Yesterday, the board of Middelfart Spildevand A/S visited our HECLA® Setores plant at Søndersø Renseanlæg to see what #pyrolysis looks like in action.   With the coming revisions of the EU’s Urban Wastewater Directive and the Sewage Sludge Directive, water utilities across the EU must meet new requirements for measuring and eliminating #PFAS to meet defined limit values.   By pyrolyzing #sewagesludge under #AquaGreen’s process conditions, PFAS is eliminated in both #biochar and flue gas from the sludge, making pyrolysis a gamechanger in the battle against ‘forever chemicals’.   Learn more about what the legislative future for #sludgemanagement and #wastewatermanagement in the EU holds here 👇   Proposal for a Directive of the European Parliament and of the Council concerning urban wastewater treatment (recast) - https://lnkd.in/dF4Zy6ge

Warrenpoint WwTW Phase 2: NI Water investment building on the work of the EU-funded SWELL Project, providing enhanced treatment to further improve water quality in Carlingford Lough. Warrenpoint is a small town in Co Down on the northern shore of Carlingford Lough, approximately 7 miles south-east of Newry. The shared water of Carlingford Lough marks the border between Northern Ireland and Ireland. Warrenpoint is popular with day trippers and the town can experience an influx of visitors during the summer months. Originally constructed in 1976, the works serves Warrenpoint itself and the neighbouring villages of Rostrevor and Burren. NI Water identified a number of upgrade requirements at Warrenpoint WwTW, and planned these over two phases: Phase 1 to be undertaken as part of the EU-funded SWELL Project, and Phase 2 (the focus of this case study) following seamlessly. Phase 1 concentrated efforts on alleviating immediate pollution problems through the installation of a new inlet works, inlet balance tank and screens. This phase also provided three activated sludge lanes for improved biological treatment. The second phase completed the requirements for increased treatment capacity through the provision of new secondary treatment capabilities. In addition, microbial reduction through tertiary level treatment and disinfection, and phosphorus reduction through ferric dosing, ensured compliance with the predicted more stringent discharge consent. Significant improvements were also made to the sludge handling facilities. The end result of the two-phase project is a modern wastewater treatment works that is capable of providing a high-quality effluent for a population of 21,146, providing catchment growth over a 25-year period, improving operational efficiency, and contributing to the quality of the shellfish area in the receiving watercourse.

🍃 Carbon reduction. We're using the PAS 2080 principles in the delivery of a £36m scheme at Newthorpe in Nottinghamshire. We're replacing the existing treatment with a new Enhanced Biological Phosphorus Removal (EBPR) system that will remove phosphorus from the water environment. The scheme includes two new inlet works, an ASP, sludge thickening, final settlement tanks (FST) and tertiary solids removal (TSR). Here's how we're using PAS 2080... ◼ Building less - re-using existing structures where possible ◼ Building smart - including a 20% reduction in ASP volume, use of lower carbon concrete mix, tapered wall designs and fewer internal walls to minimise materials 💻 Read more about the project: https://lnkd.in/gP7B2F_s #engineering #waterindustry #phosphorus #PAS2080 #carbonreduction Severn Trent WaterProjectsOnline

A couple of pilot tests to monitor site decontamination of soil and groundwater from #PFAS; a different start to end up to decontaminate. First phase along this year through a deep dive about investigation and permission request and then turn the page along 2025 through on site implementation of those specific pilot tests. This comprehensive project aims to show up how to apply in concrete pilot tests on site for soil and groundwater decontamination from PFAS. Short summary of 🌍 Soil treatment train will come along through: 🔄 FF ▶ BIO ➡ AOP ➡ GAC The same of 💧 Groundwater treatment train that will come along through: 👉 🚰 Drinking Water AOP ➡ GAC 🔀 👉 🚱 Discharge Water Large scale application?

Earlier this week, our poll asked about the largest amount of liner you've ever seen removed in a day. Well, our team has successfully tackled and removed 1 million square feet of liner in a single day! Managing ponds with liners needing removal? Don't delay—let us handle it for you. Contact us today to streamline your maintenance process and ensure compliance with environmental standards. Call (832) 292-1656 to discuss your liner removal project or visit www.LinerRemoval.com to see our process in action. #OilandGasIndustry #EnvironmentalCompliance #EfficiencyMatters #OilandGas #Energy #CivilEngineering #Infrastructure #Construction #EngineeringProjects #Agriculture #Farming #Agribusiness #SustainableFarming #Geosynthetics #GeotechnicalEngineering

Case Study Spotlight ✨ : Transformative Solutions for Environmental Compliance The Fox River Water Reclamation District (FRWRD) needed to comply with new environmental parameters called for a reduction of phosphorus discharges into the Fox River. FRWRD collaborated with Black and Veatch to conduct a comprehensive feasibility study of their three water reclamation facilities. After considering various nutrient removal processes, they chose Biological Phosphorus Removal (Bio-P) coupled with MagPrex. Since 2021, MagPrex has been a game-changer, consistently removing over 90% of orthophosphate in the digested solids stream. Dive into the details of this success story: https://hubs.ly/Q02j3lZY0 #MagPrex #StruviteRemoval #PhosphorusRecovery

SGMA's goal of sustainable groundwater pumping looks good on paper - if you can wait 30 years - but it does nothing in the near-term to slow down excessive groundwater pumping. A TBI-led collaborative effort with Friant Water Users and the Bureau of Reclamation to evaluate SGMA-mandated groundwater sustainability plans in the San Joaquin River region showed that they all failed to address how pumping depletes flows released to restore the river! So both the environment and water supply infrastructure like the subsiding Friant-Kern canal suffer when the best-laid plans to reduce excessive groundwater pumping, lack proper and timely implementation and enforcement. https://lnkd.in/dG7AtvSP

📣 Today, The Integrity Council for the Voluntary Carbon Market (ICVCM) has announced the first carbon credit categories to be eligible for Core Carbon Principles (CCP) labels. 🌍 This is an important step towards establishing a quality threshold for carbon credits in the voluntary carbon market and beyond. Landfill gases and ozone-depleting substances are the first two activity types announced as CCP-eligible, with specific requirements set on the scale of projects and the methodology version applied. BeZero Carbon has rated eight projects now eligible for the CCP label, ranging from ‘BBB’ to ‘BB’, all in the Landfill gas sub-sectors.

The spread of per- and poly-fluoroalkyl substances has made it harder for organizations to fulfill brownfield regeneration projects. Developers are forced to deal with PFAS’ characteristics as well as the effects of new policies that regulate them. As we celebrate World Environment Day, I would like to put the spotlight on a blog authored by Jake Hurst and Simon Rawlinson that discusses PFAS-related challenges. It provides insights about how PFAS affect the environment and sheds light on different solutions. 📖 Read more here: https://okt.to/zGKE4M #Arcadis #WorldEnvironmentDay2024 #Resilience #Sustainability
