Carbon Engineering
Puragen has developed a comprehensive range of activated carbons, engineered for specific applications and upgraded as needed through resizing and impregnation to meet any filtration requirement.
Carbon Engineering for performance
We optimise activated carbon for each filtration challenge — whether that’s for specific contaminant profiles, to manage performance and efficiency or to meet new regulations.
We develop and source products with specific characteristics, including pore size distribution, surface chemistry, and particle sizing.
We also offer custom impregnation to enhance performance against targeted contaminants, such as hydrogen sulfide, mercury, or ammonia.
From emerging contaminants in groundwater to optimising taste in bottled beverages, we can supply a carbon product that meets requirements consistently and with full technical support.
Carbon Engineering for flexibility
Alongside adsorption efficiency, we can also optimise carbons for system compatibility, flow dynamics, and longevity.
We adapt carbon form factors to match system design — from granular carbons engineered to minimise pressure drop in high-flow mobile units, to tighter particle distributions for fixed beds that require consistent contact times.
Where our customers face operational constraints, we engineer filtration media to perform reliably, efficiently and cost-effectively.

Sand
For some remediation projects it is necessary to pre-treat the groundwater through a sand filter, to remove particulates and prevent ‘blinding’ of the GAC filters. Puragen can offer this service alongside our activated carbon filtration systems.
