bloom formation in M. aeruginosa after sonication, but not at controlling microcystin-LR concentrations and its adverse effects on D. magna. Expand
Ultrasound-enhanced coagulation for Microcystis aeruginosa removal.
The results show that sonication significantly enhances the reduction of algae cells, solution UV254, and chlorophyll a without increasing the concentration of aqueous microcystins, and this method could be successfully applied to natural water containing multiple species of algae. Expand
200 kHz Sonication of Mixed-Algae Suspension from a Eutrophic Lake: The Effect on the Caution vs. Outbreak Bloom Alert Levels
For effective ultrasonic algae removal, several studies have considered the ultrasound equipment linked factors, such as power and frequency. However, studies on the response of mixed algal culturesExpand
