Description

Water is vital for sustaining life on earth, and while population grows with projection to reach over 12 billion before the end of the century, the need to find sustainable fresh water supplies is ever growing. We need water for drinking, irrigation, energy production, various industrial activities, recreational activities, and even inland navigation. In many places in the world urbanization is a trend while in many cases this is stressing the need for natural resources. Many large cities, including megacities, that have been growing dramatically the last several decades are facing dramatic stress due to insufficient natural resources and effect of climatic changes. Water is on top of the list of such stressors. The need of water reuse is necessary and perhaps one of the few sustainable options to enrich and supplement available water supply sources. This session will focus on emerging aspects of water reuse for various purposes: irrigation, indirect potable reuse, direct potable reuse, replenishment of natural systems, water reuse in households and small communities, technology evolution and science in water reuse and many other topics. A more detail list of topics of interest in this session is provided below.  

  • Direct and indirect potable reuse 

  • Technological and scientific progress  

  • Treatment technologies and process treatment trains 

  • Role of advanced treatment technologies 

  • Regulations and policy 

  • Challenges in treatment and analysis of contaminants 

  • Pilot and full scale applications 

  • Pathogens and contaminants of emerging concern 

  • Protocols for water quality assessment 

  • Risk assessment  

  • Barriers to implementation 

  • Public perception and role of politics in water reuse 

  • Agricultural irrigation. 

  • Chemical and microbiological risks  

  • Contaminants of emerging concern: sources and fate related to agricultural irrigation (i.e., accumulation in crops irrigated with treated wastewater; presence in agricultural soils irrigated with reclaimed water) 

  • Analysis of contaminants in water, soils, crops in samples. 

  • Detection of antibiotic resistance bacteria (ARB) and genes (ARG) in disinfected wastewater and in soil  

  • Reuse of Grey water 

  • Aquifer recharge, including groundwater recharge with reclaimed water  

  • Recreational uses 

  • Water reuse in households and small communities 

  • Water reuse in arid climates 

 

Keywords: Water reuse, Emerging contaminants, New regulations for wastewater reuse, Reclamation, ARBs, ARGs, Risk assessment, Treatment trains, Advanced technologies.
