The global event for water professionals.

The IWA Leading Edge Conference on Water and Wastewater Technologies is designed to be the place where new ideas are introduced and the opportunity is provided to interact with the “best of the best”. This is the global conference where new insights into how pioneering science, technological innovation and leading practices shape the major transformation in water management that is underway.

The LET conference is held in a different country every year. After unparalleled success in Amsterdam (2003), Singapore (2007 & 2009), Zurich (2008), Phoenix (2010), Amsterdam (2011), Brisbane (2012), Bordeaux (2013), Abu Dhabi (2014),Hong Kong (2015),  Jerez de la Frontera (2016), Florianópolis (2017) and Nanjing (2018) IWA is hosting its 16th Leading Edge Conference on Water and Wastewater Technologies in 2019 in Edinburgh, UK, which complements the approaches of urban water management between megacities, smaller towns and rural environments, driven by the diversity of climatic conditions and the natural and human environment.

Programme Topics

The LET 2019 taking place in Edinburgh, United Kingdom, will cover 8 programme topics:  Micro-contaminant Control in Drinking Water; Novel Disinfection Technologies; Advanced Membrane Applications in Drinking Water; Recent developments to improve Desalination; Energy efficiency and Resource Recovery in Wastewater Treatment; Emerging Contaminants: Microplastics, Pharmaceuticals and Personal Care Products (PPCP) and Antibiotic Resistance; Emerging Technologies for Nutrient Removal and Sludge Management – including energy generation.

In the past 5 years there has been significant increased concern by utilities and the public about micro-contaminants in drinking water. This is part due to improved detection methodologies and increased production of pharmaceuticals and chemicals. This session will focus on the detection and advanced treatment technologies to remove target compounds.

There is a need for novel microbial control approaches that enhance water safety and minimize formation of harmful disinfection byproducts and harmful bacteria in drinking water systems. This session focuses on innovative materials and approaches, informed by microbial ecology and techno-economic constraints, for the control of harmful bacteria in drinking water and biofilms.

In the past decade there has been much focus on the development of specialized materials for membranes applications for the treatment of drinking water. However, in reality very few of the developments have been applied in working systems. This session will focus on advanced membranes using alternative materials that have been successfully employed in-situ.

Across the world there has been considerable investment to find alternative approaches to high-energy demanding desalination. This session will focus on creative system solutions and advanced salt separation technologies.

The session will focus on novel concepts and processes to improve environmental efficiency of wastewater treatment plants by either optimizing energy efficiency or resource recovery. Papers that discuss technoeconomic life cycle assessment (LCA) or economic aspects are also invited.

With the increased public concern related to pollution by emissions of microconstituents of effluents, water utilities have to evaluate the impact of these emissions. This session will address conversions in wwtp’s and efficient technologies for the removal of these compounds.

Nutrient removal optimization continues to be an important challenge. This session will discuss the advance in the development of novel technologies such as anammox, granular sludge, membrane aerated biofilms,algae, ion exchange, absorbents etc. Technologies aiming at reaching very low nutrient effluent concentrations are also invited.

Waste activated sludge management is one of the main cost factors for wastewater treatment. The session will discuss all aspects of sludge management (including dewatering, digestion, hydrolysis, disintegration,advanced thermal processes etc.) including the handling of sludge liquors and biogas.
