Real-World Impact on Sustainable Raw Water Treatment Technology
Prof. Irene LO’s Research Team and Water Supplies Department Won 2024/2025 HKIE Best Environmental Paper Award for Pilot-Scale Phosphate Removal System for the Cleanup of Local River Water
Prof. Zhang Xiangru discovers an effective and rapidly degradable disinfectant. Using the instrument known as “ultra-performance liquid chromatography/electrospray ionization-triple quadrupole mass spectrometry (UPLC/ESI-tqMS)”, he successfully detects the degradation products of 2,6-DCQ and determines the degradation pathway of 2,6-DCQ in seawater.
