 Good morning everyone and welcome to IWA's first-ever Digital World Water Congress. Good evening, good afternoon and good evening to you all. Greetings to all of you online, wherever you may be. We're so glad that you're participating in our first virtual congress as we at IWA strive to adapt to the restrictions and rise to the challenges brought about by the current pandemic. One water, the circular economy of water, integrated water resources management. All of these terms have one thing in common. It's the recognition that we're going to have to increasingly access new forms of water that we thought previously were unusable and that we're going to have to pay more attention and be more systematic thinking about the impacts of our use of water and other people in the downstream environment. First, we will enhance promotion of water conservation for education and enhancement measures on increasing water use efficiency. The fibre optical cables installed in the wastewater pipe are pulsed with a laser. The detector, end of the DTS unit, captures this light, records and stores it. Here offer the new insights into optimized asset management. I can say that it is possible to use this flexibility in the algae composition for the wastewater treatment process and it is also possible to react to environmental changes. Within our model, then we can estimate how the chemical will partition between the solid and the water phase, as well as the water and the air phase. And once we have this, we can make a simplifying assumption. Greenhouse gas emissions taking center stage about so many of the discussions on net zero targets. Those from solid copper electrodes, which actually enables dosing at very low range and a flow proportion to water to the treatment. Low oxygen conditions promote biologic conserves catalytic iron oxidation and removal in filters, which means that filters can be operated at higher filtration rates. With regards to iron, I wouldn't be so concerned. Ammonium, I would definitely see a delay, especially moving from first step of nitrification to the second. I am extremely happy and honored to be the recipient of such a prestigious award. I have been an IWN member for around 35 years and I always felt very well received and embraced all the activities I had with the association. The thousands of women leaders we know and work with us are not stuck in the past. For them, reviving traditional systems of rainwater harvesting and conservation is also about innovating sustainable approaches. We live in extremely challenging times. I'm speaking to you from India where COVID-19 has ravaged cities and religious alike. But unsafe water also affects hundreds of millions, here and worldwide. I'm indeed deeply honored for IWT to have been selected as the recipient for IWU's Professional Development Award 2021. Justice climate change has sparked grassroots activism across the climate. Another crisis too requires massive mobilization of people who truly care about our shared future.
