The Hong Kong University of Science and Technology (HKUST) research team has developed a groundbreaking wastewater treatment technology that integrates a mesh bioreactor with an ultrasound-induced transient cavitation cleaning mechanism. The system can complete mesh cleaning within 3.8 seconds under anaerobic conditions and achieves 10-20 times higher flux than conventional membrane bioreactors (MBRs). The technology operates efficiently with substantially lower energy consumption, produces treated effluent surpassing international and local discharge standards, and reduces the cost of treating each cubic metre of wastewater to 50% of conventional MBRs, offering a sustainable solution for both municipal and industrial wastewater treatment.
