NORIT activated carbon is widely used for micropollutant and PFAS adsorption, and now, PFAS destruction in reactivation is demonstrated.
NORIT is one of the world’s largest and most experienced producers of activated carbon and offers you a full range of products, services and technical support.
NORIT’s history of innovation, product performance, technical expertise and our customer focus ensure that you receive the right products and solutions for your specific purification needs.
NORIT’s activated carbon products are used to remove pollutants, contaminants and other impurities from water, gas and air, food and beverages, pharmaceutical products and other liquids in an efficient and cost-effective manner. Our activated carbon solutions are also used as colourants, carriers or catalysts in industrial processes.
Building on a 100+ year history of innovation in manufacturing and product development, we produce a diverse array of products from a wide range of raw materials, including lignite, peat, bituminous coal, coconut and wood. We have created more than 200 different grades of activated carbon, ensuring you never need to force-fit a NORIT carbon and always achieve the best possible performance.
Global presence and full service
NORIT operates a global network of plants for the production and reactivation of activated carbons. We offer a comprehensive logistics service to our customers, organising transport in dedicated tank cars that are exclusively used for NORIT carbons. Our sales are organised locally, so there is always a NORIT contact near you.
We have global teams of application specialists to help our customers achieve the best performance and select the most appropriate carbon type. Might further carbon development be required? We have two R&D centres, one in the USA and one in the Netherlands, focusing on carbon development, technology improvement and customer support.
NORIT activated carbon for PFAS removal
Activated carbon treatment is generally recognised as the most mature and most widely adopted treatment technology for PFAS removal. Just as activated carbon has been used for decades to remove various organic pollutants from water streams, such as pesticides and taste and odour-causing compounds, keeping drinking water safe, it is also effective in removing PFAS from water streams. In fact, activated carbon has been removing PFAS from water streams for decades.
NORIT carbons have consistently demonstrated high removal efficiencies for PFAS, both with powdered activated carbon (PAC) and with granular activated carbon (GAC). Several third-party studies confirmed the superior PFAS adsorption properties of our carbons.
Water matrices vary from waterwork to waterwork, from groundwater to surface water and from wastewater to drinking water. With the changing water matrix, the choice of carbon will also change, to achieve the best possible performance depending on the conditions at hand. NORIT has a team of application specialists ready to help our customers select the optimal carbon types for their purification challenge.
NORIT reactivation of spent GAC leads to PFAS destruction
Offering a full portfolio of products and services to the water industries, NORIT operates a network of reactivation plants where spent GAC can be reactivated and subsequently reused. In a recent study, NORIT demonstrated the destruction of PFAS during the reactivation process, freeing the carbon completely of adsorbed PFAS, restoring the PFAS adsorption capacity and subsequently destroying the PFAS for 99.98% in the reactivation kiln and afterburner. This means that GAC treatment is not only a means to remove PFAS from water streams but also leads to the near full destruction of PFAS, highlighting the suitability of the technology to deal with the PFAS challenge, and making an end to ‘forever chemicals’.
Current R&D efforts are aimed at further improving our grades for PFAS adsorption, including better removal of the shorter chain PFAS types, and demonstrating performance at various water matrices.
