4:00pm - 6:00pmXylem: Optimisation of large wastewater treatment plant’s operation
Energy efficiency – treated water quality – digitalisation

The efficient operation of large wastewater treatment plants is not only an economical but an environmental question as well. The European Climate Law has set the ambitious goal for Europe’s economy and society to become climate-neutral by 2050. The law also sets the intermediate target of reducing net greenhouse gas emissions by at least 55% by 2030. When water and wastewater utilities make up ~2% global greenhouse gas emissions, it is a unique opportunity for the water sector to lead global decarbonization efforts.

In the meantime the Urban wastewater treatment directive imposes tertiary and quaternary treatment in larger plants of 150 000 p.e. and above, by 2039 and 2045 respectively. When talking about treatment efficiency we can’t forget about the phosphorus and nitrogen removal. The limits set by the law are getting more and more strict. Existing facilities are challenged to comply considering the limitations linked to physical footprint extension and to short-term investments.

In 2024 we can’t neglect the importance of digitalisation in any industries. Wastewater treatment is not an exception neither. There is a wide range of solutions to digitalise some parts of the entire wastewater treatment plant, but what are the hands-on benefits, what is the ROI of the investment.

9:00am - 12:00pmNereda: Aerobic Granular Sludge for Large Wastewater Treatment Plants
Aerobic Granular Sludge (AGS) developed the last two decades into a widely applied modern variant for centralized activated sludge WWTPs and implemented up to multimillion person equivalents plant scale.

Goal of the workshop is to share current best-practices for AGS in large WWTP’s while facilitating dialogue, knowledge exchange and identification of potential beneficial future scientific & application developments.

In the workshop, owners and designers of several large AGS WWTP across the globe, will share their experience and lessons-learned and show how AGS reactor design and overall plant integrating was tuned towards coping with specific challenges. These include minimal energy/footprint consumption, extensive nutrient removal, salinity fluctuations and future load/treated water quality adjustments. Also hybrid plant integration to augment parallel activated sludge plants will be addressed, as well as plant integration with downstream membrane filtration to operate as AGS Membrane-Bio-Reactor.
