Dry Media Filters

In partnership with our carbon and dry media framework suppliers, ERG offers 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 stand-alone 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.

ERG has treated air flowrates of less than 50m3/hr up to more than 80,000 m3/hr with a single vessel, and has a variety of configurations to offer, including deep bed, dual deep bed, annular and modular section vessels.  

Working to suit our client's requirements, ERG optimises each dry media filter design based on the required outlet emission, the specified bed life between media changes, the space available, the air flowrate, and the capital cost. And with more than 100 dry media filters installed and performing successfully since 1998, each filter system is backed by the confidence of ERG's extensive experience.

Each filter is tailored to treat the contaminant odours. We can offer systems to treat H2S, mercaptans, organic sulphides, ammonia, amines, and VOCs in any combination, and can also provide a guarantee of outlet odour concentration in ouE/m3.

Designed and built to BS4994 and fully compliant with WIMES 8.05, ERG's dry media filters offer assured performance at a competitive price.
