Ultrasonic System to terminate Polluted Algae

Algae bloom has been recognized as an environmental problem since it significantly increases the water turbidity and causes serious taste and odor problems.

Field investigations in China have reported that microcystins in drinking water were one major factor that resulted in locally high incidence of liver cancer .When the eutrophic water is used to produce drinking water, algae cells consume high amount of coagulants and disinfectant, jam filters, generate disinfection byproducts, and deteriorate the water quality.Despite all efforts
, algal bloom, especially cyanobacterial overgrowth, remains a major problem in many lakes and reservoirs, and new engineering methods are needed to counteract excessive cyanobacterial growth in eutrophic waterbodies.

Ultrasound is known to have harmful effects on the structure and functional state of organisms. When applied to water, power ultrasound causes acoustic cavitation, in which millions of small bubbles collapse rapidly to reach temperatures as high as 5000 K and pressures as high as 100 MPa, so called ‘hot spots’, generate highly active hydroxyl free radical, and cause high speed micro-jets [9]. Such extreme conditions induce chemical reactions and enforce mechanic damages on substances in water, which has been widely employed to accelerate chemical reactions and to degrade environmental pollutants. A few studies have developed algae bloom control by ultrasound irradiation. It was reported that ultrasound effectively reduced the growth rate of algae by collapsing the gas vesicles that control the floating of the cells, fracturing the cells, and inhibiting cell division, and that the extent of algal growth reduction was influenced by ultrasonic parameters like frequency, intensity and time.
