Activated carbon.
Exceptional adsorption performance for a wide range of purification needs, from water treatment and air filtration to gold recovery, in custom grades matched to your requirements.
High-grade carbon, matched to the job.
AirAqua distributes premium activated carbon from our exclusive partner Gaia Carbon across Australia and New Zealand. Every grade is steam activated for a deep, consistent pore structure, so the right carbon removes contaminants faster and lasts longer in service.
Multi-point steam activation
A controlled process that builds a balanced network of micro, meso and macropores.
Coconut shell, coal and wood-based
Choose the base material for your application, from drinking water to heavy industry.
Custom grades and sizes
Granular through to powdered mesh, supplied in 25 kg bags or bulk bags.
One material, three ways to clean up.
Liquid phaseWater treatment
Granular carbon removes chlorine, organic contaminants and odours, improving taste and keeping water safe.
- Drinking and process water
- Wastewater and effluent polishing
- Heavy metals, mercury and trace organics
Gas phaseAir purification
Captures VOCs, sulphur compounds and industrial emissions to deliver cleaner air and support compliance.
- Indoor air filters and deodorisation
- Industrial process gas and flue gas
- Odour control at sewage plants
Gold recoveryPrecious metals
Essential in gold mining, where it extracts and separates metal in carbon-in-pulp and carbon-in-leach circuits.
- CIL, CIP and CIC circuits
- High loading and elution rates
- Hard, attrition-resistant granules

Built to hold on to every gram.
GaiaGold is a coconut-shell carbon with a large pore volume and exceptional hardness, so it loads gold quickly and resists breakdown in the circuit, limiting fines, losses and downtime.
| Specification | A280 | A320 |
|---|---|---|
| CTC activity | 55% min | 60% min |
| Ball pan hardness | 99% min | 99% min |
| Attrition | 2% max | 2% max |
| Platelet | 4% max | 4% max |
| Mesh | 6×12 / 6×16 | 6×12 / 6×16 |
Cleaner air, captured at the source.
Gas-phase carbon adsorbs volatile organic compounds, hydrogen sulphide, ammonia, formaldehyde and mercury from industrial emissions and indoor air, helping sites stay compliant and neighbours comfortable.
PFAS reduction.
Perfluorinated compounds are persistent and a growing concern for water quality. The PF grade carbon is engineered for PFAS removal, with a pore structure that combines micro, meso and macropores to capture these contaminants from ground and surface water.
| PF grade | Limit | Value |
|---|---|---|
| Iodine adsorption | minimum | 1000 mg/g |
| Apparent density | maximum | 440 kg/m³ |
| Moisture, as packed | minimum | 5% |
| Total ash content | maximum | 10% |
| Ball pan hardness | minimum | 93% |
- Superior hardness, clean with low ash
- Drinking water grade
- Approvals: NSF, Kosher and Halal
