From gold mining to drinking water, pharmaceutical to food processing — Carbo Fresh activated carbon solutions are trusted across eight industries worldwide.
Activated carbon is the adsorbent of choice in carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold processing circuits — the dominant method for gold extraction from ore slurries globally. In these processes, activated carbon selectively adsorbs gold-cyanide complexes from the ore pulp, concentrating the precious metal for subsequent elution and electrowinning.
Coconut shell activated carbon is strongly preferred for gold recovery due to its exceptional hardness, which withstands the mechanical abrasion of agitated CIP/CIL tanks, and its high iodine value, which delivers superior gold loading capacity.
Activated carbon is a cornerstone of modern drinking water treatment, effectively removing chlorine, chloramines, taste and odour compounds, pesticides, herbicides, disinfection by-products (DBPs), and a wide range of organic contaminants from both municipal and industrial water supplies.
Coconut shell GAC is the preferred choice for drinking water applications — its low ash content minimises leaching of impurities, while its high hardness ensures minimal media loss during backwashing cycles.
Industrial and municipal wastewater treatment relies on activated carbon to remove persistent organic pollutants, COD, heavy metal complexes, dyes, and other difficult-to-treat contaminants before safe discharge or water reuse.
Coal-based GAC is the preferred choice for wastewater applications — its broader pore distribution effectively adsorbs the larger molecular weight compounds commonly found in industrial effluent, while offering a cost-effective solution for high-volume treatment systems.
Activated carbon is widely used in air and gas treatment systems to adsorb volatile organic compounds (VOCs), hydrogen sulphide, mercury vapour, odours, and other airborne contaminants in both industrial and commercial settings.
Both coconut shell pellets and coal-based GAC are commonly used — coconut shell pellets for high-purity or sensitive gas-phase applications, and coal-based pellets or GAC for heavy industrial VOC treatment and solvent recovery.
The chemical industry relies on activated carbon for solvent recovery, catalyst applications, decolourisation, and the purification of chemical streams — ensuring product purity and process efficiency across a wide range of manufacturing processes.
Pharmaceutical manufacturing demands the highest purity standards. Activated carbon is used for decolourisation, purification of active pharmaceutical ingredients (APIs), process water treatment, and wastewater management — meeting stringent GMP and regulatory requirements.
Activated carbon plays a critical role in the food and beverage industry — from decolourisation of sugar and beverages to purification of drinking water, taste improvement, and removal of unwanted compounds from edible products and process water.
Environmental remediation and protection applications leverage activated carbon's broad adsorption capabilities to treat contaminated groundwater, remediate polluted sites, treat landfill leachate, and capture hazardous emissions — supporting cleaner environments for communities and ecosystems.
