Applications
Activated carbon removes dissolved organic compounds by adsorption. We supply grades for drinking water, wastewater, sugar refining and air treatment.
Drinking water
Municipal water plants are our main market. Carbon is used to:
- Remove taste and odour compounds such as geosmin and 2-MIB, mostly during summer and autumn algae events
- Reduce natural organic matter and disinfection by-product precursors
- Act as a barrier against pesticides, algal toxins and selected PFAS compounds (GAC)
Typical products: PAC 325 mesh for seasonal dosing; GAC 8×30 or 12×40 for GAC caps on dual-media filters and post-filter contactors. All certified to NSF/ANSI/CAN 61.
Municipal and industrial wastewater
- Tertiary polishing to lower residual COD and colour before discharge
- Removal of micropollutants such as pharmaceuticals and industrial organics, either by dosing PAC into biological or tertiary treatment or by GAC filtration
- Odour control: impregnated carbon in vessels treating air from headworks, sludge handling and pumping stations (hydrogen sulphide, mercaptans)
Typical products: coal-based PAC and GAC; impregnated pelletized carbon for odour control vessels. We also offer change-outs of the spent carbon in these vessels — see change-out services.
Sugar and food processing
- Decolourization of cane and beet sugar liquors in refining
- Purification of glucose and other food syrups
- Removal of off-flavours and colour in food and beverage process water
Typical products: wood-based, phosphoric-acid-activated PAC for decolourization, available through our supply partners; granular carbon for column systems. Grades are selected by trial on your liquor.
Air and gas treatment
- Odour control at wastewater facilities and industrial sites
- Removal of volatile organic compounds from process vents
- Hydrogen sulphide removal with impregnated carbon
Typical products: 3–4 mm pelletized carbon, plain or impregnated.
