LET 2023 Topic Summary


Manufacturing process are water demanding and the water quality requirements for advanced facilities is very demanding. At the same time industry is faced with economic challenges and tightening regulations with regard to water use and waste generation. This has led to the rapid development and adoption of novel and advanced technologies.

For decades the water industry focused on technologies that can effectively remove contaminants and pathogens. While there are many treatment technologies that can achieve any desired water quality, there is now a shift toward achieving treatment objectives in a far more sustainable way. This means specifically toward carbon emissions, energy reductions, higher water recovery, resource recovery and reduction in chemical use.

With conventional inland sources being used to their maximum extent, seawater is becoming a major target source. Treatment of seawater is very challenging involving desalination (which is very energy intensive) and the pre-treatment step which is problematic due to the high algae content of seawater. One element that will be covered is mineral recovery. Technologies are continuously being developed to overcome these problems.

New scientific developments are leading to new water technologies that can achieve multiple objectives in a single step. These include new materials, novel membrane systems, catalytic membrane systems and ion exchange for removing organics.


The anthropogenic release of greenhouse gases (GHGs), has been demonstrated to be a major contributor to climate change, and like other industries, the water sector must reduce GHG emissions. This session will provide a better understanding on the quantification of GHG in wastewater related processes as well as strategies for reduction, mitigation, transformation and abatement towards achieving Net-Zero targets.

Increasing uncertainty on the energy market including supply, resilience, and costs are a big concern for the water sector, together with decarbonisation. Innovations on renewable energy and heat production in wastewater treatment plants are moving at a fast pace with significant developments in the water and sludge and gas lines. This session focuses on energy generation, recovery and balances from heat, electricity, hydrogen, ammonia, sludge, using innovative technologies in wastewater treatment plants.

Current pressures faced by the water industry have highlighted how innovation and the next generation of technologies can solve real problems whilst, meeting tight regulations but bringing added economic benefits by comparison to state of the art. The session addresses big questions on the innovative technology options for mainstream and sidestream, nutrient management, resource recovery all the way to persistent pollutants

The water industry is leading the way making sustainability pledges, to become greener, taking in consideration the local economy, society and the environment backdrop. New technological solutions are delivering reduced greenhouse emissions, benefits to the local communities and the environment. The session provides and overview of solutions for large and small WWTP and communities, including aspects on footprint, emissions, resource recovery, green walls, etc.

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.
