ERG - Carbon Filters for Odour Control in the Water Industry
We offer a comprehensive range of activated carbon, impregnated carbon, oxidising alumina media, and hybrid, multi-media filters. For the Middle East market we also offer in situ water and chemically regenerable carbon. An ERG dry media filter may be used as a standalone filter for polishing a chemical scrubber discharge or as part of a DryCat system. All our dry media filters require no operator intervention and provide guaranteed odour control performance.

Alkali impregnated carbon
Pelletised for low pressure drop, up to 25%w/w take-up of H2S, good mercaptans removal
Acid impregnated carbon
Pelletised or granular, up to 8%w/w take-up of ammonia
Activated carbon
Pelletised or granular, for VOC removal
Water regenerable carbon
Pelletised, up to 20% w/w take-up of H2S, regenerable using water for up to 8 cycles. Operational cost savings
