Procedure for submission
The following sequence of actions is the only method for submitting material for an oral or poster presentation at LET 2027.
You are asked to submit an outline paper, whether you intend to give an oral or poster presentation.
The maximum length of your outline paper is to be 2 pages (A4) of text, plus 2 pages (A4) of figures, tables and references.
All submissions must include:
• A title that clearly expresses the subject of the paper
• All authors’ names and affiliations
• Contact information (name, designation, email address, postal address, and phone number) of corresponding author
• Type of presentation (oral or poster presentation)
• Theme of your presentation
• Short abstract summary, which should not exceed more than 10 lines
• No more than two A4 pages of an outline paper that must contain adequate information to allow a sound review: an introduction, concise details of methods and results, and conclusions

LET 2027 themes
Joint Drinking Water and Wastewater Themes
Digitalization for process-automation
Access to direct and real-time data, digitalisation, automation and AI 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 feature such advancements and how they are applied in real systems.
Advances in applications and development of ceramic membranes - Efficiency and hybridisation
Ceramic membrane applications globally are exhibiting increasing growth across drinking water, water reuse and desalination. Operating conditions of ceramic membranes for these applications can vary widely while the pros and cons of operation and hybridisation are poorly understood. This session will cover the wide range of emerging applications and membrane materials.
Drinking Water Themes
Augmenting drinking water by potable reuse
Augmenting drinking water supplies by water recycling is a growing practice. Recent developments towards potable reuse favour non-membrane-based hybrid solutions for inland
communities in comparison to high-pressure membranes in coastal settings. This session explores innovative approaches in providing cost- and resource-efficient, practically operable treatment promoting technologies for potable water.
Nature-based technologies
Recent advances in biotechnology, in particular use of genomics, and in-situ sensors as well as an increasing pressure to reduce
energy requirements and carbon footprint of water treatment and reuse technologies have resulted in new developments using nature-based technologies. This session will feature the latest developments of nature-based technologies to target trace organic chemicals and pathogens for treating impaired water resources, (grey)water reuse and RO brine management in water recycling projects. The integration, reliability and energy demand of these technologies or hybrid solutions will also be of interest.
Wastewater Themes
Advanced treatment in wastewater treatment plants
Advanced treatment to remove micropollutants is now moving from specialist application to a major
implementation challenge for wastewater utilities. The recast Urban Wastewater Treatment Directive is accelerating adoption in Europe, and similar regulations are being implemented globally. Concerns over pharmaceuticals, pesticides, household and industrial chemicals, and antibiotic resistance are increasing demand for robust treatment barriers. This session focuses on innovations and technologies for micropollutant management and removal by advanced treatment, with emphasis on implementation and high-impact case studies.
Greenhouse gas emissions in wastewater treatment plants
Greenhouse gas emissions from wastewater treatment plants are now a leading-edge technology challenge because N₂O, CH₄ and direct CO₂ emissions are dynamic, site-specific
and strongly shaped by process disturbances, microbial pathways and real-time operating conditions. The impacts of carbon taxation on decision making are uncertain and
challenging. This session focuses on next-generation technologies that move beyond measurement campaigns towards predictive emissions, mitigation and abatement. Topics include all emissions process control, microbial and pathway-level diagnostics, intensified nitrogen removal with low N₂O risk, emerging N₂O abatement technologies, dissolved methane capture and conversion, and technologies that can verify emissions reduction at full-scale while maintaining treatment performance.
Resource recovery
Resource recovery from wastewater is strategically important as utilities respond to nutrient security, fertiliser price volatility, water scarcity, energy neutrality and circular manufacturing. The challenge is no longer only to demonstrate recovery, but to implement technologies at scale. This session will focus on recovery from wastewater, process streams and brines, including nutrients, cellulose, biopolymers, volatile fatty acids, organics, water, heat, biogas upgrading and syngas production, with evidence from pilot, demonstration and full scale implementation in wastewater treatment plants.
Advanced solids management
Sludge management is a major technology priority as conventional routes face increasing pressure from PFAS, microplastics, antibiotic-resistance genes, land-application restrictions, energy costs and public acceptance. This session will focus on technologies for sludge treatment, stabilisation and volume reduction, including advanced digestion, hydrolysis, dewatering, drying, pyrolysis, gasification, hydrothermal processes, supercritical water oxidation and contaminant- destruction approaches. Contributions should emphasise process performance, contaminant fate, energy balance, emissions and practical evidence from pilot, demonstration and full-scale implementation.
