Extend Bioreactor Lifespan in Wastewater Treatment
Using the Bio-produced Sulfide as Antifoulant Chemical to Reduce Membrane Fouling Problem
Tags: The Hong Kong University of Science and Technology, Hong Kong, Energy & Environment
This wastewater treatment method not only controls membrane pollution in bioreactors through sulfide production from sulfate reduction but also upcycles waste by transforming sulfate-containing wastewater into valuable sulfide. The primary aim is the innovative management of membrane fouling, substantially increasing the bioreactor's lifespan and decreasing maintenance needs. Secondary outcomes include the efficient removal of organics and significant sludge reduction, thanks to enhanced solid-liquid separation and optimized bacterial growth conditions. This process ensures nearly zero effluent suspended solids and turbidity, highlighting its efficiency. By prioritizing membrane health and integrating waste upcycling, this technology offers a sustainable solution for wastewater management.
