Carbón activo para PFAS

Active Carbon is one of the best available techniques to remove PFAS from potable water, ground water and industry waste. It has a unique ability to adsorb PFOS and PFOA at trace levels, providing a reliable, regulated treatment in areas where PFAS is most hazardous for public and environmental protection.

What is PFAS Activated Carbon?

The impact of PFAS pollution on public health is serious and well documented. Exposure to some PFAS compounds — especially PFOA and PFOS — has been associated with the destruction of the thyroid gland, the inhibition of the immune system, the increased risk of cancer and the development of infants. The response from regulators such as the U.S. EPA, European Chemicals Agency and national environment authorities in Asia and Pacific has been to enforce MCLs (MCLs) and mandatory drinking water standards, prompting an immediate need for efficient, scalable disposal techniques. Active Carbon — either in granular (GAC) or in powder form (PAC) — has become a proven, cost effective and widespread deployment of PFAS disposal in urban, industry and remediation applications.

Key Advantages of PFAS

Proven Adsorption Affinity for PFAS Compounds: Due to the PFAS and the active carbon surface, the hydrophobicity and static interaction of the PFAS and the active carbon surface enables a robust, selective absorption – especially for long chain PFAS like PFOA and PFOS – to reach a safe elimination level lower than the regulation level.
Scalable for Municipal and Industrial Flow Volumes: Particulate active carbon fixed bed systems can be designed for continuous treatment at a high flux, which is a first choice for urban potable water facilities, military installations, and large scale industrial waste disposal projects.
Flexible On-Demand Deployment with PAC: PAC makes it possible for PFAS to be treated quickly, with no special infrastructure investment, so that the utility can react promptly to a pollution incident or a seasonal peak in the absence of capital changes.
Regulatory Compliance Across Multiple Frameworks: The U.S. EPA's Drinking Water Guidelines, the European Water Framework Directive's Water Framework Directive, and comparable national norms -- provide a compliant solution that is compatible with existing and expected PFAS rules worldwide.
Cost-Effective Versus Alternative Technologies: Compared with ion-exchange resins, membrane filters and advanced oxidation techniques, the active carbon provides a competitive PFAS removal capability with considerably reduced capital and operating costs -- especially beneficial in the case of high volume, low density handling.

Vast Number of PFAS Compounds

Since more than 12 000 different PFAS agents have been identified, there is no one treatment method that will ensure consistent elimination effectiveness for all mixtures, which will need to be carefully selected and systematic in order to efficiently deal with the site specific PFAS profiles.

Short-Chain PFAS Are Harder to Remove

Newly developed short chain PFAS substitutes like PFBS and PFBA show lower absorption of active carbon on the active carbon surface compared with their long chain ancestors.

Spent Carbon Disposal and Regeneration Complexity

The problem of PFAS-laden PAC is a concentration of hazardous waste treatment since heat activation has to be achieved at a temperature sufficient for PFAS to be destroyed and no deleterious by-products are emitted to the air.

Specific Use Scenarios — Activated Carbon For PFAS

Municipal Drinking Water Treatment

Particle Active Carbon (GAC) is one of the largest installations in PFAS disposal in urban wastewater treatment plants. The GAC contactor is located following the usual filtering steps in which the source water is transferred to a solid carbon bed which absorbs the PFAS compounds prior to its distribution. GAC systems have been designed to deal with a large number of days of continuous operation, with the removal of spent carbon for off-site heat activation and recommissioning, offering cost management, long term compliance solutions for utilities that are confronted with enforceable PFAS MCLs.

Point-of-Entry and Point-of-Use Filtration

Active Carbon Point Entry (POE) and Point of Use (POU) are available for the smaller communities, the privately owned, and the residents affected by the PFAS-contaminated source water. Block Carbon Filters and Particulate Carbon Assemblies located at the Entrance of a Building or Individual Tap Level provide an efficient PFAS Reduction for Domestic Potable Water and Potable Water Supply and Provide Immediate Deployment Solutions with Large Scale Centralised Infrastructure Design or Modernisation.

Groundwater Remediation

PFAS pollution in ground water aquifers — often caused by AFFF applications in military facilities, airports and industry — is among the world’s most complicated and extensive environmental remediation problems. Active carbon is used in the treatment of wastewater treatment systems, which are pumped out of polluted ground water, transferred to a GAC interface for PFAS absorption, and then re-injected or released into the surface water. GAC’s ability, durability, and operating flexibility have enabled it to become a leading technique for PFAS remediation projects around the world.

Industrial Wastewater Treatment

The industrial sectors, which comprise the manufacture of semiconductor, metal-plating, textile, and paper-making, produce a process waste stream comprising PFAS compounds at a concentration which has to comply with the discharge authorisation threshold prior to being discharged into the urban sewage system or the surface. Active Carbon – in GAC fixed and PAC dosage configurations – is incorporated into an industrial waste disposal system to absorb PFAS from a complicated waste water matrix, allowing the installation to meet ever stricter industry emission standards.

Landfill Leachate Treatment

Landfills where PFAS-containing products, packing materials and fire-fighting foam have been used in the past produce a flow of leachate with increased levels of PFAS which, if left untreated, present a serious risk of groundwater pollution. Active carbon treatment — usually PAC injected into a leachate collecting system or a GAC interface at a specialized leachate treatment facility — provides efficient PFAS capture from such high strength and chemical complexity flows, thereby avoiding the subsequent transfer of the environment from the legacy facility.

Emergency Response to PFAS Contamination Events

When PFAS pollution is found in the potable water supply at a level above the regulatory action threshold – caused by an industrial spill, a fire extinguisher, or a recent discovery of a legacy pollution – the need for rapid response management solutions that can be deployed without the need for a long period of infrastructure purchase. The addition of PAC (PAC) to the existing processing tanks provides an instant PFAS reduction capacity that enables the operator to keep a secure flow of water during the design, procurement and commissioning of a permanent GAC contactors.

PFAS Removal in Food and Beverage Processing

If PFAS compounds are found in the final products, food and drink producers who purchase process water from PFAS-impacted suppliers will have to comply with the regulation as well as the risk of brand integrity. Active Carbon Polishing Filter – which is installed at the end of the processing phase prior to the start of the process – effectively prevents the transfer of PFAS into the FCM application, and promotes the observance of the FSS rules and the protection of the quality of the product in the vulnerable manufacturing environment.

High-Affinity PFAS Adsorption Performance

The hydrophobic chemical properties of the active carbon and its well-developed pore architecture provide a robust, selective absorption of PFAS compounds -- PFOA, PFOS and its derivatives -- to reach the U.S. EPA and the International Monitoring Limits for Various Sources of Water.

Flexible Deployment for Any Scale or Scenario

Active carbon, which is available in both granular (GAC) and powdery (PAC) forms, is suitable for a wide range of PFAS disposal requirements -- from large-scale GAC contactors that process millions of gallons per day to fast PAC dosage for emergency pollution management -- with no specific new infrastructure being necessary.
