Programme Topics


Many utilities are now implementing this on a very intensive scale. As climate change effects become more pronounced, water quantity and quality are straining the ability of utilities to meet supply demands and quality criteria. Utilities across the globe are working with complex programs to interpret climate data and their effect on water systems. This session will present information on how these systems work and provide benefits.

The standard technology for water recycling for potable purposes is being challenged. RO is often seen as the panacea, but there may be combinations of other treatments that would be sufficient to achieve acceptable and safe water quality. This session will explore new treatment scenarios for IPR (indirect potable reuse) and DPR (direct potable reuse) systems and the technologies.

The Digital Water session will focus on evolving digital water technologies enabling water treatment and distribution, customer engagement, long-range planning, as well as a focus on the information management and data governance capabilities needed to pull it all together. l.

Research and technology development for improving desalination over the past decade has focussed on energy reduction. In recent years, large desalination plants have faced serious problems and even failures because of inadequate pre-treatment. This session will focus on recent developments and innovations with pre-treatment solutions for desalination.


The session focuses on novel concepts and processes that promote high effluent quality and resource recovery. Nutrient removal optimization continues to be an important challenge and much progress is being made for both organic and inorganic resource recovery. This session will also discuss the advance in novel technologies such as anammox, granular sludge, membrane aerated biofilms, algae systems, ion exchange, novel adsorbents, etc.

With the increased public concern related to pollution by emissions of microconstituents in effluents, water utilities have to evaluate the impact of these emissions on end users of water. This session will address modifications/conversions in wastewater reclamation plants and efficient technologies for the removal of these compounds.

This session focuses on recent advances in wastewater based epidemiology. Predictive intelligence on the detection and quantification of chemical or biological agents excreted by humans, which can be found in wastewater, are being used to gain information about general public health as well as an early warning tool, with the recent COVID-19 pandemic management being an example. Informations highlighting the application of wastewater based epidemiology at sewershed scale and in hotspots, and the benefits and challenges are welcome.

This session focuses on complex and high strength wastewaters that require specialized treatment technologies. The water industry is having to provide innovative technologies to treat streams such as industrial effluents, sludge liquors, black water and yellow water in centralised and decentralised facilities. Innovations and their applications will be considered for this session.
