ACTIVATED CARBON THAT ALWAYS FITS!
As the official Swiss agent for NORIT ACTIVATED CARBON, Dolder offers more than 150 types of activated carbon made from different raw materials. In addition, we offer solutions in the exchange, reactivation, analysis, and disposal of activated carbons, as well as the rental of mobile filters.
This product is available in following country: Switzerland
WHAT IS ACTIVATED CARBON?
Activated carbons are carbonized absorption substances with high inner porosity and as a consequence, a large interior surface. Absorption is the process for removing liquid substances. Impurities are held inside the carbon material by electrostatic attraction (Van-Der-Waals forces) or chemisorption.
PROPERTIES
Depending on the area of application, activated carbons offer the following properties:
- Absorption of all organic substance
- Reduction: for example, the chemical removal of chlorine from water
- Activated carbon can catalyze a series of chemical transformations or it can be the carrier of the catalytic agent (e.g. a precious metal)
ACTIVATED CARBON IS A PERFECT CATALYST
- As a biomass carrier: carrier material in biological filters
- As a carrier of chemicals, e.g. for the delayed release of color: In liquorice, activated carbon supplies the typical black color
IN WHICH FORM IS ACTIVATED CARBON AVAILABLE?
The selection of the optimal activated carbon depends on various factors. In addition to the material data, other process-specific factors play a big role. Typically, powder activated carbons are added during the process (gas or liquid) and separated from the carrier by filtration or passage after a certain contact time. Important parameters are the required contact time, the dosing, the system used, the single- or multi-stage dosing, the activated carbon separation, as well as the existing safety measures.
Activated carbon granulate (ACG) is used primarily in fixed filter beds. The most important parameters include the required contact time, the use of a permanent or mobile absorber, the existing facilities for filling and draining, and the specified safety measures. Activated carbon granulate can be regenerated off or on-site.

NORIT® SAE SUPER
FOR MUNICIPAL WASTEWATER TREATMENT
Activated carbon is increasingly used to adsorb contaminants of emerging concern from wastewater effluent to prevent their release to surface waters. These contaminants can include endocrine disruptors, hormones and pharmaceutical residuals.
HOW TO TACKLE CONCENTRATED ORGANIC WASTES
Residential and commercial wastewaters tend to contain concentrated organic wastes that are readily biodegradable in a traditional municipal wastewater treatment plant. We provide activated carbon to help municipal wastewater treatment plants meet stringent, regulatory-driven effluent water quality criteria by removing pathogens, oxygen demanding compounds, and inorganic and synthetic organic chemicals.
GRANULAR ACTIVATED CARBON (GAC)
Granular activated carbon (GAC) is used in fixed filter beds, standalone adsorbers, or in a moving bed configuration, while powdered activated carbon (PAC) is typically dosed into a coagulation/flocculation tank or applied in combination with an active sludge process. We are proud to introduce you to our best grade of powdered activated carbon:
NORIT® SAE SUPER (PAC)
ELIMINATES 80% OF MANY MICROPOLLUTANTS (MP)
NORIT® SAE SUPER (PAC) eliminates 80% of many micropollutants (mp) with a pac dose of 10-20 mg/l! It is the industry benchmark in terms of performance, delivering extremely high MP elimination at low PAC dose rates). The carbon is highly mesoporous, which reduces the effect of pore blocking from adsorption of the dissolved organic carbon (DOC) fraction, and highly microporous, which enables the adsorption of MPs.
