The main issue with this kind of atmospherical pollutions is to minimise the exposure of factory operatives to the dust emission.

It can be achieved by the correct sizing of capture systems (hood and push pull systems) which are able to catch dust local to where they are produced, limiting their dispersion into the working environment.

When dust is transferred in ventilation system’s it has to be removed from extracted air by an appropriate air treatment systems i.e. (bag filters, drawer’s filters, wet filters, etc.).

Abatement of odour and VOC emissions generated by the asphalt production and processing industry using chemical scrubbers and biofilters

The production of bitumen involves the release of fumes containing mainly hydrocarbons and hot gases.

Air Clean has extensive experience in building plants for the treatment of fumes from industrial bitumen, primarily through the use of scrubbers and biofilters.

In particular, the biological filters have proven to be particularly effective for the removal of aromatic hydrocarbons (benzene, styrene, toluene).

Dust removal in the bricks and concrete production factories using dry filters

One of the problems associated with the production of bricks and cement is the production of dust.

The powders are mainly generated in the grinding stages of the raw materials. The production of cement dust is another source constituted by production furnaces whose emissions must be extracted and properly treated.

The technologies used in these cases are made up of dry filters, typically bag filters and electrostatic.

Removal of odour and VOC produced by drying furnace installed in the bricks factories using scrubber and biofilter

In the brick and cement production factories the air expelled from the production ovens can hold a plurality of volatile compounds which often cause bad odours.

Air Clean has produced many successful applications by the use of chemical pre-felling, typically soda scrubber for the removal of acids and subsequent gas VOC removal by biological oxidation.

Removal of dust generated during the refractory bricks production

The production of tiles in refractory material for lining of furnaces and of thermal reactors is often as source of dust production.

Air Clean has considerable experience in this area having made several plants for the abatement through the use of dry filters.
