    Beijing implemented one of the world's largest and most ambitious Thermal Hydrolysis Process (THP) programs for advanced anaerobic digestion starting in 2016. With five sludge treatment centers, this city-wide strategy now treats sludge from 13 water reclamation plants.

    This webinar offers a unique opportunity to explore the first decade of full-scale THP operation in Beijing, with direct insight from the R&D Director of Beijing Drainage Group.

    Participants will also get a behind-the-scenes look at the master planning and strategic decision-making that enabled a single advanced digestion technology to be successfully deployed across multiple treatment sites, with a unified biosolids outlet to land.

    Why Attend? 

    • Learn how Beijing selected, designed, and implemented a city-wide THP strategy across five sludge treatment centers.
    • Discover how high-quality biosolids from advanced digestion are utilized and understand the carbon impacts of this integrated sludge management approach.
    • Take away practical insights for utilities and planners considering advanced digestion or large-scale sludge strategy upgrades.
    • Live Q&A with Dr Zuliang Liao  

     

    Who Should Attend?

    This webinar is ideal for: 

    • Municipal leaders and utility decision-makers evaluating advanced sludge treatment technologies
    • Process engineers, technical specialists, researchers, and consultants with an interest in THP, anaerobic digestion, and biosolids optimization.
    • Wastewater treatment professionals seeking to improve sludge handling, performance, and long-term sustainability.
