Environmental problems, due to municipal solid waste treatment, are dust and odour emissions.

Dust removal is usually done by bag filters.

Odour removal is achieved by a chemical acid wash which remove’s ammonia, followed by a biological filtration stage for oxidation of organic and inorganic compounds.

Biolflters are available utilising traditional organic media biofilters (ex. woods chips, heather, mixed fibrous peat) as required for air bio- filtration.

Air Clean are the distributors of patented MónaFil® material, made from high quality peat (high density and Lignin content) with a controlled particle size. With this high quality engineered media it is possible to install deep bed biofilters up to 3 meters high (reduced footprint). These systems are characterized by a long media life and low pressure loss’s (low operating costs),and with high removal efficiency (plants are being installed to achieve 300 ou/m3 emissions starting from concentration input higher than 50.000 ou/m3 ).

The solid waste treatment plants are often a source of air pollution in the form of mal odour’s. The main pollutants responsible for bad smells are constituted by terpenes developed during the processing of the waste. Very often there is also ammonia derived from the breakdown of proteins under anaerobic conditions.

Air Clean has over twenty years in the application of these systems for the control of the odors from these plants. The systems normally consist of a chemical scrubber for the removal of ammonia and dust followed by an organic media biofilter for removal of odors. As regards the filtering materials, different types of filter materials are available: from simple soil improver compost’s to highly engineered materials characterized by high durability, low pressure losses and extremely high removal efficiencies.

In waste sorting plants, the main problem is very often dust emissions.

Air Clean manufactures particulate removal systems using either wet methods (floating scrubber) or using dry systems (cyclones and bag filters).

Very often these emissions also contain odourous chemical compounds and therefore additional treatment is required for their reduction using various technologies (chemical scrubbers or biofilters).

The waste incineration plants develop high temperature gaseous emissions containing dust, acid gases, VOC.

Air Clean is able to design, build and install complete abatement plants. These normally provide for the injections of calcium carbonate for the neutralization of acid gases, a bag filter for recovery of the carbonate powder and the gas dust collection, and treatment systems finishers for the removal of VOC.

In waste incineration plants was the load of waste are normally kept in depression and the air used as co-cleaner air for the incineration process. At a time when the incinerator is off (maintenance) must be maintained in the depression was and deodorization. Since the intermittent emission the most appropriate technology is very often constituted by a system of absorption to activated carbon.

When a landfill is running low the gases may have a low methane content not enough to support self-combustion.

However, these gases are gases that have a content of malodorous substances. The solution that is normally practiced is to convey these gases to a biofilter and to biologically treat malodorous pollutants and residual methane.
