To overcome current shortcomings in collecting microplastic waste in water systems, HKRITA has developed Acousweep, a new and sustainable wastewater treatment method to separate microplastics, significantly preserving the water quality. Acousweep utilises sweeping acoustic waves and a specially shaped chamber to trap and recover microplastic fibres effectively. Unlike existing filtration processes, the system enables continuous water treatment and easy collection of microplastic fibres by virtue of its acoustic manipulation technique.
