Abstract Three types of odour abatement systems in sewer networks in Australia were studied for 18 months to determine the removals of different compounds. Six volatile sulfurous compounds and seven volatile organic compounds (VOCs) were further investigated. All types of odour abatement systems exhibited good removal of hydrogen sulfide with the biotrickling filters (BTFs) showing the highest consistent removal. Biofilters outperformed BTFs and activated carbon (AC) filters in the removal of dimethyl mono-, di- and tri-sulfide species at the low inlet concentrations typically found. AC filters exhibited little VOC removal with no compound consistently identified as having a removal greater than 0%. Biofilters outperformed BTFs in VOC removal, yet both had high removal variability.

High Concentrations

An air purification system based on the use of specialized catalytic filling, designed to reduce high concentrations of hydrogen sulfide and volatile organic compounds is represented. The system is a 20 or 40 foot heated sea container in which two catalytic charge units are located: one is a working and the other is a reserve. Each block contains one cleaning step with a specialized ferrous charge.

The article describes the air pretreatment system designed to reduce high concentrations of hydrogen sulfide and volatile organic compounds through the use of specialized catalytic backfill. The system is a 20- or 40-foot insulated sea container in which two catalytic backfill units are located. One worker the other reserve. Each unit contains one cleaning step with a specialized ferruginous backfill. The installation does not have its own fan and is connected to the existing ventilation system be installed in front of the installation EVENTLET. The operation of the system is subject to all safety requirements for the operation of electrical equipment, which is powered by a voltage of 380 V and a frequency of 50/60 Hz. The technical characteristics and Assembly of the system are given.
