Waste Handling Odour Control in Transportable Containers

When dealing with high flow odour control systems ( e.g. waste Transfer Stations or Waste reception facilities) then we can design a variety of different orientated systems within transportable freight containers to save cost and minimise footprint.

Our designs can handle up to 67,000 m3/hr per system and typically include for the dust filtration, extraction duct as well as the extraction fan and industrial carbon adsorber itself.

In this example the System air flow requirement is 66,000 m3/hr nominal and the project included the entire system with exhaust stack. The abatement itself included 2 stage filtration  prior to the adsorber to prevent the carbon from being blinded by dust. In this case the adsorber has 2 internal beds with access for extraction and replenishment from the top. An internal baffle arrangement ensure full carbon utility and even flow through the beds.  01534644cfc1d8cc6acce003aeabcc1f7bfa83d404

The above project was undertaken through Filtrex Limited and with manufacture and installation contributions from Metalcraft Ltd.

What other Technologies are viable for the Waste Industry?

 

There are a range of different waste handling processes and waste types. They range from Food waste handling ( often with Anaerobic Digestion plants) to municipal and green waste handling. Within the waste types there are transfer stations, autoclaves, Dirty and clean side MRFs, Hammer mills, incineration and numerous other combinations of processes. Each of the different types of process require different approaches.

We can design systems based around adsorbers, biofilters, Regenerative or recuperative oxidisers and various types of chemical scrubbers. Sometimes a process may require more than one technology depending on the stack emission consent.

The extraction system is vital in terms of ensuring capture and containment of odours with the minimum amount of required air. The optimisation of extract air is a broad and often political aspect of the design basis. We tend to use CIBSE guides and then Chemical Engineering calculations to interrogate the process and determine the best extract philosophy. Only then can you hope to determine the optimum abatement technology.
