In situ sanering van grondwater verontreinigd met PFAS – Internationale case studies
Oorspronkelijke uitzenddatum: 16 Juni 2020 | Taal: Nederlands | Kosten: Gratis
In deze webinar bespreekt Kris Maerten verscheidene case studies waarbij PlumeStop®, vloeibare (colloïdale) actieve kool, is gebruikt om grondwater verontreinigd met poly- en perfluoralkylstoffen (PFAS) succesvol in situ te saneren.
PFAS-verbindingen, waaronder PFOS en PFOA, zijn wijdverbreid in het milieu. Ze zijn persistent, toxisch, mobiel en bioaccumulerend; zozeer zelfs dat ze in verschillende landen zijn gereguleerd met grenswaarden voor het grondwater van minder dan 50 ng/L.
Momenteel wordt voor dit soort verontreiniging vaak een beheersmaatregel uitgevoerd door middel van Pump & Treat. Deze gebruiken veel energie en moeten doorgaans decennialang actief blijven. Bovendien is de verwerking van de gebruikte actieve kool moeilijk en duur.
De in situ behandeling van het grondwater door middel van injectie met PlumeStop is een bewezen alternatief voor P&T. Deze oplossing beheerst op een passieve en duurzame manier het risico dat gepaard gaat met de PFAS-verbindingen in grondwater. Door de behandeling wordt de bodem als het ware ‘gecoat’ met een dun laagje colloïdale, actieve kool. Hierdoor onstaat een soort ondergrondse actieve koolfilter die snel de PFAS-verbindingen sorbeert. De doeltreffendheid van de behandeling is geïllustreerd door de presentatie van een vijftal pilootproeven en full-scale toepassingen: 2 in de VS, 1 in Canada, 1 in het Midden-Oosten en 1 in Zweden.

Tratamientos in situ de aguas subterráneas afectadas por solventes clorados
Presentado por: Ing. Marcello Carboni (Regional Manager Europe)
Ing. Marcello Carboni presenta varias tecnologías de remediación in situ mediante la aplicación de sustratos inyectables para el tratamiento de acuíferos contaminados por solventes clorados. Durante el seminario web, se describen en detalle 3 opciones de tratamiento diferentes, pasando de sustratos orgánicos ingenierizados para optimizar el perfil de liberación y su distribución en el subsuelo, al uso de productos coloidales de última generación:
- Decloración reductiva mejorada con el uso de sustratos orgánicos electro-donadores con liberación controlada de hidrógeno
- Biodegradación mejorada por adsorción in situ, utilizando carbón activado coloidal
- Reducción química in situ (ISCR) con hierro cero-valente coloidal sulfurado
Al final del seminario web hay una sesión de preguntas y respuestas donde se contesta a varias preguntas.
En este webinar tienes la oportunidad de aprender:
- Los principios técnicos subyacentes a las tres tecnologías in situ
- Los criterios de selección de las tecnologías basados en las características del sitio en términos de contaminación, geología, tiempos de tratamiento y concentraciones objetivo
- Algunos casos de estudio de aplicaciones reales que ilustran los resultados alcanzables con ejemplos prácticos
- La posibilidad de integrar las diversas tecnologías a través de fases siguientes o con aplicación conjunta
La presentación se estructura en torno a los 4 requisitos básicos que hacen exitosa cada tecnología in situ:
- Reactividad: mecanismos de reacción de los productos con los contaminantes de interés.
- Distribución: dispersibilidad, inyectabilidad y rayos de influencia obtenibles
- Persistencia: longevidad extrema de liberación/tratamiento, para poder dimensionar las intervenciones a través de aplicaciones individuales y minimizar los costos de remediación
- Facilidad de uso: uso de equipos de mezcla e inyección fáciles de implementar y seguros para los técnicos de campo

Traitement in-situ d’aquifères impactés par des PFAS – Cas d’études à travers le monde
Première diffusion: 23 Avril 2020
Langue: Français
Dans ce webinaire, Aurélien Triger, Représentant Technique France, a discuté de plusieurs études de cas de traitement in situ de PFAS durant lesquels PlumeStop® Charbon Actif Liquide TM a été utilisé pour traiter avec succès des contaminants poly et perfluoroalkyles (PFAS) dans les eaux souterraines.
Les composés PFAS, y compris le PFOS et le PFOA, sont répandus dans l’environnement, récalcitrants et bio-accumulatifs, à tel point que dans plusieurs pays ils ont été réglementés avec des valeurs limites pour les eaux souterraines inférieures à 50 ng / L. Traditionnellement, les aquifères impactés sont gérés avec des systèmes Pump & Treat (P&T) à haute intensité énergétique, qui nécessitent un fonctionnement actif pendant des décennies et avec des problèmes importants pour l’élimination des résidus de traitement.
L’injection in situ de charbon actif colloïdal PlumeStop est une alternative éprouvée au P&T. Cette solution gère de manière passive et durable le risque associé aux composés PFAS dans les eaux souterraines. Lors de l’injection, PlumeStop recouvre la matrice solide de l’aquifère de charbon actif colloïdal. De cette façon, une zone d’adsorption in situ perméable est créée dans le sous-sol. Elle élimine rapidement les contaminants PFAS présents dans la phase mobile dissoute.
L’efficacité du traitement sera illustrée au cours du webinaire à travers la présentation de tests pilotes et de projets à grande échelle à travers le monde entier, dans lesquels des applications individuelles de PlumeStop ont conduit à une diminution des concentrations dans les eaux souterraines en dessous des limites de détection.
La présentation comprend des données de:
- Données d’un projet de réhabilitation sur un grand site Superfund (US)
- Test pilote sur un site militaire (États-Unis)
- Réhabilitation à grande échelle dans un ancien site industriel (Canada)
- Traitement à grande échelle dans une installation de stockage en vrac (Moyen-Orient)
- Projets récents et en cours (Europe)

L’AFITE a récemment publié un article dans son magazine sur le développement de PlumeStop comme solution de remédiation in situ pour traiter les PFAS, basé sur la présentation donnée par Aurélien Triger et Kris Maerten à la Réunion de sa Commission «Site et Sols Pollués ”à Paris le 11 octobre 2019.

Trattamento di elevate concentrazioni di idrocarburi: casi di studio di adsorbimento in situ
Presentato da: Ing. Marcello Carboni (Regional Manager Europe), Ing. Mariangela Donati (Mediterranean District Manager)
In questo webinar in diretta l’ing. Mariangela Donati e l’ing. Marcello Carboni illustrano i fondamenti teorici e gli aspetti operativi dell’utilizzo di carbone attivo liquido alla micro-scala per trattare contaminazioni derivanti da perdite di idrocarburi, spill di oli e plume storici.
PetroFix® è una sospensione acquosa di carbone attivo colloidale di dimensioni 1-2 µm e accettori di elettroni biostimolanti. Il trattamento consente di combinare l’adsorbimento in situ con la biodegradazione sintrofica di tipo anaerobico. Ciò consente di gestire efficacemente concentrazioni elevate di idrocarburi, fornendo un trattamento immediato e risultati di bonifica duraturi.
Questo webinar affronta i seguenti argomenti:
- Descrizione dettagliata del processo di bonifica
- Rapido adsorbimento degli idrocarburi petroliferi
- Biodegradazione anaerobica potenziata
- Scenari di applicazione utilizzabili
- Iniezione direct push
- Iniezione attraverso pozzi
- Applicazione in scavo
- Approcci preventivi
- Discussione di diversi casi di studio
- Informazioni acquisite dall’esperienza sul campo
Si ritiene che questo webinar sia di estremo interesse per chi opera professionalmente nella progettazione e nell’esecuzione di interventi di bonifica di siti contaminati da idrocarburi, per le società che intervengono in emergenza a seguito di eventi accidentali, per gli Enti di controllo e per chi possiede o detiene siti oggetto di bonifica.

Pathway to Remediation Success: A Next-Generation Approach to Complex Contaminated Sites
In this webinar we are pleased to have as special guest speakers John Hesemann, Remediation Technical Practice Leader, and Rick Cramer, Environmental Sequence Stratigraphy Practice Leader of Burns & McDonnell. Their presentation discusses the next generation approach to tackling remediation of complex contaminated sites. They are joined by Craig Sandefur, Vice President of Technical Services at REGENESIS, who discusses Design Verification Testing (DVT) activities to improve performance results and reduce project costs at contaminated sites.
Highlights of this free webinar:
- Learn how a focus on Remediation Geology defines the “static” subsurface framework that is the primary control on subsurface fluid dynamics.
- And how this, combined with improved understanding of subsurface processes, results in a Process-Based CSM that informs all stages of the remediation life cycle.
- Case studies presented will show how this approach applies to all complex sites, regardless of location, contaminant, and subsurface conditions.
