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) and  Florianópolis (2017) IWA is hosting its 15th Leading Edge Conference on Water and Wastewater Technologies in 2018 in Nanjing, China, 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 2018 taking place in Nanjing, China, will cover 8 programme topics:  Innovations in direct potable reuse; Advances in energy efficiency and resource recovery in wastewater treatment; Innovative decentralized technologies for urban/rural applications; Emerging Contaminants and Antibiotic Resistance – detection and control; Advanced oxidation processes for water and wastewater treatment; Advanced materials and membranes for water and wastewater treatment; Sustainable treatment of complex industrial wastewater streams; Recent developments and applications of advanced molecular microbial tools in water and wastewater treatment

With population expanding and increasing urbanisation, water scarcity strongly increases and the only option to alleviate the scarcity is often
direct potable reuse. The treatment schemes are almost always driven by public perception and fear, rather than science. With increasing knowledge and detection of contaminants coupled with advanced technologies there is a movement towards a more scientifically credible treatment paradigm. This session will look at how technologies can be integrated together to achieve potable drinking water directly from wastewater.

Wastewater can become a source of value and economic gain if its treatment is re-oriented to emphasize the recovery of water, energy, nutrients, and, in some cases, other materials. This session focuses on emerging processes and systems with a primary goal of recovering resources present in “used water”. Examples include direct anaerobic treatment to give a net energy output; nitrogen and phosphorus separation and concentration to provide high value fertilizer feedstock; water reclamation for beneficial use; and recovery of other materials, such as metals and fiber.

Decentralization is an alternative to extend the coverage of existing urban water and wastewater systems, solve the problems of unsafe water supply and poor sanitation in rural regions, and facilitate onsite water and material recovery and reuse. The technologies widely applied for centralized systems may not always be suitable for smaller scale decentralized systems with more diverse system installation. This session will present research and practical application of leading-edge technologies for decentralized systems in urban/rural areas, with a focus on technologies for source separation, treatment, onsite reuse, risk control, and best operation/maintenance.

Water quality is threatened by chemical micro-pollutants of emerging concern, such as pharmaceuticals, personal care products, or endocrine disruptors, and also emerging pathogenic microorganisms, including chlorine- and UV-resistant viruses and protozoa, and antibiotic resistant bacteria. Although there is still a lack of quantitative data on their effects on ecological and physiological processes, and especially on human health, the detection of these contaminants in natural waters and wastewater treatment plant effluents raises concerns about the efficiency of current treatment processes. This session focusses on innovative technologies for the control of emerging contaminants in water and wastewater.

We are facing challenges in removing micropollutants, such as pesiticides, PPCPs and PFCs, in source water and bio-refractory compounds in industrial wastewater, including coking wastewater, pharmaceutical wastewater, fine chemistry wastewater.Recently, significant progress has been achieved in the AOP field, particularly in the development of plasma oxidation and catalytic oxidation. This session will provide a platform for exchanges on the progress of recent developments in these technologies, and the experiences of the application in water and wastewater treatment.

Novel materials and multifunctional membranes are making significant improvements in the way we treat water and wastewater. Nanotechnology utilizes materials at the nanometer scale, whose unique properties enable novel functions, and is being actively pursued to enhance various treatment applications such as adsorption, catalysis, membrane separation and sensing. In addition, advances in membrane materials continue to innovate separation processes, whose application is becoming increasingly common in water and wastewater treatment systems of different scales. This session will address the development and application of advanced materials to enable a shift of treatment paradigm from the current chemical and energy intensive processes to high efficiency, physical and catalytic processes that minimize chemical and energy use as well as waste production.

Wastewaters from many industries contain complex mixtures of organic and inorganic components, especially generated where centralized treatment of industrial wastewaters together with domestic wastewater is common, making treatment challenging. While biological treatment is generally the most cost-effective form of wastewater treatment, it’s often compromised because some of those components are recalcitrant to biodegradation and even toxic to microorganisms. This session will present research and practical results for novel biological, chemical, physical, and combined means that overcome the roadblocks to successful treatment. Emphasis will be given to techniques that yield effective treatment that is energy ans financially sustainable.

Biological treatment systems are engineered to select for a few functional microbial groups that may be organized in spatial structures. Conventional microbial techniques can only show a relatively small proportion of the total diversity. Recently, molecular approaches have circumvented these limitations, allowing us to obtain a more detailed image of microbial communities, which may be useful for processes diagnosis/optimization. This session will document how the recent developments and applications of advanced molecular tools are providing deeper insight into the structure and function of microbial communities used to treat water and wastewater, as well as how those new insights lead to improvements in process performance.
