Closing the water cycle through efficient and innovative technologies

Call for papers for the 19th IWA LET

Submitting a paper for LET 2024 gives you an opportunity to present your work to a global audience and the opportunity of publication in a leading international peer-reviewed journal.

The conference technical programme will consist of platform presentations, poster presentations, workshops and panel discussions.
All outline papers selected for presentation will be included in the online preprint – which will be accessible to all conference delegates.
Full papers from a selection of presentations will also be considered for publication in one of the IWA Publishing journals. Selected posters will be on display for the duration of the conference. Outline papers are now invited on the respective topics and should be submitted via our conference website.

Outline papers will be accepted for oral or poster presentations and shall be limited to a maximum of two A4 pages (including figures and tables). The outline paper has to contain adequate information to allow for a sound review. To submit your outline paper please click here.

The submission deadline for outline papers is 15 December 2023. Submissions will be peer-reviewed and authors will be notified of the decision on their paper following the final meeting of the Programme Committee by 31 January 2024.

LET 2024 Themes

Joint Water and Wastewater Themes

Closure of the water cycle is crucial to ensure sustainable water resource management by minimising waste, optimising resource utilisation, and addressing the growing challenges of water scarcity and pollution. This session explores innovative approaches in water and wastewater treatment, aiming to minimise waste and maximise resource recovery. Advanced technologies, policies, and collaborations that bridge the gap between water supply and wastewater treatment and promoting technologies for water reuse will be discussed.

Increased awareness of micro-contaminants and improved analytical techniques have led to stricter regulations and increased public awareness that will drive better removals of micro-contaminants. Removal of these trace compounds can be demanding, and innovations are being developed and implemented to make advanced processes more effective and sustainable. This session will explore these innovations and the implementation aspects of micro-contaminant removal and will cover both water and wastewater.

Water Themes

Enabling more direct and real time data, digitalization can greatly enhance treatment performance with respect to energy and efficiency. There are recent advancements in sensor technology that can give critical feedback to improve system operations and optimisation. This session will show recent advancements and how they are applied in real systems.

New materials are continuously being introduced into membranes to increase removal of contaminants, increase flux and decrease energy demand. A major area is the development of catalytical membranes that may be able to degrade micro-contaminants on membranes surfaces. Other developments include hybrid or integrated systems where the membrane works with a complementary treatment to produce enhanced results.

Higher energy costs, climate change and population growth are driving research and innovations on improving the reliability and performance of desalination. New technologies and integrated systems are developed to reduce the high energy demand of desalination while maintaining low footprint. This session will cover methods to reduce energy demand and increase reliability of desalination.

Wastewater Themes

Wastewater treatment is moving towards net-zero processing and integration in a more circular economy. Recovery of resources (nutrients, chemicals, energy etc.) is getting implemented in new treatment plants. This session will show developments in the field and highlight the integration of resource recovery of chemicals and nutrients within wastewater treatment.

Wastewater treatment is moving towards climate neutrality. This requires limiting emission of greenhouse gases (CH4, N2O and CO2) while at the same time energy management (minimisation and recovery) has to be improved. This session will discuss the latest developments and innovations.

Wastewater treatment processes keep being innovated. New technologies (such as MABR, Granular Sludge, MBR, etc.) will be discussed on their technical merits and practical implementation.

The IWA Leading Edge Conference on Water and Wastewater Technologies is designed to be the place for sharing the latest insights into how pioneering science, technological innovation and leading practices will shape the major transformation in water management that is underway.
