Plasma bubbles for algae control

Algal and cyanobacterial blooms incur current treatment challenges such as high operational cost, disinfectant by-product formation, and the requirement to separate oxidants from solution after the oxidation. Advanced oxidation methods, such as cold plasma activated bubbles (CPAB), have the potential to overcome the current challenges . CPAB are bubbles containing partially or fully ionised gas that utilise the ambient condition of gas and an electric discharge to produce and deliver highly reactive oxygen and nitrogen species, such as ozone, hydrogen peroxide, hydroxyl, superoxide, and nitric oxide radicals. This project will examine methods to optimise the application of CPAB across a range of algal and cyanobacterial species to increase its technology readiness level.
