Effluent treatment can account for up to 5% of annual facility revenue, and sludge management may represent as much as 60% of that expense. For European companies, the pressure is escalating beyond just operational OPEX. Driven by the EU Green Deal and strict carbon neutrality objectives, facilities face aggressive mandates to reduce greenhouse gas (GHG) emissions by 55% by 2030 and achieve Net Zero by 2050. In this regulatory climate, sticking to short-term, easy-to-implement "adjustment measures" is a false solution; companies must embrace "transformational measures" that encourage long-term adaptation. Historically, industrial wastewater treatment has relied heavily on a reactive approach using inorganic metal salts,  which currently still represent around 90% of coagulant sales. These traditional chemicals are cheaper, effective, but they generate massive volumes of heavy, hard-to-manage sludge, driving up Scope 3 emissions from continuous disposal truck movements. Furthermore, manual chemical dosing reacts too late to sudden changes in wastewater quality, leading to inefficient processes, excess energy consumption, and high risks of off-spec discharge penalties. ## A pragmatic, proactive paradigm shift It is time to rethink wastewater treatment from a cost center into a driver of your sustainability agenda. Veolia has pioneered a proactive, integrated solution built on three pillars to secure stable compliance while drastically lowering your Total Cost of Ownership (TCO) and environmental impact: 1\. High-performance, sludge-reducing chemistry Veolia’s Hydrex\* and KlarAid\* plant-based coagulants utilize natural polymers from renewable sources to break FOG emulsions and coagulate solids without adding metals. By eliminating bulky metal hydroxide byproducts, these solutions can reduce overall sludge production by up to 50%.  However, transformation does not mean a blind abandonment of traditional chemistry. The reality of industrial water treatment is that using inorganic coagulants are still required in numerous situations, such as meeting specific regulatory limitations on phosphorus removal. The key is targeted innovation. Plant-based coagulants are the most suitable with Fat, Oil, & Grease (FOG) effluents, technically outperforming traditional metal salts in industries like dairies, edible oils, and refineries.  Crucially for your 2030 targets, an independent Life Cycle Assessment (LCA) verifies that these plant-based solutions offer a 4x lower overall environmental impact and a 59% reduction in global warming potential compared to traditional polyaluminum chloride (PAC). Even if a complete replacement isn't feasible for your specific plant setup, integrating a part of plant-based coagulants will always be a progress toward sustainability. 2\. Digital Intelligence for long-term predictability manual dosing is a guessing game that leaves your facility vulnerable to high load variations. By integrating TrueSense\* for Wastewater, you introduce feed-forward automation that continuously monitors influent and effluent water quality (total suspended solids \[TSS\]/turbidity) while automatically adjusting your chemical dosage. Combining the digital intelligence with the most relevant conditioning program helps secure the stability and the sustainable performance in the long term, preventing chemical waste, optimizing energy usage, and securing predictable compliance even during sudden production spikes. 3\. Dedicated expert teams. Chemistry and digital  alone are not enough. Designing a program that perfectly balances cost-effectiveness with your decarbonization goals requires deep analytical capabilities, long-track record lab jar-testing experience, and onsite presence. Rethinking wastewater is about selecting an expert partner who might get you out of your comfort zone but to define the most economically relevant and less environmentally impactful program that delivers value.  ## The true cost of inaction When evaluating a strategy, leaders must weigh the benefits and costs of action compared to the costs of inaction. What is your current annual spend on sludge disposal, and how many truck deliveries are contributing to your Scope 3 (indirect) emissions? What would be the financial and environmental impact if you could seamlessly reduce your sludge volume while fully automating your chemical feed? Transformative wastewater treatment is not just a regulatory safeguard to meet your 2030 EU obligations; it is a competitive advantage that optimizes your operational savings today. Are you ready to see the difference firsthand? Reach out to a Veolia expert today to hear about real life examples. Schedule a TrueSense\* site survey to assess your automation potential, and/or to request a jar test on your actual wastewater to visually demonstrate the dramatically lower sludge volume our integrated approach can achieve.  #  \> Discover the Chemistry behind 50% less Sludge \<    # [![\CONTACT AN EXPERT\](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/25605683/interactive-415858033888.png)](https://blog.kruger.dk/hs/cta/wi/redirect?encryptedPayload=AVxigLJEi%2B0gn%2Bx6LRipDd9eqR2VAAhlb2liZAEro78%2BY2IVv%2FN%2FM7o7bvtS8MfEwLoxU5NAWU1qM2yf1rxc4l5vY%2BZwoxtt8VSER%2BYZ92MmiI5K8Yx1HdynGhHVDUBoGOdYL%2BoJdhs2WHBbyoO6G2RMdzTSI43kuJiIdcIHStI4zJIzC4Egt9lM73sQn7u9&webInteractiveContentId=415858033888&portalId=25605683&hsLang=en-ee) ## Tags - [Industry](https://blog.kruger.dk/?tid=422349641919) - [Municipal](https://blog.kruger.dk/?tid=376204583154) - [Wastewater treatment](https://blog.kruger.dk/?tid=239914143957) ## Related articles ![Subscribe](https://blog.kruger.dk/hubfs/vwt-uk/subscribe.jpg) ## Sign up to blog notifications Receive the latest blog updates. {|error|} By checking this box, you agree to **Veolia Water Technologies's** [Privacy Policy](https://www.veoliawatertechnologies.com/en/privacy-policy-veolia-water-technologies) and you agree to receive information on our products and services.
