Odour reduction for Anaerobic Digestion (AD) plant
The facility processes food waste to create renewable biogas and electricity. The Depack facility has a high odour level from the processing of this waste and was causing local complaints, as well as odours spreading within the offices. An existing ionisation system was not providing any benefit.
Following detailed analysis of the existing plant and operations, odour modelling and surveying, a twin dual – bed activated carbon unit was designed and installed complete with 90KW fan and 18M stack and access gantry. A high-efficiency particulate prefilter section ensured protection and maximum life of the 2-stage carbon bed.
The resulting odour tests were very successful, having reduced odours from around 6000 ouE/m3 at inlet to around 200 ouE/m3 at the outlet. Tests taken again after 6 months showed this being maintained.
