Activated Carbon Media

Activated carbon is one of the most effective media for removing a wide range of contaminants from industrial and municipal waste waters, landfill leachate and contaminated groundwater. As the world�s most powerful adsorbent, it can cope with a wide range of contaminants. Different contaminants may be present in the same discharge and carbon may be used to treat the total flow, or it may be better utilized to remove specific contaminants as part of a multistage approach.
Advantages
the typical range of environmental water contaminants that activated carbon is used to treat includes:
� non-biodegradable organic compounds (cod)
� adsorbable organic halogens (aox)
� toxicity
� colour compounds and dyestuffs
� inhibitory compounds for biological treatment systems
� aromatic compound including phenol and bis-phenol a (bpa)
� chlorinatedhalogenated organic compounds
� pesticides
benefits
the benefits of this process include:
� improved removal of biochemical oxygen demand (bod), chemical oxygen demand (cod), non-biodegradable organic compounds and toxicity
� increased stability to shock loads
� removal of inhibitory compounds including for nitrifying bacteria
� improved sludge dewatering
� reduced aerator foaming
