(don't) Waste Water! | Water Tech to Solve the World

❓ Ever wondered how the #WaterIndustry was reacting to our World's Water Challenges? Water Scarcity? #SDG6? PFAS? Climate Change? Circular Economy? Digitization and Smart Water? 💪 Get the Water Market pulse for free. In one hour per week, while you do the dishes! 📈 We talk water investment, water tech, water entrepreneurship and water market with entrepreneurs, thought leaders, book authors, scientists, investment funds, VCs, and C-Level experts from water majors. ➡️ Leverage their insights, advice & experience and ensure to stay on top of best practices 🗓️ Tune in every Wednesday (don't miss out! 😅) 🌐 Find all the detailed episode notes, interviews, infographics, and more at http://dww.show Currently in its 10th Season, the "(don't) Waste Water" podcast has already welcomed around 250 guests from Water Majors (SUEZ, Veolia, Jacobs, Xylem, Kemira, Evoqua, Aquatech, SKion Water...), Scale-Ups (Cambrian Innovation, Epic Cleantec, Gradiant, Liqtech, 374Water, Gingko Bioworks...), Start-Ups (Puraffinity, KETOS, 120Water, ZwitterCo, Membrion, Source...), Universities (Berkeley, the Columbia Water Center), Investment Funds (Sciens Water, Mazarine, Burnt Island Ventures...), Business Accelerators (Imagine H2O, Elemental...), Book Authors (Seth Siegel, David Sedlak, David Lloyd Owen...) or Market Intelligence Companies (BlueTech Research, Global Water Intelligence, World Bank, OECD, Isle Utilities...). Or simply water legends like Gary White, Mina Guli or Andrew Benedek! On the "(don't) Waste Water" podcast, I strive to make the Water Industry easy to understand for everyone, starting with water professionals, executives, and investors. Hence, he opens the microphone to seasoned, inspirational water experts to discuss their field of excellence. No one can claim an all-around in-depth understanding of a matter as complex as Water. But piece by piece, you can rebuild the puzzle. With curiosity, patience, and passion, Antoine Walter explores topics such as Advanced Treatment Technologies, Water-Energy Nexus (Hydrogen, Lithium...), PFAS removal, Nature-Based Solutions, Wastewater Reuse, Distributed Water Treatments, Water Finance, and Water Entrepreneurship. I actually firmly believe that regular listeners of the "(don't) Waste Water" podcast may, in the end, claim a "Water MBA!" A particular field of interest is how innovation forms, grows and gets widely adopted in a complex and conservative field like the Water Industry. This may be one of the keys to achieving the United Nations Sustainable Development Goal n°6 - #SDG6. Oh, and in short, about me: I'm a water engineer turned avid student of the water business, market, finance, and tech. I'm married, a happy father of three, and I'm French (nobody's perfect 😅).

    Water Industry Trends 2025: What 153'482 LinkedIn Ads Reveal

    Wanna see the Future of the Water Industry? Listen to this! More #water insights? Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ A big thanks to my sponsor, SimpleLab! https://gosimplelab.com/ I know the future - so let me share it! Indeed, yes, I did it again: I drowned myself in 153'482 LinkedIn ads for the keywords "Water" and "Wastewater" from Q2 to Q3 2024 (using a “slightly homemade” scraping approach - please forgive me, LinkedIn!). I did so, looking for the signals companies believe will make them money in 2025 - that's how I know the future. Why ads, you ask? Well, for a simple reason: businesses rarely burn ad budgets on dead-ends. So, if they’re paying to talk about it, they must see an ROI! Here’s the executive summary of what I learned: that's hopefully enough to give you plenty of conversation starters and investment hints! 🎙️ Subscribe and Listen to the Don't Waste Water Podcast HERE 🎙️ Podcast Channel: @dwwpodcast Main Channel: @AntoineWalterDWW Smartlink: https://smartlink.ausha.co/dont-waste-water Website: https://dww.show/podcast/ 🙋 QUESTION: What would you like me to cover next? ⏰ TIME CODES ⏰ 00:00 Why and How I Investigated LinkedIn Ads 07:27 Where is the Real Money Flowing? 10:44 What's behind the buzzword Innovation? 13:53 Which water crisis are companies betting on? 17:03 Sponsor: SimpleLab 17:56 Who's Hiring?

    S12E9 - How Altillion's Liquid-Liquid Technology Redefines Resource Recovery

    Liquid-liquid extraction technology, when implemented innovatively, can transform lithium extraction by dramatically reducing costs and environmental impact! Wanna understand how? Listen to this!

Check them out ➡️ https://gosimplelab.com/ #️⃣ All the Links Mentioned in this Video #️⃣ Altillion's website: https://www.altillion.com/ Connect with Jay Keener on LinkedIn: https://www.linkedin.com/in/jay-keener/ My conversation with Chris Wyres from Evove: https://smartlink.ausha.co/dont-waste-water/s9e7-how-to-eradicate-dead-zones-cut-energy-needs-by-80-and-double-lithium-selectivity 🎙️ Subscribe and Listen to the Don't Waste Water Podcast HERE 🎙️ Podcast Channel: @dwwpodcast Main Channel: @AntoineWalterDWW Smartlink: https://smartlink.ausha.co/dont-waste-water Website: https://dww.show/podcast/ 🙋 QUESTION: What would you like me to cover next? ⏰ TIME CODES ⏰ 00:00 Introduction and Background 02:04 Startup Life in Watertech 04:35 Deep Dive into Liquid-Liquid Extraction 10:46 Jay Keener's Entrepreneurial Journey 15:05 The Story of Xedia Process Solutions 22:14 The Birth of Altillion 29:04 Altillion's Focus on Lithium Extraction 34:11 Collaboration with DLE Companies 41:40 Pilot Projects and Future Plans 54:11 Rapid Fire Questions 🔄 Traditional solvent extraction requires 5-7 stages with minutes of residence time per stage - Altillion achieves better results in just 2 stages with seconds of residence time 🧪 Recovery efficiency remains consistent regardless of starting concentration - they can extract lithium down to 3-4 ppm whether starting from 20 ppm or 2000 ppm 💰 The focus in lithium extraction is shifting from OpEx to CapEx reduction due to high interest rates and financing challenges 🤝 In nascent industries like lithium extraction, collaboration between "competitors" often creates more value than pure competition 🏭 What looks like a complex water treatment flowsheet is actually a simple mining/oil & gas project by industry standards 🔄 While most companies scale up their pilot plants, Altillion actually built a smaller second pilot unit because their first one was too large for potential partners' testing needs. 🧪 Despite being based in Texas with deep oil & gas expertise, they shifted focus away from oilfield brines toward mining brines - not because the technology didn't work, but because it worked too well, extracting even trace amounts of lithium effectively.
